Portable Braking System

Helpful Hint! Before you begin the initial installation, verify that you have
power in the towed vehicle's 12 volt outlet (with the key in the "tow" position).
Some new vehicles only have power at the outlet when the vehicle is running.
If you do not have power, you can install Roadmaster’s optional 12 volt outlet
kit number 9332. When installed, this outlet will provide power even when the
engine is off.
Important! Some vehicles do not have 15 amps of power going to the
cigarette outlet. This system requires 15 amps of power. It will not function
properly with less than 15 amps. To remedy this situation, refer to the “install
optional 12 volt 20 amp power” section in this manual.
1. Remove the braking system components from box and attach adjustable
seat pad to the unit using the adjustment knob. The adjustable seat
pad also functions as a carrying handle.
2. Adjust driver’s seat to rearmost position.
3. Place the unit between driver’s seat & brake pedal in the
approximate position it will sit in when connected to the brake pedal.
Helpful Hint! The braking system may be placed in the vehicle without the
handle attached if that provides the best fit.
4. Make sure that all of the air in the system has been released by
depressing the air relief button. Any remaining air in the system will
prevent the cylinder from extending when trying to connect to the car’s
brake pedal.
5. Disengage catch on pedal clamp as shown in Figure 1 and fully open pedal clamp.
DO NOT PLUG INTO CIGARETTE
LIGHTER AT THIS TIME.
Doing so may cause unexpected operation the braking
system resulting in personal injury or property damage.
CAUTION
!

Installation READ ALL INSTRUCTIONS FIRST BEFORE
INSTALLATION OR OPERATING.
Never plug this unit into 12 volt outlet until braking system is
completely connected to brake pedal and installed according to
installation instructions. Once it receives power, any movement of the box could cause the unit to
activate unexpectedly. Similarly, never try to un-install the unit without first unplugging the 12 volt
cord. Failure to install and operate the braking system as instructed may result in property damage,
personal injury or death.
WARNING:
!
Not for use on older vehicles without power brakes. This system is
designed to work with vehicles that have a power brake system (even
though the power brakes are not activated while towing). Using this unit on vehicles that do not have
power brakes will result in over-braking and severe non-warranty brake damage.
WARNING:
!
Important! Although this system fits most vehicles as is, with no modifications needed, it may be necessary in some
cases to gain additional clearance over obstructions on the floor. In other cases, it may be necessary to extend the reach
of the unit to ensure a secure and stable fit. To accommodate every possible floor configuration and contour, Roadmaster
has developed cylinder arm extensions in two sizes (#9336 and #9336-3), as well as feet extensions (#9337 and #9337-
4). These extensions allow you to install in virtually any vehicle. The cylinder arm extensions increase the reach of the
the unit. Use a cylinder arm extension if the distance between the driver's seat and the brake pedal is too far to maintain
a secure anchor point between the driver's seat and the braking system’s seat pad - If the unit is properly installed to the
brake pedal and there is a gap between the seat and the seat adjustment pad, use a cylinder extension of the appropri-
ate length. Use one or more foot extensions to elevate over obstructions such as duct work, a door jam or a center
console that juts into the available space, or if the floor is significantly out of level.
For further information, refer to "Optional Equipment" on page 15.

11. Plug the 12 volt cord into the power outlet. Secure cord using the cord lock as shown in figure 2a through
2c. IMPORTANT! You must push the cord lock forward into the cigarette lighter to properly secure the
plug. Failure to use the cord lock may allow the plug to vibrate loose, causing intermittent power supply
and the Receiver lights to flash. If your Receiver lights flash for no apparent reason, verify that the 12 volt
plug is properly secured with the cord lock.
12. At this time, the red light on the 12 volt plug should illuminate. If not, you have no power. Some cars have
no power to the cigarette lighter connection unless the ignition is on. In that case, use part number 9332
(not included) to add a 12 volt outlet.
13. Once you have power, the compressor should run briefly.
Make sure the brake pedal is not being depressed as this will apply the brakes
causing severe brake damage or even a brake fire.
THIS WILL NOT BE COVERED UNDER WARRANTY
CAUTION:
!
CHECK 12 VOLT OUTLET BEFORE PLUGGING IN THE UNIT. If you use any
12 volt socket other than your car’s factory wired outlet, make certain that the
socket has been wired correctly. The bottom center of the 12 volt outlet is
always positive while the round outer shell is always negative. If the positive and negative wires are
reversed, you will blow the 20 amp fuse in the end of the 12 volt power cord.
CAUTION:
!
Installation continued
6. Place pedal clamp so that the bottom tabs are hooked on brake pedal as
shown in Figure 1a. Now compress pedal clamp at top and bottom and
ratchet it down until fully secure on brake pedal as shown in Figure 1b.
Use pliers to bend the five tabs in Figure 2, to properly fit your car’s brake
pedal.
IMPORTANT! Verify that the clamp is right side up as shown in
figure 1a. The sticker will point up when properly positioned.
7. Now move the braking system forward until cylinder is fully collapsed.
8. Make sure the unit is approximately level. Adjust the feet on the bottom of the braking system making sure
that all four feet are making contact with the floor of your vehicle.
IMPORTANT! Once level, make sure lock nuts are tightened to secure feet. Feet may be
removed if necessary or for fit options use feet extender parts #9337 & 9337-4 found in the optional
equipment section featured later in this manual.
IMPORTANT! The braking system must be close to level to operate properly.
9. Loosen knob on back of the unit to adjust seat pad up or down as necessary to match seat height.
Note: Adjustable seat pad may be rotated 180 degrees or removed for better fit. There are also two anchor
holes that the adjustment knob may be threaded into for additional fit adjustment
10. Now slide seat forward against the braking system adjustable seat pad. Once again, be certain the unit is
not depressing brake pedal.

Make sure you bend the five tabs on the pedal clamp to
tighten around your brake pedal securely. If loose the pedal
clamp can get out of position and hold the brakes in the on position even when not
braking. This would result in non-warranty brake damage.

15. Set “Brake Sensitivity” to number 2.
16. Set “Max Brake” pressure to number 2.
HELPFUL HINT! Setting the Brake Sensitivity to a higher number means you will need more force on the
RVs’ brake pedal to activate the braking system. Setting the Max Brake Pressure to a higher number
means the braking unit is exerting more pressure on the towed cars brakes.
14. PROGRAMMING LEVEL
Make sure the car is NOT running and it is on a LEVEL SURFACE. Also, verify that the unit is roughly
level. Adjust feet as necessary to level. If the compressor is running, wait for compressor to stop.
Now press and hold the “Max Brake” and “Brake Sensitivity” buttons simultaneously to program level.
This calibrates level and gives the unit a starting point for sensing deceleration. Once you have pressed the
“Max Brake” and “Brake Sensitivity” simultaneously, the row of lights for the “Brake Sensitivity” will flash two
times to let you know that the unit’s level has been successfully programmed. Do not proceed until the
row of lights flashes or your braking system will NOT perform properly while towing.
IMPORTANT! You only have to program level one time during the original installation. The next time you tow,
you will not need to re-program level. The this unit remembers “level” even after being unplugged. The only
time you need to re-program level is if you change towed cars. If the system is not performing properly, it is
usually because “level” has not been programmed properly. In this case, re-program level as described above.
CAUTION:
!
Car must be roughly level. If the car is severely off level when you push
the Max Brake and Brake Sensitivity buttons simultaneously, it will make
the system too sensitive and cause it to brake at the slightest bump or
rough spot in the road. Always be sure the car is on flat ground and not on ramps, hoists or a hill
when setting level. This will help prevent unnecessary braking.
IMPORTANT:
!
Installation continued
17. Check for secure placement of the unit and seat. Do this by depressing the test button and holding it until
the cylinder extends. If it moves excessively, or interferes with seat position controls, adjust
positioning and retest. Adjustable seat pad may need to be readjusted after pressing and holding the
test button until the cylinder extends. Verify that it is not unlocking the seat, affecting seat position
controls, or allowing the braking system to “climb”.
HELPFUL HINT! Some rubberized floor mats will cause “climbing”. Remove the floor mat if this happens.
If the unit is repositioned for any reason, be sure to reprogram level as described in step 14, before
continuing.
This next step fully activates the unit.
Don't let the unit "climb". If the braking system's adjustable seat pad is not
properly positioned on the front of the seat, the unit can "climb" up the seat
with repeated braking. This will cause the rear of the box to raise up off the
floor making the braking system more sensitive. If this occurs, you will experience excessive &
unnecessary braking. Always push the test button and hold it until the cylinder extends after the
installation to make sure the unit is secure and stable & will not "climb" up the seat. If it does,
reposition the adjustable seat pad so that the unit cannot "climb". Failure to follow these instructions
will result in non-warranty brake damage.
CAUTION:
!

Installation of BrakeAway System
Determine if you will be using the included
BrakeAway System.
Visit www.roadmasterinc.com/laws.htm to see if
a breakaway is required in your state. Roadmaster
strongly recommends that you always use the BrakeAway
System even if it is not required in your state or country.
The BrakeAway kit is an integral part of the braking system
and should always be installed. Roadmaster strongly
recommends that you install and use the BrakeAway.
If you choose not to use the BrakeAway, Roadmaster will not be
held responsible for any property damage, personal injury or
liability that results.
a.) Mount the Breakaway switch to a metal surface (not plastic) on the car near the driver's side front of the vehicle. Make
sure that the mounting location can be easily accessed. The Breakaway switch must be installed in a horizontal
position that allows the Breakaway pin to point toward the motorhome. Be sure the install location allows the
Breakaway pin to pull freely away from the car without any obstruction.
Do not attach the Breakaway switch to the brackets or the tow bar. If the tow bar or
bracket fails, the BrakeAway will separate with the bar or bracket preventing the
Breakaway switch from activating.
WARNING:
!
HELPFUL HINT! If you install the Brake-Lite Relay Kit number 88400, your brake lights will not come on
unless the ignition switch is turned on. Therefore, always turn on the ignition switch when checking for
brake lights. Manually depress the brakes to verify the brake lights are working.
18 a.) Turn ignition on. Do not start the vehicle, but make sure that the ignition is in the "ON" position, NOT the
"ACCESSORY" position.
b.) Go to the rear of the vehicle and see if brake lights are on. If so, DO NOT TOW. You must reposition the
unit as its current position will cause the brakes to be on all the time. After repositioning, check the brake
lights again. Now reprogram level (see step 14).
c.) Now have someone push and hold the test button so that the Portable Braking System will activate. The
brake lights should come on. This step is just to verify that your brake lights are functioning properly.
IMPORTANT! The Brake Alert transmitter will alert you when the unit cylinder is extended, not
necessarily when the brake pedal is being depressed. The system includes Brake Pedal Monitor Kit #9333
will illuminate the transmitter when the brake pedal is being depressed regardless of if the cylinder is
extended such as when the seat is too far forward forcing the unit closer to the brake pedal.
Refer to “Brake Pedal Monitor Wire Kit #9333 installation instructions later in this manual.
Make sure the system is not depressing the brake pedal. If the unit is
positioned improperly, or if the seat is too close, then the system will cause
continual braking resulting is severe non-warranty brake damage. Once
installed, follow the steps below to make certain that the unit is positioned correctly.
WARNING:
!
Installation continued
b.) Start in front of the car on the driver's side. Carefully route the wire through the firewall using a pre-existing hole if
possible. If not, drill a 1/2" size hole. Cut the included grommet on one side and place around the wire and then
insert the included grommet in firewall. Feed the remaining wire through the grommet and carefully route the wire
through the engine compartment to the inside of the car where the wire is within reach of the Breakaway switch.
Avoid wire placement near moving parts or hot areas of the engine as this will cause non-warranty failure.
Seal grommet with silicone sealer (not included).

damage or injury.
CAUTION:
!
Do not forget to release your emergency brake before towing.
Non-warranty brake damage or brake fire may occur
CAUTION:
!
Plug BrakeAway wire into blue jack on the braking system after the unit has been properly installed in
car. Upon completion of the installation, test system by pulling pin out of Breakaway switch. The unit should
activate when pin is pulled.
Connecting Breakaway Cable
Clip the steel cable to the large ring on the Breakaway switch, then clip the other end of the steel cable to
the center rear of the motorhome. Always check the following:
a.) Connect the cable close to the center of the rear of the motorhome. Connecting the cable towards the sides
of the motorhome will cause the cable to activate the BrakeAway System when turning sharp corners.
b.) Be sure there are no obstructions that would prevent the cable from freely pulling away from the Breakaway switch.
DO NOT WRAP THE CABLE AROUND ANY COMPONENT. DOING SO COULD KEEP THE CABLE FROM PULLING
THE PIN PREVENTING THE BRAKEAWAY SYSTEM FROM ACTIVATING.
c.) Make sure the cable is long enough to prevent the Breakaway pin from being pulled out during
normal towing. Also, remember that if you have a telescoping tow bar, you must allow enough slack so that the
tow bar can fully extend. If the cable is too short, the BrakeAway System will activate even though the car has
not broken free.
d.) Be sure the cable is not too long. It should not hang way down or drag on the ground. This much slack
could allow the cable to get caught going through dips or low spots causing the BrakeAway System to activate.
e.) Do not remove the Breakaway pin. This will activate the BrakeAway System and result in a dead battery.
Only remove the pin to test for proper BrakeAway System operation.

lights must be able to function with ignition key in towed position.
Some vehicle’s brake lights ONLY function with ignition system
turned on. If this occurs, a separate 2 prong stop light switch and
10 amp fuse must be installed and custom fit to operate monitor kit.
This stop light switch is not supplied and is available at local
automotive parts stores.
First install the Brake-Lite relay kit as described in the section
titled “Optional Brake-Lite Relay Kit”. To install the Monitor
wire kit, connect the monitor wire using the included yellow

Installing BrakeAlert System
IMPORTANT! RECEIVER MUST BE LOCATED SUCH THAT THE DRIVER CAN EASILY VIEW THE LED
INDICATORS ON THE RECEIVER IN THE MOTORHOME.
HELPFUL HINT! The Receiver will normally get a
stronger signal closer to the driver’s side window.
It is not necessary to secure the Transmitter with the
included Velcro; however, if you do, be sure to test
the system for proper signal strength. Some mounting
locations (for BOTH the Transmitter and Receiver) will
afford a better signal than others. For testing
purposes, be sure the car is connected to the
motorhome with the RV’s engine running while
checking reception.
HELPFUL HINT! When choosing a mounting location
for your antennas, never point them at each other as
you will not get good reception. See figure 3.
HELPFUL HINT! Many electrical components generate electrical interference. Before mounting your
Transmitter and Receiver, turn on all large electrical components (such as generator, motorhome engine and
roof air conditioner) to verify you are receiving a signal in the RV.
IMPORTANT! Do not route transmitter and/or receiver wires parallel to antenna as shown below or a false
signal may result.
19. Install the Receiver in the motorhome and plug into 12 volt
outlet. In order to ensure a secure power cord connection, use the
included cord lock. Follow figure 2a through 2c shown earlier in the
manual to properly use the cord lock. Now, install the Transmitter in
the towed vehicle and plug into the Red and White RCA jacks on
the braking system unit.
HELPFUL HINT! The Receiver’s yellow light will illuminate
briefly to verify the Receiver is getting 12 volts.
20. INSTALLATION IS NOW COMPLETE. As a safety precaution,
drive RV and towed car and test system for proper operation.
Check brake lights on towed vehicle to verify that your braking
system is not depressing brake pedal except when braking.

BrakeAlert operation
The BrakeAlert monitor system is
designed to communicate the
braking status of the unit. Red
light staying on means the brakes on your towed
vehicle are on. If the red light stays on even when
you are not braking and does not go off, immediately
stop and investigate. DO NOT continue to tow until the
problem has been corrected. Failure to do so will
result in significant brake wear, damage or even a
possible fire in your towed vehicle. Towing in this
fashion voids warranty and will result in non-warranty
property damage.

Make sure the cord to the BrakeAlert system is routed so that it cannot get entangled
with the steering wheel as it turns. This may result in property damage or injury.
CAUTION:
!
The Receiver simply monitors for a transmission from the unit and communicates to you with its LED lights.
During normal use, the red light on the Receiver will illuminate whenever the braking system activates. Following
are the various light codes and what they mean:
1. If red light is on -
The brakes on your towed car are on.
2. If red light repeatedly flashes and does not stop -
This is your low battery alarm. Your braking system has gone into sleep mode to prevent further
depletion of your towed car’s battery. Your battery needs to be charged.
The system monitors the battery voltage in your towed car. If the voltage starts to drop too low, this light will
continually flash to let you know that your towed car’s battery is going dead. This feature usually gives you the
opportunity to start your car before it’s too late. To turn off this alarm, simply charge the battery and re-plug in
the unit.
HELPFUL HINT! In addition to the red monitor light flashing, the red lights on the unit will also flash to remind you
that it is in sleep mode and that the braking system is no longer functioning for normal braking. However, the
system will still activate if a brakeaway should occur during the sleep mode.
HELPFUL HINT! Depending upon the condition and age of your battery, you will typically get 2 to 3 days of towing
before your battery goes dead. We recommend recharging your towed cars battery each day after towing.
Alternatively, you can route a charge line from the coach to the towed car that will continually charge your towed
car’s battery.
HELPFUL HINT! To wake your unit after recharging your battery plug the braking system back into a 12 volt outlet.
Receiver
Part #650990
Do not leave your car running while towing as this will allow your power brakes to
function. This unit is designed to work with a dead pedal. The power brakes will
cause excessive braking in the towed car resulting in significant brake and tire
damage not covered by warranty. If for any reason you must have the towed vehicle running while
being towed, it is imperative that you disconnect the System.
WARNING:
!
Your braking system will not function when in the sleep mode and you will not
have the additional stopping power. You must take this into consideration if you
choose to continue towing.
WARNING:
!

The Receiver and Transmitter are coded alike at the factory for proper communication. Normally, you would
never have to recode your Receiver. However, we have included the following instructions in case you ever lose
your Receiver or Transmitter and have to replace it with a new one.
1. Push the reset button until the yellow light comes on (about 5 seconds). Be sure to release the button once
the yellow light comes on. The red light will also flash every 5 seconds.
2. Have someone go to the towed car and activate the braking system by depressing the test button and
holding it until the cylinder extends. This will cause the Transmitter to send the code to the Receiver. Keep
the test button depressed. Hint: If you have an additional 12 volt outlet in the car, you can take the
Receiver with you to the towed vehicle and perform the above instructions. If you do not have an additional
12 volt outlet you can purchase our optional 12 volt “Y” part number 9330.
3. While the test button is depressed on the unit, press and release the reset button on the Receiver
several times until the red LED light illuminates. The Receiver is now programmed to match the
Transmitter’s code.
Recoding BrakeAlert
BrakeAlert Transmitter
The Transmitter simply relays braking information up to the Receiver in
the motorhome. The red LED on the Transmitter will illuminate each time
a signal is sent to the Receiver.

2. Turn on the motorhome and activate your turn signal. The turn signal on the towed car should blink on and
off. Leave turn signal flashing for now.
3. Go to the towed car and depress the brake pedal.
4. If depressing the brake pedal deactivates the turn signal on the towed car, you need to install the
Brake-Lite Relay Kit number 88400. This kit will prevent the towed car’s brake lights from overriding the
turn signals. Refer to optional Brake-Lite Relay Kit instructions later in this manual.

Normal Operation
This braking system is designed to brake your towed car whenever it senses deceleration from your RV. Under
normal circumstances, the unit will activate whenever your RV is decelerating faster than your towed car (that is,
you are stopping your RV). If you are riding your foot on the brakes of the RV, then the braking system will not
activate because the RV is not slowing more quickly than the car. Similarly, when you come to a full stop, the
system will release since there is no longer any deceleration. The system will activate whenever it senses decelera-
tion in the RV. The unit consumes battery power in your towed car as you drive. Roadmaster recommends that you
start your towed vehicle after towing for more than 6 hours and let it idle 15 to 20 minutes to re-charge your battery.
To make sure your battery is re-charged, make sure your low battery light on the towed vehicle is not lit.
IMPORTANT! Battery conditions such as age or capacity will affect usage, time, and time to recharge.
How to remove the braking system
1. Unplug 12 volt power cord.
2. Unplug monitor and BrakeAway wires.
3. Press air relief.
4. Slide seat to rearmost position.
5. Detach clamp from brake pedal by pushing on the lower edge
of the release tab or pulling the top of the release tab towards
you which is located on the left of the clamp as seen in
figure 4, and lift the unit out of vehicle.
6. Wrap 12 volt cord onto cord holder.
7. Transmitter and Receiver can be left in place or stored.
8. Be sure BrakeAway cord is safely secured so that it cannot become entangled while driving vehicle.
9. It is okay to remove Breakaway cable; however, do not remove the Breakaway pin as:
a.) Dirt will accumulate in Break Away switch possibly causing unwanted activation or preventing proper
operation of Break Away.
b.) Failure to reinsert pin before installing the braking system unit will cause unwanted activation, potentially
causing injury or property damage.
CAUTION:
!
Do not tow with your towed vehicle’s engine running. This will energize the power brake
system and cause severe braking, resulting in non-warranty brake damage.
CAUTION:
!
Never leave Breakaway pin out of Break Away switch. Failure to reinsert pin
before installing the unit will cause unwanted activation, potentially causing
injury or property damage.

Troubleshooting
There are a wide variety of symptoms that can be related to something as simple as a blown fuse. The braking Unit, the
Receiver, and the Transmitter each have their own fuse built into the end of the power cord. Simply unthread the ring at
the end of the plug to remove the fuse. Be careful not to lose the spring inside. See figure 5.
12 volt plug Spring Fuse Screw cap
Symptom: The red light on the system continually flashes and does not stop.
Solution: This is your low battery voltage alarm. Please refer to the section titled “Brake Alert Operation” to see
what this means and what to do.
Symptom: Red light flickers over rough terrain or when not braking.
Solution: a.) Whenever the RV decelerates, the Unit’s module board will call for braking and send a signal to
the Receiver in the motorhome causing the red light to illuminate. As a result, you may see the red light
flicker on and off as you go over bumps and potholes (when not braking). It is important to know that
when the red light flashes momentarily, that your brakes are NOT yet activated. In this case, the system
anticipated braking, but then stopped calling for brakes as the deceleration immediately went away.
In short, it is possible for the red light to flicker over rough terrain or slow deceleration, and that this is no
cause for concern as your brakes are not actually depressed unless the red light stays on longer than
momentarily.
b.) If the light is flickering too often, increase sensitivity setting by 1 to make the system less sensitive
to rough terrain. It is important to note however, that the Unit may require more than light stopping
before it will activate.
Symptom: The yellow light remains lit on the Receiver and the red light flashes every 5 seconds or so.
Solution: The reset button on the Receiver has been depressed too long causing the Receiver to go into the
reprogramming mode. This can usually be resolved by unplugging the Receiver. Reconnect and test for proper
operation. If the Receiver is not getting the signal from the Transmitter, then you will need to reprogram the
Receiver as outlined in the section titled “Recoding BrakeAlert”.
Symptom: My Unit will not fit properly in my vehicle.
Solution: On some vehicles (such as the Jeep Liberty) the door jamb curves in sharply at the bottom restricting the floor
space required for the Unit, In this event, you may be able to raise the feet on the unit to gain adequate clearance.
An additional one inch of height can be gained by using Roadmaster’s optional feet extenders part number 9337-4 (set of 4).
Symptom: The test button is being depressed by the dashboard, it’s too close to the dash.
Solution: In order to alleviate this problem you need to adjust the position of the unit. Do this by:
a.) Lowering the braking system by threading the feet into the unit.
b.) Lowering the braking system further by removing the feet from the unit.
c.) Installing optional cylinder arm extender part number 9336 (1.5 inch) or 9336-3 (3.5 inch)
to allow the unit to sit farther back from the dash board and still reach the brake pedal.
Symptom: The pedal clamp does not fit my brake pedal securely.
Solution: Use a pair of channel locks or pliers to bend the five tabs of pedal clamp assembly to better fit pedal.
Contact Roadmaster in the rare event that your pedal clamp cannot be made to fit your brake pedal. Please have make,
model and whether transmission is manual or automatic when calling Roadmaster.
Symptom: Air cylinder will not extend to connect to pedal clamp.
Solution: Air cylinder is full of air which will not allow pedal clamp to extend. Release air by holding air relief button.

Troubleshooting continued
Symptom: The brake pedal clamp on the braking system comes into contact with the unit housing.
Solution: Brake pedals that are somewhat horizontal cause the pedal clamp to tilt. This angle causes the pedal clamp
to interfere with the unit housing when it retracts. Use optional pedal extender part number 9336 (1.5 inch) or 9336-3
(3.5 inch) to gain additional clearance from the housing.
Symptom: Nothing happens after proper installation.
Solution: a.) Check fuse on the end of power cord. The braking system unit uses a 20 amp fuse and the BrakeAlert
uses a 10 amp fuse.
b.) Check power at 12 volt outlet with key in towed position. If there isn't any 12 volt power you will need
an optional 12 volt power outlet (part number 9332).
c.) Polarity on 12 volt outlet kit has been crossed. Positive is connected to ground and ground to positive.
This will blow the 20 amp fuse in the end of the 12 volt power cord. You will need to correct the wiring and
replace the 20 amp fuse in the end of the power cord.
Symptom: Braking system is not running.
Solution: Check for red LED light on cigarette plug. Check fuse for towed vehicle. Also, check your battery voltage. If your
battery does not have sufficient power it will put the unit into sleep mode, always make sure your battery has full power.
Symptom: As soon as I plug in the braking system, the compressor starts cycling on and off and the air
cylinder starts pumping in and out (“jack-rabbiting”).
Solution: Simultaneously press and hold the “Max Brake” button and “Brake Sensitivity” button until the row of sensitivity
lights flash three times. This will program level and eliminate the symptom. If the box is not attached to the brake pedal and
in position for towing, then you will have to re-program level again once the box is properly in position. See section titled
“Programming Level” for more details.
Symptom: Braking system’s air cylinder jack rabbits (extends and retracts) repeatedly.
Solution: a) Vehicles wiring is too small or low in power for the unit to operate properly. The braking system requires 15
amps to function properly. Install optional 12 volt power outlet (part number 9332) to supply sufficient power
to the system.
b) This unit needs to be re-programmed for level. See section titled “Programming Level”
Symptom: Towed vehicle seat moves after the braking system depresses the brake pedal.
Solution: The unit may cause the seat to move. To avoid this, make sure the seat is in a locked position when it
is adjusted behind the system’s housing. Readjust the adjustable seat pad and re-test. Depress the test button and hold it until
the cylinder extends to check for proper position and seat stability.
Symptom: The unit rides up the seat.
Solution: Remove the floor mats under the braking system and/or check the position of the adjustable handle.
The handle also serves as an anchor point to keep the unit down as it depresses the brake pedal.
Symptom: Braking system is activating before I want it to, or when I don't think it should be.
Solution: a) Check for level of the unit in the towed car. If level, raise sensitivity number by 1.
b) Reprogram level as described under section “Programming Level”
Symptom: My brakes are applying when they should not be.
Solution: a) Reprogram level as described under section “Programming Level”.
b) The braking system may activate even when you are not depressing the motorhome’s brakes.
This is usually a result of an incorrect sensitivity setting. If you are experiencing unwanted
activation while going down steep grades, increase the number on the Brake Sensitivity to make
the unit activate to your preferences. Jake Brakes and Pac Brakes (that is engine braking
systems) may also cause unwanted system activation which can be solved the same way.
IMPORTANT! THIS DECREASED BRAKING SENSITIVITY SETTING MAY PREVENT THE SYSTEM
FROM ACTIVATING DURING NORMAL LIGHT BRAKING CONDITIONS.
FAILURE TO INSTALL AND OPERATE THE BRAKING SYSTEM AS INSTRUCTED MAY RESULT IN
UNIT TO MALFUNCTION, PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

Symptom: Towed vehicle's fuse for 12 volt outlet keeps blowing.
Solution: Check towed vehicle's fuse size. The braking system uses a 20 amp fuse. If towed vehicle’s is not sufficient,
install optional 12 volt power outlet (part number 9332). If fuse is of sufficient size, unplug BrakeAway from the unit to see if
fuse stops blowing. If so, you have a short in the BrakeAway wiring harness. Inspect wire for possible grounding and repair.
Symptom: The BrakeAlert system is not working.
Solution: Verify that all RCA plugs are connected to the correct jack: red to red, white to white, blue to blue. Check for
red LED light on Transmitter in towed vehicle (should illuminate each time the system activates). Check fuse in the end of the
12 volt power cord for the unit, Transmitter & Receiver. Also, make sure the antennas on both the transmitter & receiver are
not parallel to the power cords or near any other wiring or power sources as this may interfere with the BrakeAlert system.
Symptom: Red light on power cord is not illuminated when plugged into towed vehicle's 12 volt outlet.
Solution: a) Some vehicles do not have power unless vehicle is running. Start towed vehicle to see if you now have
power. If so, install Roadmaster optional 12 volt power outlet (part number 9332).
b) Check fuse for 12 volt outlet.
c) Check fuse in end of the braking system 12 volt plug.
Symptom: Brake lights on towed vehicle are overriding turn signals.
Solution: May need to use optional Brake-Lite Relay Kit part number 88400. See “Brake-Lite Relay Kit” towards the
rear of the manual.
Symptom: The compressor comes on when the system is plugged in, but not actually being
used for braking.
Solution: The system’s compressor will activate about every 10 minutes due to normal air dissipation. If compressor
activates repeatedly within a ten minute or less period (when not braking), contact Roadmaster Inc., you may have an air leak.
Question: How do I increase brake power?
Answer: Push the Max Brake Pressure button to select a higher number. Setting 1 being the least braking and setting 4
being the greatest.
Question: How do I decrease brake power?
Answer: Push the Max Brake Pressure button to select a lower number.
Symptom: After towing there is excessive brake dust on wheels on towed vehicle.
Solution: Decrease Max Brake Pressure setting by 1 number.
Symptom: After towing there is an unusual odor coming from the brakes on towed vehicle.
Solution: Decrease Max Brake Pressure setting by 1 number.
HELPFUL HINT! Setting the Brake Sensitivity to a higher number means you will need more force on
the RV brake pedal to activate the system. Setting the Max Brake Pressure to a higher number means the
braking unit is exerting more pressure on the towed vehicle’s brake pedal.

Use this “Y” to connect more than one 12 volt accessory to a single 12 volt outlet.
This easy-to-install kit prevents the brake signal from over-riding the turn signal of a towed
vehicle. It is necessary to install this kit on many vehicles with add-on braking systems that
depress the car’s brake pedal and will not interfere with the car’s electronics when the ignition
is on. See “Brake -Lite Relay Kit” install instructions later in this manual.
Kit includes:
• All wires and components needed • Easy to follow instructions

How to install optional 12 volt, 20 amp power connector #9332
Some models of cars have no power to the cigarette lighter when the ignition key is in towed position. This braking
system cannot operate without power. Also, some cars do not have the required 15 amp power supply for the cigarette
lighter outlet. The following are instructions on how to install the number 9332 kit in order to provide the braking unit with
a new full time 12 volt, 20 amp outlet.
1. Inspect the towed car's fuse panel with a test light. Some of the fuses will have power all the time, while others
will only have power when the ignition is turned on. Find an ATC type fuse that has power with the ignition off.
Pull the fuse.
2. Determine which side of the fuse terminal is "HOT". The "HOT" side will have power to it all the time.
3. Pull the fuse and install the fuse tap on the “HOT” side of the fuse as shown in Fig. 7. With the towed car’s ignition
off, replace the fuse into the socket. Make sure to crimp the fuse tap securely to the fuse blade. Use spade terminal to
connect cigarette outlet to fuse tap. Connect the ground wire to chassis with the screw provided.
Do not connect the fuse tap to the cold side of the fuse socket. If the towed
vehicle’s fuse blows, the braking system will not function and you will have no
brakes on the towed vehicle while towing.
WARNING:
!
CHECK 12 VOLT OUTLET BEFORE PLUGGING IN SYSTEM. Verify that the
wire with the ring terminal is connected to ground while the wire with the fuse
is connected to the fuse block. If the positive and negative wires are reversed, the 20 amp fuse in
the end of the 12 volt power cord will blow.
CAUTION
!
Failure to install inline fuses as shown in Fig. 8 will result in electrical fire,
property damage, personal injury or death, which Roadmaster will not be held
liable for.
WARNING:
!
Install the fuse tap on the side of the fuse
that will be plugged into the “HOT” side of
the socket & install into the fuse box. Make
sure to crimp the fuse tap securely to the
fuse connection.

Optional Brake-Lite Relay Kit (part #88400)
CAUTION:
DO NOT USE BRAKE-LITE RELAY ON ANY FORD THAT HAS A “NEUTRAL TOW
KIT”. USE OF THE BRAKE-LITE RELAY MAY PREVENT DISENGAGEMENT OF
THE TRANSMISSION FOR TOWING, CAUSING SEVERE NON-WARRANTY
TRANSMISSION DAMAGE. For all vehicles that have a Ford “Neutral tow kit” either use the
Brake-Lite solution on the following page or install Roadmaster’s Bulb & Socket kit #155.
Installation Instructions
1. Locate the towed vehicle’s brake
light switch. Cut the cold side of
the brake light wire a few inches
downstream from the brake light
switch. CAUTION: Verify that you
have the correct wire. When
the wire has been cut, with the
key in the “on” position, put your
foot on the brake. If the brake
lights remain on, you’ve cut the
wrong wire. Once you have
located the correct wire, install the Brake-Lite Relay in line as shown in Figure 9.
WARNING: Make sure that you install the 10 amp fuse assembly within 6” of the power source.
With Brake-Lite Relay Kit installed, the towed vehicle’s brake lights will ONLY function when
the towed vehicle’s ignition is ON.
!

Brake Light Solutions
IMPORTANT! Depending on how your towed car is wired for lights, it is possible that the brake lights will
override the turn signal. This occurs when the brake light power (from the towed car) overrides the turn signal
power (from the motorhome). In short, the towed car is trying to flash the turn signal, but the power from the
brake keeps the bulb illuminated preventing it from flashing. You can solve this by adding the Brake-Lite Relay
Kit number 88400 or by adding additional wiring diodes to your towed car. Detailed instructions for both
solutions follow. Alternatively, you can install Roadmaster’s bulb and socket kit #155.
2. Using fuse tap, connect the blue wire from the
Brake-Lite Relay to the “HOT” side of any fuse
which is powered ONLY when the towed car’s ignition
is turned on. NOTE: The “HOT” side of the socket is the one that registers voltage when the fuse is
pulled, the ignition switch is on and tester is connected between the socket and ground.
3. Connect the black wire to any good chassis ground.
4. Secure the Brake-Lite Relay and wiring harness using enclosed zip ties.
5. Test System: a. When the car is running, the brake lights will function normally.
b. When car’s ignition is off, brake lights will not function.
NOTE: Do NOT drive your vehicle if the brake lights are not functioning normally.

Combined Brake / Turn Light System
The brake light does the flashing
for the turn signal
Separate Brake / Turn Light System
There are amber or red turn signals
which are separated from the brake lights
Use two optional diodes and wire as shown in Figure 10. When wired properly, both the turn signal and brake
light will flash when the turn signal is on. However, when the brake & turn signal is on, the brake light will stay
illuminated while the turn signal flashes. If the turn signal on the towed vehicle stays on when the brake pedal is
depressed, then you will need the Brake-Lite Relay Kit number 88400.

7.ADDRESS FOR NOTICES TO ROADMASTER : ROADMASTER, Inc., 5602 N.E. Skyport Way, Portland, OR 97218
This warranty gives you specific legal rights, and you may also have other rights which vary from State to State.
Failure to release emergency brake on towed vehicle before towing will result in severe brake damage or brake fire and is not covered by
warranty. It is important to note that the BrakeAlert monitor system will NOT illuminate when your emergency brake is on.
Do not leave your car running while towing as this will allow your power brakes to function. This unit is designed to work with a dead pedal.
The power brakes will cause excessive braking in the towed car resulting in significant brake and tire damage not covered by warranty. If for
any reason you must have the towed vehicle running while being towed, it is imperative that you disconnect the braking system.
WARNING! The BrakeAlert monitor system is designed to communicate the braking status of the braking unit. Light on means your brakes
are on. If the light stays lit even when you are not braking the RV, immediately stop and investigate. DO NOT continue to tow until the prob-
lem has been corrected. Failure to do so will result in significant brake wear, damage or even a possible fire in your towed vehicle. Towing in
this fashion voids warranty and will result in non-warrantable property damage.
All illustrations and specifications contained herein are based upon the latest information available at time of publication. ROADMASTER, INC. reserves the
