GETTING STARTED
Thank you and congratulations on your purchase of a Pacbrake exhaust retarder.
Before starting the installation, please read the entire installation manual carefully and be sure you have a full
understanding of the installation. Check that your Pacbrake kit is correct for the application and contains all the
necessary parts shown in the photo below.
C40010 - Manual Shift Transmissions
C40007 - Automatic Shift Transmissions
Note: The kits listed above are for vehicles with stock
exhaust. If you have aftermarket 4"exhaust you will
need to order two exhaust adapter part # C11342
KIT CONTENTS (C40010)
KIT CONTENTS (C40007)
A ½ gallon air tank is supplied to speed up the actuation
of your Pacbrake and provide an air source for limited
accessory use. Also provided is a 5 in 1 inline ination/
deation kit with a 25' coil hose with zippered storage bag.
Please note: The air compressor has a 33% duty cycle,
this is well above the exhaust brakes requirement.
Caution must be exercised when using the compressor
and ination kit for other uses. Please consider the air
compressor’s duty cycle when continually in use for
more then 3 minutes, failure to do so may allow the air
compressor or hoses to overheat causing failure.

EXHAUST BRAKE INSTALLATION
22003 Model Year Vehicles
Early production Ford trucks have a pre-cat installed in the
forward section of exhaust pipe. An alternate location for
exhaust brake installation is in the straight section of pipe
before the header pipe ange. Measure 3" forward from
the front side of the header pipe ange and mark the pipe,
then measure 6" forward from the rst mark and mark the
pipe. Remove the header pipe to cut at the two marks.
The transmission cross member will need to be removed
to allow the removal of the header pipe for welding. Pro-
ceed to step 5.
32004 M/Y and Newer Vehicles
A 6" section of exhaust pipe must be removed to accom-
modate the exhaust brake and adapters. From below the
vehicle, measure from the front side of the header pipe
ange forward 23" and mark the pipe. Then measure and
mark the pipe 6" back from the rst mark. See photo.
42004 M/Y and Newer Vehicles
Cut the exhaust pipe at the two marks. Cutting the pipe in
the vehicle will eliminate removing the transmission cross
member.

5Using the “V” clamps and adapters provided, loosely
install the adapters onto the Pacbrake - making sure they
are centered on the anges and tight enough that they can
not move prior to being welded. Please note the direction
of exhaust ow through the exhaust brake as shown in
the photo and the sticker on the exhaust brake. Tack weld
the anges to the exhaust system to secure, then remove
the “V” clamps and exhaust brake for nal welding of the
anges. Welding can be done on the inside or the outside
of the pipe, they must be leak free welds. Install the 90
degree tting into the air cylinder using thread sealant.
6Re-install the exhaust system. Loosely install the factory
turbocharger “V” clamp, but do not fully tighten the turbo-
charger “V” clamp at this time (if the exhaust system was
removed for welding). Install the front “V” clamp onto the
exhaust brake ange and adapter with the PRXB regulator
spring located inside the frame rail, make sure the exhaust
brake is centered on the adapter. Torque the “V” clamp to
10 ft-lbs, (14 N•m). Then, loosely install the rear “V” clamp
onto the exhaust brake ange and adapter. (If the header
pipe was removed for welding) center the header pipe
ange to the turbocharger ange, torque the factory “V”
clamp to 72 in-lbs, 6 ft-lbs, (8 N•m). Ensure the exhaust
system is aligned correctly (ange centered) and that ad-
equate clearance exists around the exhaust brake. Then,
torque the rear “V” clamp to 10 ft-lbs, (14 N•m).

12 Locate the vacuum pump electrical connector disconnect-
ed in step 7. Cut the two wires 4" back from the connector.
Using the lengths of black and green wire and the butt
connectors provided, extend the harness to enable the
connector to reach the new vacuum pump location. Once
the butt connectors are crimped, heat the connectors to
provide a moisture tight seal. Protect the harness with the
conduit provided and secure with tie-straps.
13 The Pacbrake air compressor mounting bracket mounts in
the same location the vacuum pump was removed from.
Insert the two supplied M8x40 capscrews and washers
through the bracket and then the two spacers. Shown in
the photo is the air compressor bracket, it needs to be
installed UNDER the foot for the vacuum reservoir. This
requires the nuts in the wheel well to be loosened enough
to lift the reservoir so the notch in the compressor bracket
can be inserted under the reservoir foot. Once the com-
pressor bracket is under the reservoir foot, loosely thread
the M8x40 capscrews into the inner fender. Tighten the
vacuum reservoir nuts and then torque the M8x40 cap-
screws to 13 ft-lbs (18 N•m).
Note: The notch in the compressor bracket must be
UNDER the vacuum reservoir foot.
14 Install the compressor on to the 3 mounting studs of the
bracket, secure the compressor using the supplied wash-
ers and nyloc nuts, torque to 35 in-lbs, (4 N•m). Connect
the hose from the tee tting of the pressure switch to the
compressor.

side inner fender in a pre-existing hole. The air intake ports
of the lter must point down. Connect the supplied blue ny-
lon hose to the barbed tting on the lter and the other end
to the 90 degree tting on the side of the compressor. The
air intake hose must not be restricted or poor compressor
performance will result.
NOTE: The remainder of the blue nylon hose will be used
in step 19.
17 Install the ttings in the top of the air tank using thread
sealant, as shown in the photo. Install the ¼" NPT plug
supplied, which will act as a drain valve, in the bottom of
the tank.
Choose a location on the outside of the frame to mount
the air tank with the supplied fasteners.
NOTE: Step 18 suggests using one of the air tank fasten-
ers as a good mounting location to mount the solenoid.
Consider this when choosing the air tank mounting loca-
tion. Use existing holes in the frame if possible. Connect
the airline from the pressure switch and air chuck assem-
bly installed in step 9, to either of the two ttings at the

Testing The System
Before starting the vehicle, ensure the Pacbrake ON/OFF switch is in the OFF position. Start the engine and allow to idle.
The Pacbrake air compressor should start to pump air and will pump for approximately 2 minutes until maximum air pressure
is acheived within the tank. The Pacbrake Control Unit will cycle the exhaust brake ON and then OFF 3 times to prevent carbon
build-up within the exhaust brake. The Pacbrake Control Unit monitors the following vehicle systems status and the exhaust
brake will not apply unless these parameters are met:
Activation Parameters For Manual Transmission Vehicles:
- engine RPM must be above 1200
- accelerator position must be at zero throttle
- vehicle speed must be above 19 MPH (30 KM/H)
- exhaust brake swtich must be in the ON position
Road test the vehicle ensuring all the activation parameters are met. With the Pacbrake switch ON, the exhaust brake should
apply then release when either the minimum road speed of 16 MPH (25 KM/H) is achieved or the engine RPM goes below 900
RPM or the accelerator is depressed.
Activation Parameters For Automatic Transmission Vehicles:
There are two options for torque converter engagement based upon vehicle speed. The controller is pre-programmed with both
speed options, and comes defaulted to the low speed setting. To change the mode, the Pacbrake switch and ignition must be in
the OFF position. Then, turn the ignition to ON, wait for the compressor to turn OFF, then the exhaust brake should cycle 3 times
performing it’s anti-foul cycle. Next, cycle the Pacbrake ON/OFF switch to ON, OFF, ON, OFF, ON and OFF with no pauses
longer than 1 second. This will change the mode. The exhaust brake should now cycle either 4 or 5 times. Count the number of
times - this will conrm the mode that has been selected (see below). Once the Pacbrake module has cycled the brake to con-
rm the torque converter engagement setting, it will then cycle 3 times at startup to perform the anti-foul cycle.
4 cycles = higher speed torque converter engagement setting is loaded
5 cycles = lower speed torque converter engagement setting is loaded
Road test the vehicle, ensuring all the activation parameters are met. With the Pacbrake switched to ON, the exhaust brake
should apply and then release when either the minimum road speed of 16 MPH (25 KM/H) is acheived or the engine RPM
goes below 750 RPM or the accelerator is depressed.
Low Speed Mode:
- engine RPM must be above 1200
- accelerator position must be at zero throttle
- in “tow/haul” mode the vehicle speed must be above 22 MPH (35 KM/H)
- in “overdrive” mode the vehicle speed must be above 22 MPH (35 KM/H)
- exhaust brake swtich must be in the ON position
Higher Speed Mode:
- engine RPM must be above 1200
- accelerator position must be at zero throttle
- in “tow/haul” mode the vehicle speed must be above 31 MPH (50 KM/H)
- in “overdrive” mode the vehicle speed must be above 31 MPH (50 KM/H)
- exhaust brake swtich must be in the ON position
Congratulations, you have completed the installation
WARNING - Do not operate the vehicle with the Pacbrake control unit removed or disconnected. If it is necessary, jumper wires
must be installed. Vehicles equipped with manual shift transmissions ADD jumper wires between Pins 1 & 2 and Pins 7 &8.
Vehicles with automatic transmissions ADD jumper wires between Pin 19 & 20, Pins 5 & 6, and Pins 7 & 8.
