• Maintain a safe working environment. Keep the work area well lit. Make sure there is
adequate surrounding workspace. Always keep the work area free of obstructions,
grease, oil, trash, and other debris. Do not use the Vacuum Pump in areas near
flammable chemicals, dusts, and vapors. Do not use this product in a damp or wet
location.
• Maintain labels and nameplates on this product. These carry important information. If
unreadable or missing, contact Performance Tool for a replacement.
• Keep the handles of the Vacuum Pump dry, clean, and free from brake fluid, oil, and grease.
• Prior to using the Vacuum Pump make sure to read and understand all warnings,
safety precautions, and instructions as outlined in the vehicle manufacturer’s
instruction manual. Every vehicle has specific measurement values for vacuum related
readings. It is beyond the scope of this manual to properly describe the correct
procedure and test data for each vehicle.

WARNING: Carbon monoxide is produced while a vehicle’s engine is operating and is
deadly in a closed environment. Early signs of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, or nausea. If you have these signs, the work area may not
be vented properly. Get fresh air immediately.
• Prior to using the Vacuum Pump, make sure to place the vehicle’s transmission in
“PARK” (if automatic) or “NEUTRAL” (if manual). Then, block the tires with chocks.
• Be alert for hot engine parts to avoid accidental burns.
• Avoid accidental fire and/or explosion. Do not smoke near engine fuel and battery
components.
• Use the Brake Bleeder only with brake fluid. Do not attempt to use the tool to siphon
any other liquids. Damage to the internal chamber and seal, or future brake fluid
contamination ma result.
• Follow guidelines for proper brake fluid disposal. Used brake fluid should be removed
from the vehicle and properly recycled. Many states require recycling. Contact your local
solid/liquid waste authority for information on recycling. Do not reuse old brake fluid.
• Brake fluid is corrosive. Avoid spilling it on the vehicle’s exterior, it can harm automobile paint.

WARNING: People with pacemakers should consult their physician(s) before using this
product on a running engine. Electromagnetic fields in close proximity to a heart
pacemaker could cause interference or failure of the pacemaker. In addition, people with
pacemakers should adhere to the following: Caution is necessary when near the coil, spark
plug cables, or distributor of a running engine. The engine should always be off if
adjustments are to be made to the distributor.

WARNING: Always release the vacuum in the Vacuum Pump before performing any
inspection, maintenance, or cleaning.
• Before each use: Inspect the general condition of the Vacuum Pump. Check for
misalignment or binding of moving parts, cracked or broken parts, damaged Hoses, loose
connections, and any other condition that may affect its safe operation. If a problem
occurs, have the problem corrected before further use. Do not use damaged equipment.

WARNING: The warnings, precautions, and instructions discussed in this manual cannot
cover all possible conditions and situations that may occur. The operator must understand
that common sense and caution are factors which can not be built into this product, but
must be supplied by the operator.
PRODUCT WARNINGS

5
NOTE: Measurements and illustrations are for reference only.
Your test results may vary.
NORMAL ENGINE
1. With the vacuum pump connected to an intake manifold
vacuum port.
2. Start engine, bring to normal temperature and let idle.
3. Look at the needle’s movement on the gauge. At idle,
the needle should read 16-22 in. of Hg and hold steady.
This is your base line, indicating everything
functioning normal.
WEAK OR BROKEN VALVE SPRING
• A sign of weak valve springs are when the pointer on the
vacuum pumps gauge fluctuates rapidly between 10 and 21
in. of Hg at idle. As the engine speed increases the
fluctuations will increase too.
• A broken valve spring will still cause the needle to fluctuate
rapidly at regular intervals. The difference can be seen every
time the cylinder fires and the valve attempts to close.
STICKING VALVE
• A valve that’s sticking will exhibit a rapid drop intermittently
from a normal pointer indication. This is because a sticking
valve or valves don’t always stick on each cycle of the
engine. To pin-point a sticking valve apply lightweight oil
directly to each valve guide using a syringe with a fine tip. As
the oil coats the guide the sticking valve will temporarily
function normal. The needle on the gauge will be steady until
the oil burns off.
BURNED OR WORN-LEAKING VALVE
• At idle, the pointer on the gauge will drop then return to
normal. This would happen at regular interval. Every time the
cylinder fires with the bad valve it will cause the needle to
drop to a low reading. The needle will drop from 1 to 7 in. of
Hg, then return to a normal reading.
WORN VALVE GUIDES
• A worn valve guide lets air into the cylinder, this changes the
air/ fuel mixture. The needle on the gauge will run lower than
normal, approx. 3 in. of Hg and will fluctuate rapidly. When
you increase the speed of the engine the needle will stop
fluctuating.
BLOWN CYLINDER HEAD GASKET
• At idle, the needle will fluctuate from normal to a low reading.
Each time the affected cylinder reaches firing position the
needle will drop sharply. You should see about 10 in. of Hg
drop from normal, then return.

INTAKE MANIFOLD LEAK
1. With the vacuum pump connected to an intake manifold
vacuum port.
2. Start engine, bring to normal temperature and let idle.
3. Look at the needle’s movement on the gauge.
• If you have a bad gasket, or cracked hose this could
cause air to leak into the intake system. If this happens,
the needle will read about 4 to 9 in. of Hg below normal,
and will remain steady.
EXHAUST GAS RECIRCULATION (EGR)
1. With the vacuum pump connected to an intake manifold
vacuum port.
2. Start engine, bring to normal temperature and let idle.
3. Note the needle’s movement on the gauge.
• The needle should read 16-22 in. of Hg and hold steady.
and will remain steady.
4. Increase the engine speed to approx. 2000 RPM.
• As the speed increases slowly, so should the vacuum.
This indicates the EGR valve is operating properly.
• If the needle drops, moving toward zero you have a
malfunctioning EGR valve.
• To test:
1. Remove the EGR valve from the manifold.
2. Connect your vacuum tester to the diaphragm on the
EGR valve.
3. Pump the trigger of your tester building vacuum. The
needle should not move and hold steady. If the
needle starts to drop, your EGR valve has a crack/
hole in the diaphragm.
TESTING PROCEDURES
LEAKING PISTON RING
• If you experience leaking rings the vacuum at idle will be low
with the needle holding steady between 12 and 16 in. of Hg.
1. To test open the throttle.
2. Increase the engine speed to about 2000 RPM.
3. Then close the throttle quickly and watch the needle of the
gauge. It should jump 2 to 5 in. of Hg above its lowest reading.
A lesser gain may indicate faulty rings, and a complete cylinder
leakage or compression test should be done.
IDLE AIR/FUEL MIXTURE
• A sweeping change of 4 to 5 in. of Hg back and forth at idle
indicates a rich fuel mixture. With a lean mixture the needle
will drop irregularly over about the same range.

EXHAUST GAS RECIRCULATION (EGR)
FUEL PRESSURE REGULATOR
ELECTRICAL /VACUUM SOLENOID

7
FUEL PRESSURE REGULATOR
NOTE: To verify a Fuel Pressure Regulator is functioning
properly you’ll need a Fuel Pressure Tester along with your
W87032 Vacuum Tester.
1. Do a visual check for leaks around the regulator or signs of
cracks or fuel in the vacuum line at the diaphragm.
• If you find a leak or fuel in the vacuum line replace the regulator.
2. Install the Fuel Pressure Tester to the rail.
3. Start the engine and bring it to temperature and let idle.
4. Disconnect the vacuum line from the fuel pressure regulator at the diaphragm.
• Looking at the pressure tester, the fuel pressure should have increased 10 to 12 psi.
If nothing changes the regulator or vacuum line is bad.
5. Confirm the condition of the vacuum line by connecting it to
the Vacuum Pump.
• The needle should hold steady at 16 to 22 inches of Hg.
• If you have a low, or no reading the vacuum hose is
plugged or bad.
6. Disconnect the Vacuum Pump from the vacuum
hose and plug it.
7. Attach the Vacuum Pump to the diaphragm on the
pressure regulator.
8. Apply vacuum to the regulator and watch the gauge of the Fuel Pressure Tester. The
fuel pressure should increase approx. one pound for every two inches of vacuum
applied to the regulator. If it doesn’t the regulator is bad and needs to be replaced
ELECTRICAL /VACUUM SOLENOID
1. Disconnect vacuums and electrical connectors,
make note of the hose locations.
2. With no power to the solenoid, attach the
vacuum pump to port “A”.
3. Apply vacuum, and watch the gauge.
• The vacuum should reduce to zero after each pump.
The vacuum is released through the other port, “B”.
4. Apply power to the solenoid by using alligator leads.
Ground the negative side to a good metal bracket or
frame. Add 12 volts to the positive side from the battery.
5. Now when you apply vacuum it should not bleed off, holding steady.
6. With the solenoid still connected to power, switch the hose from
your pump to the other side of the solenoid port “B”.
7. Now apply vacuum, again it should bleed of. This time through
the intake system.
THERMAL VACUUM VALVES
NOTE: Called different names depending on the make of vehicle:
GM - Thermal Vacuum-Switches (DTVS)
Chrysler/Jeep - Thermal Ignition Control (TIC)
Ford - Ported Vacuum Switches (PVS)
These two-port valves all have the same function, control
exhaust gases from recirculating. When the engine is cold
the valve should be closed.

1. Attach the vacuum pump to the bottom port and apply vacuum,
approx. 10 in. of Hg.
• The needle should hold steady and not bleed off.
If it does not hold, unit is bad and should be replaced.
2. Repeat the procedure after the engine has warmed to normal temp.
• As vacuum is applied it should bleed off to zero. If it
holds steady, unit is bad and should be replaced.
NOTE: These thermal switch are needed to provide good drive ability.
It limiting the entrance of exhaust gases until the engine is warmed
up. Depending on the vehicles make your thermal switch may have
more than two ports. You may have three or four ports, the end
function is the same. They control vacuum going to different
applications until the engine has warmed to normal operating temp.
Consult your service manual for the type used on your vehicle.

BRAKE BLEEDING INSTRUCTIONS
BENCH BLEED THE MASTER CYLINDER
Your new master cylinder will come with plugs in the outlet holes, leave them for now.
1. Gently clamp the unit in a vise using the mounting flange with the push rod end slightly
elevated. Do not clamp the master cylinder body or reservoir as severe damage will occur.
2. Fill the master cylinder three quarters full with the vehicles recommended brake fluid
type and, keep it filled at all times during the procedures.
3. Remove one of the plugs from the master cylinder and attach the proper adapter to
the outlet port. Connect the pump tube to the reservoir jar and the jar tube to the
adapter. Connect your vacuum pump to the pump side of the reservoir jar.
4. Operate the pump and observe air and fluid flowing into the reservoir until clear.
Continue pumping until a bubble-free fluid appears. It may take 4-5 pumps before that
circuit is full and free of air.
 CAUTION: Always use the DOT Brake Fluid specified for your vehicle, the most
common are listed below.
DOT3, DOT4, and DOT5.1 are glycol-based fluids, and DOT5 is silicon-based.
One difference is DOT3, DOT4, and DOT5.1 absorb water, while DOT5 doesn't.
Another important characteristics is, as the DOT number raises so does its boiling point.
Although DOT5 and DOT5.1 have similar boiling points, they CANNOT be mixed.
DOT5 is silicone based and DOT5.1 is glycol based and mixing the two will destroy the
seals in the brake system. DOT5.1 can be used as an upgrade or replacement for both
DOT3 and DOT4.
Anytime a brake system is opened to replace components such as calipers, wheel
cylinders, master cylinder, brake lines or hoses, air could get inside. This air must be
removed by bleeding the brakes to achieve a firm brake pedal. Any air trapped in the
lines, calipers or wheel cylinders will make the pedal feel soft and spongy when
depressed. Air is compressible, so any air bubbles in the system will be compressed first.
Then as you continue to apply the brakes, the hydraulic fluid transmits pressure to apply
the brakes. Air in the system takes away from your ability to apply full braking power.
DIAGNOSTICS
Trouble shooting an unknown brake problem, or doing a complete brake conversion or
rebuild. The first thing to look at is the master cylinder. Here are a few symptoms of a
faulty master cylinder.
• Spongy or Unresponsive: Brake pedal that doesn't produce the desired
stopping ability.
• Contaminated Fluid: As the seals inside of your master cylinder wear out,
the rubber crumbles and degrades, often resulting in visual contamination of the
brake fluid.
• Brake Drag: This happens when brakes are applied, but when released the piston
doesn’t return fully. Seals have failed and are holding the piston in the pressure position.
You’ve found that you have a faulty master cylinder, the first thing to do after getting the
replacement is bench bleed it. Once that has been completed and everything installed, then
bleeding off the rest of the system can be done. Bench bleeding the master cylinder is the
starting point. It’s simple and best done on the bench, out of the vehicle. There are several
ways to do the job, some involve special threaded adapters for the exit ports that use tubes
that return fluid to the reservoir. Another way is a special syringe that forces fluid through the
exit ports. Using the vacuum pump is the most natural way insuring all the air bubbles have
been removed, and the cylinder is getting completely filled.

5. Replace the plug tightly, move to the second outlet port and repeat the steps for the
second circuit. Be sure to replace the plugs tightly because hydraulic pressure will be
applied in the next step.
6. Now adjust the master cylinder in a vise with the push rod end down slightly. Slowly
push the master cylinder push rod in about a 1⁄8”, release it should return to its original
position. Repeat this several times until no air bubbles can be seen in the reservoirs. If
you master cylinder doesn’t have a push rod use a rounded piece of wood, or
something that won’t harm the push rod seat. Slotted and Philips screwdrivers seem
ideal, but can damage the seat or the rear seal.
7. Remount the master cylinder with the push rod end up slightly and repeat the bleeding
steps from above one more time. Plug both outlet ports tightly.
8. The master cylinder is now free of air and ready to install.
ANTI-LOCK BRAKE
Many newer vehicles are equipped with an Anti-Lock Brake System. Some of those could
include the use of a high pressure pump to keep the system pressurizes. Special
procedures are needed when servicing. Consult your service manual for those procedures.
Observe the following precautions when servicing Anti-Lock brake system:
• ALWAYS wear safety goggles when servicing high pressure brake systems.
• ALWAYS depressurize the ABS system prior to servicing, making repairs or adding fluid.
• NEVER loosen a hydraulic line or open a bleeder fitting while the ABS system is
pressurized.
• NEVER use silicone brake fluid in ABS equipped vehicles. Consult service manual for
brake fluids type.
• ALWAYS reference the manufacturer’s service manual for information on Anti-Lock
brake systems.
DEPRESSURIZING ANTI-LOCK BRAKE SYSTEMS
This procedure works on most Pressurized Anti-Lock brake systems. Always refer to the
appropriate service manual for manufacturer’s information on depressurizing procedure.
Ignition switch has been turned off, and the negative battery clamp has been disconnected.
1. First pump the brake pedal until a change in the peddle pressure is felt. This takes 25
or more pumps before a noticeable change is felt.
2. Pump the pedal a few more times, this will remove most system pressure.
3. Open the fluid reservoir or loosen brake lines, but still use caution. Leave the reservoir
off if you intend to change the brake pads prior to bleeding the brakes.
4. Top off the brake fluid with whats recommended for your vehicle.
5. Reconnect negative battery clamp when finished.
BLEEDING ANTI-LOCK BRAKE SYSTEMS
Bleeding the brakes after brake any components have been replaced is a step you don’t
want to skip. Air trapped in the lines, calipers or wheel cylinders will make the pedal feel
soft and spongy. Air is compressible, so any air bubbles in the system will get compressed
first. Then as you continue to apply the brakes, the hydraulic fluid transmits pressure to
apply the brakes. Typically the front brakes on most Anti-Lock brake systems can be bled in
the usual manner. Some automotive manufacturers use bleeding procedures which require
specialized equipment. Always reference the manufacturer’s service manual for the proper

brake bleeding procedure. If the only components you replaced were downstream of the
ABS modulator, chances are normal bleeding procedures will clear the lines of any
unwanted air. Components such as the calipers, wheel cylinders, brake hoses or lines,
these are downstream. The most common bleeding procedure is to bleed the brake furthest
from the master cylinder first, passenger rear. Then follow the brake line to the other brake
that shares the same brake circuit. Typically it’s the rear brake on the driver’s side of most
cars and trucks. Sometimes it’s the opposite front brake on a front wheel drive car or
minivan.
Always refer to the vehicle manufacturer’s recommended bleeding sequence as this may
vary from one application to another depending on how the system is configured. Then
bleed the other brake circuit starting with the furthest brake from the master cylinder. If the
repair involves replacing the master cylinder, a brake line or valve ahead of the ABS
modulator. Or, if replacement of the modulator or high pressure accumulator was needed.
This is where the vehicles service manual becomes a necessity. Some ABS modulators
have special bleeder screws to help vent the air when bleeding the system. Others don’t
and require an OBDII scan tool to cycle the ABS solenoids while you bleed the system.
BRAKE LINE BLEEDING
Most low and soft pedal problems are caused by air in the hydraulic lines, wheel cylinders
and calipers. The solution requires bleeding of the hydraulic brake system. By using the
pump with brake bleeding accessories, the system can be bled easily in a short period of
time. The vacuum pump kit provides a simple, clean, and quick method for bleeding the
fluid lines in the automotive brake system.
The order on most cars is starting with the passenger rear brake first, then driver rear, then
passenger front and finishing with the driver front. All bleeding fittings must be clean prior to
beginning the bleeding procedure. Dirt or contaminates can enter an open bleeder valve.
Be sure to check the brake fluid level in the master cylinder after bleeding each brake.
Don’t let fluid drop below the indicator line inside the reservoir. The vacuum pump creates a
vacuum as you pump the handle, causing fluid to be drawn into the reservoir. Tiny bubbles
may form in the hose after the air is bled from the lines. This air is seeping around the
threads of the loosened bleeder fitting as you pump the trigger of the vacuum pump. Fill the
master cylinder reservoir with new, clean brake fluid. Be sure to have plenty of the proper
DOT type for your vehicle handy. Keep the lid on, but close by to top off the reservoir after
bleeding each wheel.
NOTE: Follow manufacturer’s recommended bleeding sequence (if known). Begin at the
corner furthest from the driver and proceed in order toward the driver. (Right rear, left rear,
right front, left front.) While the actual sequence is not critical to the bleed performance it is
easy to remember the sequence as the farthest to the closest.
VEHICLE BLEEDING PROCEDURE
1. Find the wrench that fits your bleeder fitting on the caliper. Longer box end wrenches
work best for this. They help prevent stripping of snapping off the fitting. See
Performance Tools W80616, W80617, W80619, or W80620.
2. Place the wrench on the brake bleeding fitting. Select and press the adapter over the
top of the fitting.
3. Pump the handle several times, open fitting slightly watching for clean brake fluid and
fewer bubbles. It only takes about a 1/4 turn for fluid to flow into the jar. The vacuum
created should draw brake fluid as soon as the bleeder valve is opened. If it’s not,
make certain the lid of the jar is tight. Vacuum cannot build if the lid was not replaced

securely. Additionally it’s possible to have dirt in the bleeder valve. When that
happens you won’t be able to build the adequate amount of vacuum for the pump to
work efficiently. Road grime could’ve solidified inside the bleeder valve. If this happens
open the bleeder valve, have a helper apply pressure on the brake pedal slowly. At the
same time pump the handle of the vacuum pump. The build of pressure should clear
any debris that could’ve been plugging the valve. Be cautious not to over fill the
pumps reservoir jar. You do not want brake fluid reaching the vacuum pump, the fluid
will damage the seals.
4. After expelling about 3 oz. into the jar, close the fitting.
WARNING: NEVER remove the jar lid before releasing the vacuum in the vacuum pump.
5. Empty the jar, check for any dirt or debris before replacing the lid on the jar. Check the
master cylinder, add fluid if needed.
6. Reopen fitting and continue until all air is extracted.
7. Repeat these steps on all remaining wheels. Pay attention to the fluid level in the
master cylinder.
8. When complete, continuing to draw vacuum, tighten bleeder fitting.
9. When bleeding is complete pump the brake pedal several times. Pedal should have a
positive, solid feel. If not, inspect lines and calipers to ensure all fittings are tight. If
brake still feels slack, repeat bleeding process.
MOTORCYCLE BLEEDING PREPARATION - FRONT
• The brake caliper piston must not be seized. The pistons must be free to move within
the calipers.
• The master cylinder piston must not be seized. Piston must return to end of its stroke
when released.
• Inspect brake lines for cracks or wear, and that all fittings are tight.
• Cover any painted surface near the brake master cylinder with plastic sheeting.
Severe damage is caused by the brake fluid eating through the paint. Unprotected it
will break down the paint exposing bare unprotected metal.
• Pump the brake lever to insure the front brake pads is seated against the rotor.
• Remove screws or the cap off the master cylinder reservoir, fill reservoir. If equipped
with sight glass fill to indicator mark in window.
MOTORCYCLE FRONT BRAKE BLEEDING PROCEDURE
1. Place the wrench on the brake bleeding fitting of the front wheel. Select and press the
adapter over the top of the fitting.
2. Pump the handle several times, open fitting slightly watching for clean brake fluid and
fewer bubbles. It only takes about a 1/4 turn for fluid to flow into the jar.
3. Be cautious not to over fill the vacuum pump reservoir jar. Avoid brake fluid reaching
the vacuum pump, the fluid will damage the seals.
4. After expelling about 3 oz. into the jar, close the fitting.
WARNING: NEVER remove the jar lid before releasing the vacuum in the vacuum pump.

5. Empty the jar, check for any dirt or debris before replacing the lid on the jar. Be
cautious, master cylinders on motorcycles don’t hold much, add fluid if needed.
6. Reopen fitting and continue until all air is extracted.
7. When complete, continuing to draw vacuum, tighten bleeder fitting.
8. Top off front reservoir and reinstall cover. Pump lever several times, pedal should have
a positive, solid feel. If not, inspect line to ensure all fittings are tight. If brake still feels
slack, repeat bleeding process.
9. If there is still an issue contact a professional technician for the make and model of the bike.
10 .When equipped with dual disc front brakes, repeat bleeding process as though
there are two separate systems following steps from above.
MOTORCYCLE BLEEDING PREPARATION - REAR
Bleeding air from the rear brake system follows the same procedure as the front. The rear
reservoir is usually located under a side cover, with a hose leading to the rear master
cylinder.
• The brake caliper piston must not be seized. The pistons must be free to move within
the calipers.
• The master cylinder piston must not be seized. Piston must return to end of its stroke
when released.
• Inspect brake lines for cracks or wear, and that all fittings are tight.
• Cover any painted surface near the brake master cylinder with plastic sheeting.
• Pump the rear brake pedal to insure the rear brake pads is seated against the rotor.
• Remove the cap from the rear master cylinder reservoir, fill reservoir if needed. Pay
attention to the full indicator mark on the outside of the reservoir, do not over fill.
MOTORCYCLE REAR BRAKE BLEEDING PROCEDURE
1. Place the wrench on the brake bleeding fitting on the rear wheel. Select and press the
adapter over the top of the fitting.
2. Pump the rear brake pedal several times, open fitting slightly watching for clean brake
fluid and fewer bubbles. It only takes about a 1/4 turn for fluid to flow into the jar.
3. Be cautious not to over fill the vacuum pump reservoir jar. Again, avoid fluid reaching
the vacuum pump.
4. Extract about 3 oz. into the jar, close the fitting.
WARNING: NEVER remove the jar lid before releasing the vacuum in the vacuum pump.
5. Empty the jar, check for dirt, and replace the lid. Remember, motorcycles master
cylinders don’t hold much, add fluid if needed.
6. Reopen fitting and continue until all air is extracted.
7. When caliper is complete, continuing to draw vacuum, tighten bleeder fitting.
8. Top off front reservoir and reinstall cover. Pump brake pedal several times, pedal
should have a positive, solid feel. If not, inspect line to ensure all fittings are tight. If
brake still feels slack, repeat bleeding process.
9. If there is still an issue contact a professional technician for the make and model of
the bike.

• When you depress the brake pedal hydraulic force is transferred to the brake
calipers. Air is much less dense when compared to the brake fluid. This means if air
is in the lines it will compress too easily. When this happens, your brakes will feel too
soft or even spongy. Bleed system
• If brakes continue to be unresponsive and soft, you may have water in the system.
Water has a much lower boiling point than brake fluid. With excessive use brakes get
hot. If the liquid in the systems reaches a boiling point, you could lose your brakes.
The pedal and brake lever might be unresponsive and not pump up, causing the
vehicle not to stop. Have your brake fluid tested, if contaminated have the
system serviced by a professional mechanic.
• Brake squeaks slightly after bleeding, when applied. Clean the rotors and add Disc
Brake Quiet aerosol spray to the back of the pads.
• Original equipment rubber brake hoses have a tendency to expand, which also
causes spongy brakes. With time they lose the ability to flex and bend, replace with
braided steel lines. They don’t expand and offer a firmer, more consistent braking
experience.
