Caution: Do not move the vehicle until a firm brake pedal is obtained. Air in
the brake system can cause loss of brakes with possible personal injury.
Caution: Use only SUPREME 11 or equivalent DOT 3 brake fluid from a clean, sealed
container. Do not use fluid from an open container that may be contaminated
with water. Improper or contaminated fluid will result in damage to components
or loss of braking, with possible personal injury.
Caution: Do not overfill the brake fluid reservoir. Overfilling the brake fluid
reservoir may cause the brake fluid to overflow onto the engine exhaust components
during brake system service. The brake fluid is flammable and
may cause a fire and personal injury if the brake fluid contacts the engine
exhaust system components.
Notice: If any brake component is repaired or replaced such that air is allowed
to enter the brake system, the entire bleeding procedure must be followed.
Notice: Avoid spilling brake fluid on any of the vehicle's painted surfaces,
wiring, cables, or electric connectors. Brake fluid will damage the paint
and the electrical connections. If any fluid is spilled on the vehicle, flush
the area to lessen the damage.
Notice: Prior to bleeding the brakes, the front and rear displacement cylinder
pistons must be returned to the topmost position. The preferred method uses
a Scan Tool to perform the rehoming procedure. If a Scan Tool
is not available, the second procedure may be used, but it is extremely important
that the procedure be followed exactly as outlined.
Important: A Pressure Bleeding operation is necessary in order to remove air properly
whenever the Brake Pressure Modulator Valve has been removed or replaced.
Important: A bleeding operation is necessary in order to remove air when air is
introduced into the hydraulic brake system.
Bleed the hydraulic system at all four brakes if air has been introduced
through a low fluid level or by disconnecting brake pipes at the master cylinder.
If a brake hose or brake pipe is disconnected at one wheel, bleed
only that one wheel caliper. If brake pipes or hoses are disconnected
at any fitting located between the master cylinder and the brakes,
then only bleed the brake system served by the disconnected pipe
or hose.
With Scan Tool (Preferred Method)
Refer to
Antilock Brake System Automated Bleed Procedure
In Antilock brake system.
Without Scan Tool
Notice: This method can only be used if the amber ABS warning indicator is not
illuminated and no DTCs are present.
Important: Do not place your foot on the brake pedal through this entire procedure
unless specifically directed to do so.
- Remove foot from the brake pedal.
- Start the engine. Allow the engine to run for at least ten seconds
while observing the amber ABS warning indicator.
- If the amber ABS warning indicator turns on and stays on after
ten seconds, stop the bleeding procedure. Use a Scan Tool in order to diagnose
the ABS malfunction.
- If the amber ABS warning indicator turns on for approximately
three seconds, then turns off and stays off, turn the ignition off.
- Repeat the previous four steps one more time.
- Bleed the entire brake system.
Brake System Pressure Bleeding Procedure
Tools Required
• | J 29532 Diaphragm
Type Brake Bleeder |
Notice: Pressure bleeding equipment must be of the diaphragm type. It must have
a rubber diaphragm between the air supply and the brake fluid to prevent air,
moisture, and other contaminants from entering the hydraulic system.
Notice: Avoid spilling brake fluid on any of the vehicle's painted surfaces,
wiring, cables, or electric connectors. Brake fluid will damage the paint
and the electrical connections. If any fluid is spilled on the vehicle, flush
the area to lessen the damage.
- Inspect and fill the master cylinder reservoir to the proper level
as necessary. Refer to
Master Cylinder Reservoir Filling
.
- Assemble the components
as shown.
- Install the J 35589
to the master cylinder reservoir.
- Connect the J 29532
to theJ 35589
.
- Adjust theJ 29532
to 35-70 kPa (5-10 psi).
- Wait approximately 30 seconds, then inspect the entire
hydraulic brake system in order to ensure that there are no existing brake
fluid leaks. Repair any brake fluid leaks.
- Adjust theJ 29532
to 205-240 kPa (30-35 psi).
Important: Use a shop cloth in order to catch escaping brake fluid.
- Slowly open the ABS modulator brake pipe fitting (1) starting from
the first pipe on the left side in order to allow the brake fluid to flow.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.

Brake System Pressure Bleeding procedure. Proceed to Step 1.
Caution: Do not move the vehicle until a firm brake pedal is obtained. Failure
to obtain a firm pedal before moving vehicle may result in personal
injury.
- Road test the vehicle. Make several normal (non-ABS) stops from a moderate
speed in order to ensure proper brake system function. Allow adequate brake
system cooling time between stops.
Brake System Manual Bleeding Procedure
Important: This procedure may require the help of an assistant to apply the brake
pedal while the bleeder valves are opened and closed.
Important: Ensure that the master cylinder brake fluid level does not drop to the
bottom of the master cylinder reservoir. You will be instructed to Inspect
and fill the master cylinder reservoir at times during this procedure.
However, the actual frequency of master cylinder reservoir filling
REQUIRED will depend on the amount of fluid that is released. If the
brake fluid level drops to the bottom of the master cylinder reservoir,
start the bleed procedure again at Step 1.
- Inspect and fill the master cylinder reservoir to the proper level
as necessary. Refer to
Master Cylinder Reservoir Filling

must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
