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.

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.

Refer to Antilock Brake System Automated Bleed Procedure In Antilock brake system.

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.

1. Remove foot from the brake pedal.
2. Start the engine. Allow the engine to run for at least ten seconds while observing the amber ABS warning indicator.
3. 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.
4. If the amber ABS warning indicator turns on for approximately three seconds, then turns off and stays off, turn the ignition off.
5. Repeat the previous four steps one more time.
6. Bleed the entire brake system.

Tools Required

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.

1. Clean the brake fluid reservoir cover and the surrounding area.
2. Remove the brake fluid reservoir cover.
3. Inspect the brake fluid reservoir level. Refer to Master Cylinder Reservoir Filling . Add clean brake fluid as required.
4. Connect the J 35589 to the brake fluid reservoir.
5. Adjust the pressure bleed equipment to 35-70 kPa (5-10 psi).
6. Complete the following procedures using pressure bleeding equipment that is connected and pressurized:

6.1.	Attach a clear plastic bleeder hose to the rearward bleeder valve on the brake modulator.

6.2.	Submerge the opposite hose end in a clean container partially filled with clean brake fluid.

6.3.	Slowly open the bleeder valve. Allow the fluid to flow until no air is seen in the fluid.

6.4.	Close the valve when the fluid flows without any air bubbles.

Important: Use a shop cloth in order to catch escaping brake fluid. Prevent the fluid from running down the motor pack case or into the electrical connector. Also, do not allow brake fluid to contact any painted surfaces as surface damage will occur. If brake fluid does contact any surface, flush the surface with water to lessen the damage.

6.5.	Repeat the previous four steps until no air bubbles are present.

6.6.	Relocate the bleeder hose on the forward brake modulator bleeder valve.

6.7.	Submerge the opposite hose end in a clean container partially filled with clean brake fluid.

6.8.	Slowly open the bleeder valve. Allow the fluid to flow until no air is seen in the fluid.

6.9.	Close the valve when the fluid flows without any air bubbles.

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.

Important: Use a shop cloth to catch escaping brake fluid. Take care to prevent fluid from running down the motor pack base or into the electrical connector. also do not allow the brake fluid to contact any painted surfaces as surface damage will occur. If the brake fluid does contact any surface, flush the surface with water to lessen the damage.

21.1.

Using the Scan Tool, release then apply each motor 2-3 times and cycle each solenoid 5-10 times.

Important: Once the fluid is visibly flowing from both modulator bleeder valves, the ABS brake modulator/master cylinder assembly is sufficiently full of fluid. However, it may not be completely purged of air. At this point, move to the wheel brakes and bleed the brakes. This ensures that the lowest points in the system are completely free of air. Then purge the ABS brake modulator/master cylinder assembly of any remaining air.

5.6.	Repeat the previous three steps until air bubbles are no longer present.
