For 1990-2009 cars

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: Bleed the ENTIRE brake system if air has entered the hydraulic brake system through either of the following conditions:

• | The master cylinder brake fluid level is at the bottom of the master cylinder reservoir.

• | Any part of the hydraulic brake system is opened between the master cylinder and any of the brake caliper flexible hoses.

### Brake System Bleeding with a Scan Tool (Preferred Method)

#### Tools Required

Scan Tool

Important: The Motor Rehome function cannot be performed if current DTCs are present. If DTCs are present, repair the vehicle and clear the DTCs before performing the Motor Rehome function.

1. Use a scan tool to perform the Motor Rehome function.
2. Bleed the hydraulic brake system. Refer to Brake System Pressure Bleeding or Brake System Manual Bleeding.

### Brake System Bleeding without a Scan Tool

Notice: This method can only be used if the amber ABS warning indicator is not illuminated and no DTCs are present.

1. Remove your foot from the brake pedal.
2. Start the engine and allow the engine to run for at least 10 seconds.
3. Observe the ABS warning indicator.

• | If the ABS indicator is ON, diagnose the antilock brake system malfunction. Refer to Diagnostic System Check in Antilock Brakes.

• | If the ABS indicator turns ON for approximately 3 seconds, then turns OFF and stays OFF, turn the ignition OFF and go to Step 4.

4. Remove your foot from the brake pedal.
5. Start the engine and allow the engine to run for at least 10 seconds.
6. Observe the ABS warning indicator.

• | If the ABS indicator turns ON and stays ON, diagnose the antilock brake system malfunction. Refer to Diagnostic System Check in Antilock Brakes.

• | If the ABS indicator turns ON for approximately 3 seconds, then turns OFF and stays OFF, turn the ignition OFF and bleed the entire brake system. Refer to Brake System Pressure Bleeding or Brake System Manual Bleeding.

### Brake System Pressure Bleeding Procedure

#### Tools Required

• | J 29532 Diaphragm Pressure Bleeder

• | J 35589 Bleeder Adapter

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.

1. Inspect and fill the master cylinder reservoir to the proper level as necessary. Refer to Master Cylinder Reservoir Filling
2. Assemble the components as shown.
3. Install the J 35589 to the master cylinder reservoir.
4. Connect the J 29532 to the J 35589 .
5. Adjust the J 29532 to 35-70 kPa (5-10 psi).
6. 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.
7. Adjust the J 29532 to 205-240 kPa (30-35 psi).

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 Manual Bleeding Procedure

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.
