Warning: Refer to Brake Fluid Irritant Warning in the Preface section.
Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution in the Preface
section.
Note: Before performing the ABS Automated Bleed Procedure, first perform a manual or pressure
bleed of the base brake system. Refer to Hydraulic Brake System Bleeding. The automated bleed
procedure is recommended when one of the following conditions exist:
• Base brake system bleeding does not achieve the desired pedal height or feel
• Extreme loss of brake fluid has occurred
• Air ingestion is suspected in the secondary circuits of the brake modulator assembly
The ABS Automated Bleed Procedure uses a scan tool to cycle the system solenoid valves and run
the pump in order to purge any air from the secondary circuits. These circuits are normally closed
off, and are only opened during system initialization at vehicle start up and during ABS operation.
The automated bleed procedure opens these secondary circuits and allows any air trapped in these
circuits to flow out toward the brake corners.
Performing the Automated Bleed Procedure
Caution: The Auto Bleed Procedure may be terminated at any time during the process by
pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed
procedure will be given. After exiting the bleed procedure, relieve bleed pressure and
disconnect bleed equipment per manufacturers instructions. Failure to properly relieve
pressure may result in spilled brake fluid causing damage to components and painted
surfaces.

11. Follow the scan tool directions until the desired brake pedal height is achieved.
12. If the bleed procedure is aborted, a malfunction exists. Perform the following steps before
resuming the bleed procedure:
• If a DTC is detected, refer to Diagnostic
the appropriate DTC.
• If the brake pedal feels spongy, perform the conventional brake bleed procedure again.
Refer to Hydraulic Brake System Bleeding.
13. When the desired pedal height is achieved, press the brake pedal to inspect for firmness.

Caution: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is
separated from its mount and the hydraulic flexible brake hose is still connected. Failure to
support the caliper in this manner will cause the flexible brake hose to
caliper, which may cause damage to the brake hose and in turn may cause a brake fluid
leak.

1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the brake fluid level is midway between the maximum-full point and the minimum
allowable level, no brake fluid needs to be removed from the reservoir before
proceeding.
3. If the brake fluid level is higher than midway between the maximum-full point and the
minimum allowable level, remove brake fluid to the midway point before proceeding.

1. Thoroughly clean the brake pad hardware mating surfaces of the caliper
bracket of any debris and corrosion.
2. Inspect the brake caliper guide pins for freedom of movement
condition of the guide pin boots. Move the guide pins inboard and outboard
within the bracket bores without disengaging the slides from the boots and
observe for the following:
• Restricted caliper guide pin movement
• Looseness in the brake caliper mounting bracket
• Seized or binding caliper guide pins
• Split or torn boots
3. If any of the conditions are found, the brake caliper guide pins and/or boots
require replacement.
4. Apply a very thin coating of high temperature silicone brake lubricant to the
pad hardware mating surfaces of the caliper bracket only.
5. If replacing the brake pads, DO NOT reuse the brake pad
brake pad springs.
6. After the installation is complete, with the engine OFF, gradually apply the
brake pedal to approximately 2/3 of its travel distance.
7. Slowly release the brake pedal.
8. Wait 15 seconds, then repeat steps 6-7 until a firm brake pedal is obtained.
This will properly seat the brake caliper piston and brake pads.
9. Fill the master cylinder reservoir to the proper level. Refer to Master
Reservoir Filling.
10. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing.
Warning: Refer to Brake Dust Warning in the Preface section.

Caution: When using a large C-clamp to compress a caliper piston into a caliper
bore of a caliper equipped with an integral park brake mechanism, do not exceed
more than 1 mm (0.039 in) of piston travel. Exceeding this amount of piston travel
will cause damage to the internal adjusting mechanism and/or the integral park
brake mechanism.

Tip
• Use a large C-clamp to compress the brake caliper piston slightly to ease
caliper removal. DO NOT exceed 1 mm (0.039 in) of caliper piston travel.
• Using a spanner type tool or equivalent, rotate the brake caliper piston
clockwise while applying slight inward pressure to retract the piston into the
caliper.
• Without disconnecting the brake hose position the brake caliper aside and
support with heavy mechanics wire or equivalent.

Disc Brake Pad - Outer
Procedure
6
1. Thoroughly clean the brake pad mating surfaces of the caliper bracket of any
debris and corrosion.
2. Inspect the brake caliper guide pins for freedom of movement and inspect the
condition of the guide pin bushings. Move the guide pins in and out within the
bushings and observe for the following:
• Restricted caliper guide pin movement
• Seized or binding caliper guide pins
• Split or torn bushings
3. If any of the conditions listed are found, the brake caliper guide pins and/or
bushings require replacement.
4. After the installation is complete, with the engine OFF, gradually apply the
brake pedal to approximately 2/3 of its travel distance.
5. Slowly release the brake pedal.
6. Wait 15 seconds, then repeat steps 4-5 until a firm brake pedal is obtained.
This will properly seat the brake caliper piston and brake pads.
7. Fill the master cylinder to the proper level. Refer to Master
Filling.
8. Burnish the pads and rotors. Refer to Brake Pad and Rotor Burnishing.
Warning: Road test a vehicle under safe conditions and while obeying all traffic laws. Do not
attempt any maneuvers that could jeopardize vehicle control. Failure to adhere to these
precautions could lead to serious personal injury and vehicle damage.
Burnishing the brake pads and brake rotors is necessary in order to ensure that the braking
surfaces are properly prepared after service has been performed on the disc brake system.
This procedure should be performed whenever the disc brake rotors have been refinished or
replaced, and/or whenever the disc brake pads have been replaced.
1. Select a smooth road with little or no traffic.
2. Accelerate the vehicle to 48 km/h (30 mph).
Note: Use care to avoid overheating the brakes while performing this step.
3. Using moderate to firm pressure, apply the brakes to bring the
the brakes to lock.
4. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient
cooling periods between stops in order to properly burnish the brake pads and rotors.
