Removal Procedure
Caution: Refer to Brake Dust Caution in the Preface section.
- Inspect the fluid level in the brake master cylinder reservoir.
- If the brake fluid level is midway between the maximum full point and
the minimum allowable level, then no brake fluid needs to be removed from reservoir
before proceeding.
If the brake fluid level is higher than midway between the maximum full point
and the minimum allowable level, then remove brake fluid to the midway point
before proceeding.
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Hand tighten two wheel lug nuts to retain the rotor to the hub.
Important: It is not necessary to disconnect the brake hose from the caliper when replacing
brake pads.
- Remove the rear caliper. Refer to
Rear Brake Caliper Replacement
.
- Remove the brake pads from the caliper bracket.
- Remove the retainer slides from the caliper bracket.
- Inspect
the following parts for cuts, tears, or deterioration. Replace any damaged parts:
- Inspect the caliper bolts (1, 3) for corrosion or damage. If corrosion
exists, use new components, including bushings, when installing the caliper. Do
not attempt to polish away the corrosion.
Installation Procedure
- Bottom the piston into the caliper bore. Use an old brake pad or wooden block
across the face of the piston. Use a C-clamp (3) over the caliper housing.
Tighten the clamp slowly to drive the piston into the caliper bore. Do not damage
the piston or the caliper boot.
- Install the 2 retainer slides to the caliper bracket.
- Install the rear pads to the caliper bracket.
- Lubricate the bolts and the bracket boots with GM P/N 18010908
silicone grease or equivalent.
- Install the caliper. Refer to
Rear Brake Caliper Replacement
.
- Remove the 2 hand tightened wheel lug nuts retaining the rotor to the
hub.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
- With the engine OFF, gradually apply the brake pedal to approximately
2/3 of its travel distance.
- Slowly release the brake pedal.
- Wait 15 seconds, then repeat steps 9 and 10 until a firm
brake pedal is obtained. This will properly seat the brake caliper pistons and
brake pads.
- Fill the master cylinder reservoir to the proper level. Refer to
Master Cylinder Reservoir Filling
in Hydraulic Brakes.
- Burnish the pads and rotors. Refer to
Brake Pad and Rotor Burnishing
.
