Removal (Front)

WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the fluid level in the brake master cylinder.
  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.
  4. Raise and support the vehicle.
  5. Remove the tire and wheel assembly.
  6. Compress the front caliper piston.
    1. Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad.
    2. Slowly tighten the C-clamp until the piston pushes into the caliper bore enough to slide the caliper off the rotor.
    3. Remove the C-clamp from the caliper.
    CAUTION: Support the brake caliper with heavy mechanic's 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 bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
  7. Remove the caliper from the mounting bracket and support the caliper with heavy mechanic's wire or equivalent. See Fig 1 . Do not disconnect the hydraulic brake flexible hose from the caliper. See BRAKE CALIPER  .
  8. Remove the inboard lining. See Fig 2 .
  9. Remove the outboard lining.
  10. Inspect the following parts for cuts, tears, or deterioration. Replace any damaged parts:
  11. Inspect the caliper assembly for signs of fluid leakage. If any leakage is detected, see BRAKE CALIPER  under OVERHAUL.
  12. Use a wire brush to remove any corrosion from the machined surfaces of the steering knuckle and the caliper.
