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 suitably support the vehicle.
  5. Remove the tire and the wheel assembly.
  6. Compress the front caliper piston. See Fig 1 .
    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.
  7. Remove the brake hose, caliper bolt and the 2 copper brake hose gaskets from the caliper. See Fig 2 .
  8. Discard the 2 copper brake hose gaskets. These gaskets may be stuck to the brake caliper housing or the brake hose end.
  9. Plug the opening in the brake hose in order to prevent excessive brake fluid loss and contamination. Do not pinch off the brake hose with any tools.
  10. Remove the caliper lock mounting bolt. See Figure .
  11. Remove the support key and the spring using a brass punch and a hammer to drive out the support key. See Fig 3 .
  12. Remove the caliper assembly.
  13. Inspect the inside of the caliper assembly for signs of fluid leakage. See BRAKE CALIPER INSPECTION  under ADJUSTMENTS & INSPECTION.
  14. Use a wire brush to remove any corrosion from the machined surfaces of the anchor plate and the caliper.
  15. Remove the brake pads from the caliper.
