Removal Procedure

    Warning: Refer to Brake Dust Warning in the Preface section.

  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, then no brake fluid needs to be removed from the 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.
  3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.

    4. 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.

  4. Using a C-clamp installed to the center of the outer brake pad and the back of the caliper, slowly compress the caliper piston into its bore just enough to remove the caliper from the mounting bracket.

    5. Do not exceed 1 mm (0.039 in) of caliper piston travel.

  5. Remove the 2 brake caliper guide pin bolts.

    6. 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 bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.

  6. Remove the brake caliper from the brake caliper mounting bracket.

    7. Object Number: 1335587 Size: SH
  7. Remove the brake pads (1) from the brake caliper mounting bracket (3).
