Removal Procedure

WARNING: This page is about a different car, the 2008 Chevrolet Malibu Classic. However, it is still accessible from the selected car via links, so may be relevant.
    CAUTION: Refer to Brake Dust Caution .
  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. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation .
  5. 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.

    NOTE: 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.
  7. To loosen the brake caliper pin bolts, hold the brake caliper guide pin with a wrench.
  8. Remove the lower brake caliper pin bolt.
  9. Pivot the brake caliper upward and support with mechanics wire as shown.
  10. Remove the brake pads (2) from the disc brake caliper bracket.
