Caution: Refer to Brake Dust Caution in Service Precautions.

Removal Procedure
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Remove the tire and wheel assembly.

3. Notice:
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.

Remove the brake caliper from the brake caliper mounting bracket and support the brake caliper with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake hose from the brake caliper.
