Removal Procedure
Caution: Refer to Brake Dust Caution in Service Precautions.
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.
1. Remove the caliper from the mounting bracket and support the caliper with heavy mechanic's wire or equivalent. DO NOT disconnect the
hydraulic brake flexible hose from the caliper. Refer to Brake Caliper Replacement - Front.
2. Remove the brake pads.
