Removal Procedure
1. 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 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.
3. Remove the anti-rattle clips from the brake caliper bracket.
