Brake Caliper Bracket Replacement - Front

Caution: Refer to Brake Dust Caution in Cautions and Notices.

Removal Procedure

Note: 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.
3. Remove the anti-rattle clips from the brake caliper bracket.






4. Remove the brake caliper bracket mounting bolts (2).
5. Remove the brake caliper bracket (1).
6. Remove any contaminants or foreign material from the inside ends of the brake caliper bracket.
7. Clean the mounting surface and threads of the brake caliper bracket.
