Removal Procedure
Caution: Refer to Brake Dust Caution in Service Precautions.
1. Remove the caliper from the mounting bracket and support the caliper with heavy mechanics wire or equivalent. It is not necessary to disconnect
the hydraulic brake flexible hose from the caliper.

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.

3. Remove the caliper bracket bolts (2).
4. Remove the caliper bracket (1).
