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.
- Remove the brake caliper from the mounting bracket and support the brake caliper with heavy mechanic's wire, or equivalent. Discard the old caliper pin bolts, NEW bolts are supplied in the hardware kit. It is not necessary to disconnect the hydraulic brake flexible hose from the caliper. See FRONT BRAKE CALIPER .
