    CAUTION: Support the brake caliper with heavy mechanic 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 brake caliper from the brake caliper mounting bracket and support the brake caliper with heavy mechanic's wire (2), or equivalent. Do NOT disconnect the hydraulic brake flexible hose from the caliper. Refer to Front Brake Caliper Replacement (With RPO LNF)  or Front Brake Caliper Replacement (Without RPO LNF) .

    • Bent mounting tabs

    • Restricted caliper guide pin movement
    • Looseness in the brake caliper mounting bracket
    • Seized or binding caliper guide pins
    • Split or torn boots
