Warning: Refer to Brake Dust Warning in the Preface section.
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.
Preliminary Procedure
- Remove the tire and wheel. Refer to
Lifting and Jacking the Vehicle.
- Remove the brake caliper and support with heavy mechanics wire or equivalent. DO NOT disconnect the brake flexible hose from the caliper. Refer to
Front Brake Caliper Replacement.
- Remove the brake pads. Refer to
