CAUTION: Refer to Brake Dust Caution .
NOTE: 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.

Preliminary Procedures

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
  2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
