Component Name

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 Procedures

  1. Inspect the fluid level in the brake master cylinder reservoir.
  2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
  3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
  4. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
  5. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation.

Spring Clip (Qty: 2)

Procedure

  1. After the installation is complete and with the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
  2. Slowly release the brake pedal.
  3. Wait 15 seconds, then repeat Steps 1-2 until a firm brake pedal is obtained. This will properly seat the brake caliper piston and the brake pads.
  4. Fill the master cylinder. Refer to Master Cylinder Reservoir Filling.
  5. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing.
