Removal Procedure

    Object Number: 369668 Size: SH
  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 removedfrom 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 and support the vehicle. Refer to in Lifting and Jacking the Vehicle in General Information.
  5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  6. Inspect the caliper operation. Refer to Brake Caliper Inspection .

    7. Notice: 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.

  7. Remove the caliper from the mounting bracket and support the caliper with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper. Refer to Front Brake Caliper Replacement .
  8. Remove the brake pads from the caliper mounting bracket.
  9. Remove and discard the anti-rattle clips from the brake caliper mounting bracket.
  10. Inspect the caliper and mounting bracket. Refer to Brake Caliper Inspection .

Installation Procedure

    Object Number: 369668 Size: SH

  2. Install the brake pads to the caliper mounting bracket.
  3. Install the brake caliper. Refer to Front Brake Caliper Replacement .
  4. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

  7. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
  8. Slowly release the brake pedal.
  9. Wait 15 seconds, then repeat steps 7-8 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
