Caution: Refer to Brake Dust Caution in the Preface section.

Caution: Refer to Brake Fluid Irritant Caution in the Preface section.

Removal Procedure

  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 and support the vehicle. Refer to 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. Object Number: 370154  Size: SH
  7. Compress the brake caliper pistons.
  8. • Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad.
    • Slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores.
    • Remove the C-clamp from the caliper.
  9. Clean all dirt and foreign material from the brake hose end.

  10. Object Number: 367082  Size: SH

    Important: Install a rubber cap or plug to the exposed brake pipe fitting end to prevent brake fluid loss and contamination.

  11. Remove the brake hose to caliper bolt from the brake caliper.
  12. Remove and discard the 2 copper brake hose gaskets. These gaskets may be stuck to the brake caliper housing or the brake hose end.
  13. Remove the brake hose from the caliper.

  14. Object Number: 789166  Size: SH
  15. Remove the 2 brake caliper mounting bolts.
  16. Caution: Do not depress the brake pedal with the brake rotors/calipers and/or the brake drums removed. Damage to the brake system may result. If brake system damage occurs and is not repaired, vehicle damage and/or personal injury or death may result.

  17. Remove the brake caliper from the brake caliper mounting bracket.

Installation Procedure


    Object Number: 789166  Size: SH

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  1. Install the brake caliper to the brake caliper mounting bracket.
  2. Install the 2 brake caliper mounting bolts.
  3. Tighten
    Tighten the 2 brake caliper mounting bolts to 108 N·m (80 lb ft).

  4. Remove the rubber cap or plug from the exposed brake hose fitting end.
  5. Important: Install 2 New copper brake hose gaskets.

  6. Assemble the 2 New copper brake hose gaskets and the brake hose to caliper bolt to the brake hose.

  7. Object Number: 367082  Size: SH
  8. Install the brake hose to caliper bolt to the brake caliper.
  9. Tighten
    Tighten the brake hose to caliper bolt to 40 N·m (30 lb ft).

  10. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding in Hydraulic Brakes.
  11. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  12. Lower the vehicle.
  13. Fill the master cylinder reservoir to the proper level with clean brake fluid. Refer to Master Cylinder Reservoir Filling in Hydraulic Brakes.
