Removal Procedure

    Object Number: 142234 Size: SH
  1. Remove 2/3 of the brake fluid from the master cylinder assembly.
  2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  3. Mark the relationship of the wheel to the hub in order to ensure proper wheel balance upon reassembly.
  4. Remove the tire and wheel assembly. Refer to Wheel Removal in Tires and Wheels.
  5. Reinstall 2 wheel nuts in order to retain the rotor to the hub.
  6. Push the piston into the caliper bore in order to provide clearance between the linings and the rotor.
    7. 6.1. Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad.
    6.2. Slowly tighten the C-clamp until the piston is pushed into the caliper bore far enough to slide the caliper assembly off the rotor.

    Object Number: 176035 Size: SH
  7. Remove the bolt (1) that attaches the inlet fitting only when the caliper is to be removed from the vehicle for overhaul or replacement. If only the brake pads are being replaced, do not disconnect the inlet fitting.
  8. Plug the caliper housing and the brake hose in order to prevent fluid loss and contamination.

    9. Object Number: 176014 Size: SH
  9. Remove the caliper mounting bolts (2).

  11. Remove the 2 guide pins (10) and the guide pin boots from the caliper bracket (2).
  12. Inspect the guide pins (10) and the bores for corrosion.
  13. Inspect the boots for cuts or nicks.

    14. Important: Do not attempt to polish away corrosion.

  14. If you find the following damage when you install the caliper, replace the damaged components with new parts:
    15. • The guide pin boots
    • The guide pins
    • The bores

Installation Procedure

    Object Number: 176011 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 (13).

    2. Tighten
    Tighten the caliper bolts to 31 N·m (23 lb ft).


    Object Number: 176035 Size: SH
  2. Install the brake hose (2) with the inlet fitting.

    3. Tighten
    Tighten the inlet fitting bolt to 50 N·m (37 lb ft).

  3. Remove the wheel nuts that secure the rotor to the hub.
  4. Install the wheel and tire assembly. Align the index marks that were made during removal. Refer to Wheel Installation in Tires and Wheels.
  5. Lower the vehicle.
  6. Fill the master cylinder to the proper level with clean brake fluid. Refer to Master Cylinder Reservoir Filling .
