Removal Procedure

Tools Required

J 26900-1 Outside Micrometer

  1. Siphon two-thirds of the fluid from the master cylinder reservoir.
  2. Raise the vehicle. Support the vehicle. Refer the Vehicle Lifting and Jacking in General Information.
  3. Remove the tire and wheel assembly. Refer to Wheel Removal in Tires and Wheels.

  4. Object Number: 178629  Size: SH
  5. Remove the two caliper carrier bolts.

  6. Object Number: 178630  Size: SH
  7. Lift the caliper carrier, along with the caliper (2) and pads (3). Suspend the caliper with a wire (1) in order to prevent damage to the brake hose.

  8. Object Number: 196403  Size: SH
  9. Use a J 26900-1 in order to measure the rotor thickness. If the rotor thickness is less than 15 mm (0.59 in), replace the rotor.
  10. Remove two rotor screws.
  11. Remove the rotor from the wheel hub. If the rotor cannot be removed by hand, install two 8 mm bolts into the rotor. Tightening the bolts will force the rotor off the wheel hub.

Installation Procedure


    Object Number: 196403  Size: SH
  1. Install the rotor to the wheel hub. Secure with two screws.
  2. 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.

  3. Install the caliper carrier, with the caliper and pads, into position. Secure with two caliper carrier bolts.
  4. Tighten
    Tighten the caliper carrier bolts to 40-60 N·m (29-43 lb ft).

  5. Install the tire and wheel assembly. Refer to Wheel Installation in Tires and Wheels.
  6. Lower the vehicle.
