Removal Procedure

  1. Check to be sure that the park brake is released.
  2. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  3. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

  4. Object Number: 64001  Size: SH
  5. Disconnect the park brake cable from the park brake apply lever.
  6. 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 brake caliper and the caliper mounting bracket as an assembly from the suspension knuckle and support the assembly with heavy mechanic's wire, or equivalent; ensure that there is no tension on the hydraulic brake flexible hose. Do NOT disconnect the hydraulic brake flexible hose from the caliper. Refer to Rear Brake Caliper Bracket Replacement .
  8. Remove the brake rotor. Do not force the rotor off. If the rotor is difficult to remove, ease it off by gently rotating it as you pull outward.

  9. Object Number: 63987  Size: SH

Installation Procedure

    Important: Whenever the rotor has been separated from the wheel bearing flange, clean any rust or contaminants from the wheel bearing flange and the brake rotor mating surfaces. Failure to do this may result in increased lateral runout of the brake rotor, and brake pulsation.

  1. Use the J 42450-A in order to clean any rust or corrosion from the wheel hub surface.

  2. Object Number: 64001  Size: SH
  3. Connect the park brake cable to the park brake apply lever.
