Removal Procedure

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

  3. Object Number: 142244  Size: SH

    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.

    Important: Do NOT disconnect the hydraulic brake flexible hose from the caliper.

  4. Remove the brake caliper with brake pads as an assembly (2) from the steering knuckle and support the assembly with heavy mechanic's wire (1), or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose. Refer to Brake Caliper Replacement .
  5. Matchmark the position of the brake rotor to the wheel studs.
  6. Remove the brake rotor (3).
  7. Important: When a brake rotor has been separated from a hub/axle flange, the mating surface of the brake rotor must be cleaned of any rust or contaminants. Failure to do this may result in lateral runout of the brake rotor, and brake pulsation.

  8. If the brake rotor is to be reinstalled to the vehicle, use theJ 41013 in order to clean any rust or corrosion from the hub/axle flange mating surface of the brake rotor.
  9. Use the J 42450-A in order to clean the wheel hub flange.

Installation Procedure


    Object Number: 142244  Size: SH
  1. Install the brake rotor (3) to the hub axle flange. Use the matchmark made prior to removal for proper orientation to the flange.
