J 42450-A Wheel Hub Cleaning Kit

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 brake hose from the caliper or separate the caliper from the caliper bracket.

1. Remove the rear brake caliper. Refer to Rear Brake Caliper Replacement .

Notice: Support the caliper with a piece of wire to prevent damage to the brake line.

2. Remove and suspend the caliper and caliper bracket assembly.



3. Remove and dispose of the sheet metal retainers.



4. Remove the rotor. Slowly turn the rotor while pulling the rotor away from the axle flange.
5. Inspect and clean all parts. Replace parts as necessary.
6. Refinish the rotor if required. Refer to Brake Rotor Refinishing .

Caution: Do not move the vehicle until a firm brake pedal is obtained. Failure to obtain a firm pedal before moving vehicle may result in personal injury.

Notice: Whenever the rotor has been separated from the axle flange, clean any rust or foreign material from the mating surface of the axle flange and brake rotor. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.

1. Use the J 42450-A to clean the axle flange.



2. Install the rotor. Slowly turn the rotor while pushing the rotor on the axle flange.
3. Verify that the brake pads are in place.
4. Install the caliper and caliper bracket assembly over the rotor.
5. Install the rear brake caliper. Refer to Rear Brake Caliper Replacement .
6. Burnish replaced or refinished rotors. Refer to Brake Pad and Rotor Burnishing .
