Brake Rotor Replacement - Rear

Removal Procedure
Tools Required
J 42450-A Wheel Hub Resurfacing Kit
J 21177-A Drum to Brake Shoe Clearance Gage

Caution: Refer to Brake Dust Caution In Service Precautions.

1. Inspect the brake fluid level in the brake master cylinder reservoir.





2. If the brake fluid is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.





3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, using a appropriate tool, remove the brake fluid to the midway point before proceeding.
4. Raise the vehicle.
5. Remove the tire and wheel assembly.





6. Compress the front brake caliper piston.
6.1. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard brake pad.
6.2. Slowly tighten the C-clamp until the piston pushes into the brake caliper enough to slide the brake caliper off the rotor.
6.3. Remove the C-clamp from the brake caliper.





7. Remove the rear brake caliper mounting bracket.





8. Remove the brake rotor retaining clips, if equipped.

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.

Important: If the brake rotor is not going to be replaced but just removed from the front hub to be refinished, mark the brake rotor left or right and relationship of the brake rotor and a wheel stud. In doing so, is will reduce the possibility of vibration in the brake system.





9. Remove the brake rotor.





10. Using the J 42450-A, clean the brake rotor to rear axle flange contact area.
11. Refinish the rotor if necessary.

Installation Procedure
1. Clean the park brake shoes using denatured alcohol.
2. Dry the park shoes using non-lubricated, filtered air.
3. Lubricate the contact area between the park brake shoe and the backing plate with high temperature silicone brake lubricant.

Important: It maybe necessary to readjust the park brake shoes to allow the brake rotor to be reinstalled.





4. Adjust the park brake shoe (1).

Important: Ensure that the rotor to axle flange relationships marks are aligned, if the brake rotor has been refinished, after the brake rotor is installed.





5. Install the brake rotor by slowly turning the rotor while pushing the rotor on the axle flange.
6. Install the rear brake caliper mounting bracket.
7. Install the tire and wheel assembly.
8. Lower the vehicle.
9. Refill the brake master cylinder reservoir, if needed.

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.

10. Pump the brake pedal slowly and firmly in order to seat the brake pads.





11. Burnish replaced or refinished rotors.
