Rear Brake Rotor Replacement
Rear Brake Rotor Replacement
Tools Required
* J 2619-01 Slide Hammer
* J 42450-A Wheel Hub Resurfacing Kit
* J 21177-A Drum to Brake Shoe Clearance Gage
* J-46277 Rotor Removal Tool
Removal Procedure
Caution: Refer to Brake Dust Caution (Brake Dust Caution).
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 an appropriate tool, remove the brake fluid to the midway point before proceeding.
4. Raise the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair).
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (Service and Repair).
6. Compress the rear brake caliper pistons.
1. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard brake pad.
2. Slowly tighten the C-clamp until the pistons push into the brake caliper enough to slide the brake caliper off the rotor.
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.
9. If the brake rotor is stuck, perform the following:
1. Assemble J-46277 to J 2619-01.
2. Insert J-46277 between the rotor friction surfaces in the vent section of the rotor. DO NOT place the J-46277 on the rotor friction surface.
3. Using the J-46277 and J 2619-01, release the rotor from the hub assembly.
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 the relationship of the brake rotor and a wheel stud. In doing so, it will reduce the possibility of vibration in the brake system.
10. Remove the brake rotor.
11. Using the J 42450-A, clean the brake rotor to the rear axle flange contact area.
12. Refinish the rotor, if necessary. Refer to Brake Rotor Refinishing (Procedures).
13. Inspect the park brake components. If any of the following conditions are found, replace the affected parts.
* Bent or broken hold down spring
* Broken, cracked, or worn brake shoe lining
* Bent or damaged brake shoe
* Worn, bent, or damaged backing plate
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. Refer to Park Brake Adjustment (Adjustments).
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. Refer to Rear Brake Caliper Bracket Replacement (Rear Brake Caliper Bracket Replacement).
7. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (Service and Repair).
8. Lower the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair).
9. Refill the brake master cylinder reservoir, if needed. Refer to Master Cylinder Reservoir Filling (Master Cylinder Reservoir Filling).
Caution: Refer to Firm Brake Pedal Caution.
10. Pump the brake pedal slowly and firmly in order to seat the brake pads.
11. Burnish replaced or refinished rotors. Refer to Brake Pad and Rotor Burnishing (Brake Pad and Rotor Burnishing).
