Tools Required
Caution: Refer to Brake Dust Caution in the Preface section.
Removal Procedure
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Install a C-clamp over the body of the brake caliper, with the C-clamp
ends against the rear of the caliper body and the outboard disc brake pad.
- Using the C-clamp, compress the piston into the caliper bore just enough
to allow the caliper to slide away from the rotor.
- Remove the C-clamp.
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.
- Remove the brake caliper and bracket from the vehicle, support
the caliper assembly away from the rotor. Refer to
Rear Brake Caliper Bracket Replacement
.
- Mark the relationship of the rotor to the hub.
- Remove the brake rotor.
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 (LOR) of the brake rotor, and brake pulsation.
- Use the J 42450-A
, thoroughly
clean any rust or corrosion from the mating surface of the hub/axle flange.
- Use theJ 41013
, thoroughly
clean any rust or corrosion from the mating surface and mounting surface of the brake
rotor.
- Inspect the mating surfaces of the hub/axle flange and the rotor to ensure
that there are no foreign particles or debris remaining.
- Install the brake rotor to the hub/axle flange. Use the matchmark made
prior to removal for proper orientation to the flange.
- If the brake rotor was removed and installed as part of a brake system
repair, measure the assembled lateral runout (LRO) of the brake rotor to ensure
optimum performance of the disc brakes. Refer to
Brake Rotor Assembled Lateral Runout Measurement
.
- If the brake rotor assembled LRO measurement exceeds the specification,
bring the LRO to within specifications. Refer to
Brake Rotor Assembled Lateral Runout Correction
.
- Install the brake caliper and bracket assembly. Refer to
Rear Brake Caliper Bracket Replacement
.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Lower the vehicle.
- If the brake rotor was refinished or replaced, or if new brake pads were
installed, burnish the pads and rotors. Refer to
Brake Pad and Rotor Burnishing
.
