Removal & Installation
- Before servicing the vehicle, refer to the Precautions Section.
- Raise and safely support the vehicle.
- Remove the tire and wheel assembly.
Install a large C-clamp, over the body of the brake caliper with the C-clamp ends against the rear of the caliper body and against the outer brake pad.
WARNINGWhen using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake mechanism, do not exceed more than 0.039 inch (1mm) of piston travel. Exceeding this amount of piston travel will cause damage to the internal adjusting mechanism and/or the integral park brake mechanism.
- Tighten the C-clamp just enough to compress the caliper piston 0.039 inch (1mm) of travel only.
Remove the C-clamp from the caliper.
WARNINGSupport 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.
NOTEDo NOT disconnect the hydraulic brake flexible hose from the caliper.
- Remove the brake caliper and the caliper mounting bracket as an assembly from the steering knuckle and support the assembly with heavy mechanic's wire, or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose.
- Mark the position of the brake rotor to the wheel studs.
- Remove the brake rotor.
Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled Lateral Runout (LRO) of the brake rotor, which could lead to brake pulsation.
- Using J 42450-A, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
- Using J 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 marks 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.
- If the brake rotor assembled LRO measurement exceeds the specification, bring the LRO to within specifications.
- Remove the support, and install the brake caliper and the brake caliper bracket as an assembly to the steering knuckle. Refer to brake caliper, removal and installation.
- Install the tire and wheel assembly. Tighten lug nuts to 100 ft. lbs (140 Nm).
- Lower the vehicle.
- If the brake rotor was refinished or replaced, or if new brake pads were installed, burnish the pads and rotors.
