Removal Procedure
Warning: Refer to Brake Dust Warning Brake Dust Warning.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.
3. Remove the brake caliper bracket bolts (1).
Caution:
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.
4. Remove the brake caliper and bracket assembly and support with heavy mechanics wire.
5. Remove the brake rotor bolt (1).
6. Remove the brake rotor (1).
Installation Procedure
Note: 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.
1. Using the CH-42450-A - Wheel Hub Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
2. Using the CH-41013 - Rotor Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the rotor to the hub/axle flange.
3. Prepare the brake caliper bracket bolts and the bracket threaded holes for assembly:
* Thoroughly clean the residue from the bolt threads with denatured alcohol or equivalent and allow to dry.
* Thoroughly clean the residue from the threaded holes with denatured alcohol or equivalent and allow to dry.
* Apply threadlocker to 2/3 of the threaded length of the caliper bracket bolts. Refer to Adhesives, Fluids, Lubricants, and Sealers Fluid Type Specifications ,
* Ensure there are no gaps in the threadlocker along the length of the filled area of the bolts.
* Allow the threadlocker to cure approximately 10 minutes before installation.
4. Install the brake rotor (1).
Caution: Refer to Fastener Caution Fastener Caution.
5. Install the brake rotor bolt (1) and tighten to 14 Nm (124 lb in).
6. Position the brake caliper and bracket assembly to the steering knuckle.
7. Install the brake caliper bracket bolts (1) and tighten to 175 Nm (129 lb ft).
8. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.
9. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing Procedures.
