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.

Using the CH-42450-A Wheel Hub Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
Using the CH-41013 Rotor Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor.

NOTE:

Install new brake caliper bolts any time the bolts are removed.

Install 2 new brake caliper bolts (1) and tighten to 40 N.m (30 lb ft) + 90 degrees.
Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
Slowly release the brake pedal.
Wait 15 seconds, then repeat steps 8-9 until a firm brake pedal is obtained. This will properly seat the brake caliper piston and brake pads.
If the brake rotor was refinished or replaced, or if new brake pads were installed, burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing .
