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-41013 resurfacer, thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor (2).
- 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 mark made prior to removal to ensure proper orientation to the flange.
- Install the brake rotor screw and tighten to 9 N.m (80 lb in).CAUTION: Refer to Fastener Caution .
- If the brake rotor was removed and installed as part of a brake system repair, measure the assembled LRO of the brake rotor to ensure optimum performance of the disc brakes. Refer to Brake Rotor Assembled Lateral Runout Measurement .
- Remove the support and install the brake caliper and the brake caliper bracket as an assembly to the steering knuckle.
- Install NEW brake caliper bracket bolts (1) and tighten a first pass to 100 N.m (74 lb ft).
- Tighten the NEW brake caliper bracket bolts a final pass to an additional 20 - 30 degrees, using the EN-45059 meter.
- Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
- Lower the vehicle.
