REMOVAL & INSTALLATION
- Raise the vehicle and support it with jackstands.
- Remove the front wheel, handbrake cable, guides, caliper and caliper support in the same manner as outlined in this section.
- Safety wire the caliper to a suspension member, so that it is out of the way.
- Unfasten the two bolts which hold the caliper bracket to the housing and remove the bracket from the housing.
- Remove the axle shaft nut and pull the disc off the axle shaft with a puller.
- Remove the 4 bolts which hold the disc to the hub.
- Reverse the above process to install the rotor.
- Tighten caliper bracket bolts to 36-51 ft. lbs. (48-69 Nm).
- Check the disc for any obvious defects such as excessive rust, chipping, or deep scoring. Light scoring is normal on disc brakes.
- Install a dial indicator on the caliper so that its feeler will contact the disc about 0.20 in. (5 mm) from the outer edge of the rotor.
- Turn the disc and observe the runout reading. If the reading exceeds 0.0039 in. (0.10 mm), the disc should be replaced.
All brake rotors (discs) have a minimum thickness dimension cast into them, on the hub between the lugs. This is the minimum wear dimension and not a refinish dimension. Do not reuse a brake rotor that will not meet specifications. Replace with a new rotor.
Refinishing of brake rotors can be handled at machine shops equipped for brake work.
