Fig. Fig. 1 To remove the rotor, simply lift it off of the steering knuckle, after the caliper is removed
REMOVAL & INSTALLATION
Remove the caliper, as outlined earlier in this section. It is not necessary to disconnect the brake hose, just suspend it from the body of the car with a piece of wire.
Remove the rotor.
Installation is the reverse of the removal procedure.
Fig. Fig. 2 Check the rotor runout with a dial indicator
Check the rotor surface for wear or scoring. Deep scoring, grooves or rust pitting can be removed by refacing, a job to be referred to your local machine shop or garage. Minimum thickness is stamped on the rotor. If the rotor will be thinner than this after refinishing, it must be replaced.
Check the rotor parallelism; it must vary less than 0.0005 in. (0.013 mm) measured at four or more points around the circumference. Make all measurements at the same distance in from the edge of the rotor. Refinish the rotor if it fails to meet this specification.
Measure the disc runout with a dial indicator. If runout exceeds 0.005 in. (0.127 mm), and the wheel bearings are OK (if runout is being measured with the disc on the car), the rotor must be refaced or replaced as necessary.
