REMOVAL & INSTALLATION
See Figure 1
- Siphon 2 / 3 of the brake fluid from the master cylinder reservoir.
- Loosen the wheel lug nuts, then raise and safely support the vehicle.
- Remove the wheel and tire assembly, then reinstall two wheel nuts to retain the rotor.
- Remove the caliper from the vehicle.
- Remove the rotor by pulling it straight off the wheel lug studs and hub assembly.
- To install, reposition the rotor and install the caliper and pads as outlined earlier.
- 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 (21.08 mm). If the rotor will be thinner than this after refinishing, it must be replaced.
- Check the rotor parallelism (thickness variation); it must vary less than 0.01mm 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 0.10mm, 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.
