REMOVAL & INSTALLATION
- Remove the brake pads and caliper, or caliper and support as previously described.
- Check the disc run-out with a dial indicator, if available. See the rotor inspection information for details.
- Remove the grease cap from the center of the hub. Remove the cotter pin, castellated nut and bearing.
- Remove the wheel hub with the disc rotor attached.
- Inspect the rotor. See the rotor inspection information for details.
- Check the wheel bearings, repack them with grease if necessary.
- Installation is the reverse of removal. Before installation, coat the hub oil seal with multi-purpose grease. Install the hub and disc rotor. Adjust the wheel bearing preload. See the wheel bearing information.
Examine the disc. If it is worn, warped or scored, it must be replaced. Check the thickness of the disc against the specifications given in the Disc and Pad Specifications chart. If it is below specifications, replace it. Use a micrometer to measure the thickness.
The disc run-out should be measured before the disc is removed and again, after the disc is installed. Use a dial indicator mounted on a stand to determine run-out. If run-out exceeds 0.15mm (all models), replace the disc.
Be sure that the wheel bearing nut is properly tightened. If it is not, an inaccurate run-out reading may be obtained. If different run-out readings are obtained with the same disc, between removal and installation, this is probably the cause.
