#### INSPECTION

##### Front

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.

Fig. 1: Check the rotor for scoring

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 magnet type stand (attached to the shock absorber shaft) to determine runout. Position the dial so the stylus is 0.39 inch (10mm) from the outer edge of the rotor disc. The maximum allowable runout is 0.0028 inch (0.07mm). If runout exceeds the specification, replace the disc.

NOTE: 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.
