INSPECTION



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.
