Thickness & Parallelism
Raise and support vehicle. Remove wheels. Remove brake pads. See FRONT DISC BRAKE PADS under REMOVAL & INSTALLATION. Using a micrometer, measure disc thickness at 8 points approx. 45° apart and 0.4" (10 mm) in from outer edge of disc. Replace brake disc if smallest measurement is less than the MAX. Refinishing limit. See DISC BRAKE SPECIFICATIONS .
NOTE:
This is the maximum allowable difference between the thickness measurements.
If the disc is beyond the service limit for parallelism, refinish brake disc with an on-car brake lathe. See DISC BRAKE SPECIFICATIONS . If it is beyond service limit for refinishing, replace. See BRAKE DISC (FRONT & REAR) under REMOVAL & INSTALLATION.
