DISC ROTOR INSPECTION

Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. Replace applicable part as necessary.

Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub 2 or more positions.





2. Using a dial indicator, check runout.

CAUTION: Make sure that wheel bearing axial end play is within the specifications before measuring runout. Refer to FAX-5, "FRONT WHEEL BEARING INSPECTION". Suspension

3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by one hole.

Thickness Inspection





1. Using a micrometer, check thickness of disc rotor. If thickness is outside the standard, replace disc rotor.
2. If runout is still out of the specification, grind rotor with on-car brake lathe ("MAD, DL-8700", "AMMCO 700 and 705" or equivalent) until runout becomes within the specified limit.
