DISC ROTOR INSPECTION

Visual Inspection
Check surface of the disc rotor for uneven wear, cracks, and serious damage. If any non-standard condition is detected, replace applicable part.

Runout Inspection
1. Using wheel nuts, fix disc rotor to the wheel hub in 2 or more positions.





2. Inspect runout using a dial gauge.
Measurement position : At a point 10 mm (0.39 inch) from outer edge of the disc

Runout limit (with it attached to the vehicle) :0.07 mm (0.0028 inch) or less

CAUTION: Before measuring, make sure the axle endplay is °0 mm (0 inch). Refer to "FRONT WHEEL BEARING".

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

Thickness Inspection





Using a micrometer, check thickness of the disc rotor. If thickness does not meet specification, replace disc rotor.

Standard thickness : 28 mm (1.10 inch)

Minimum thickness : 26 mm (1.02 inch)

Maximum uneven wear (measured at 8 positions) : 0.015 mm (0.0006 inch) or less
