DISC ROTOR INSPECTION

Visual Inspection
Check surface of 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, install disc rotor to wheel hub. (2 or more positions.)
2. Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in) inside disk edge.]
Runout limit (on vehicle): 0.05 mm (0.0020 in)

NOTE: Make sure that wheel bearing axial end play is within the specification before measuring runout.

3. If runout is outside the limit, find the minimum runout point by shifting mating positions of disc rotor and wheel hub by one hole.
4. If runout still out of specification, turn rotor with on-car brake lathe.

Thickness Inspection





Using a micrometer, check thickness of disc rotor. If thickness is either at or below the wear limit, or exceeds maximum uneven wear, replace disc rotor.
Standard thickness: 18.0 mm (0.709 in)
Wear limit: 16.0 mm (0.630 in)
Maximum uneven wear: 0.015 mm (0.0006 in) (measured at 8 positions)
