DISC ROTOR: Inspection
APPEARANCE
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if there are.
RUNOUT
1. Fix the disc rotor to the wheel hub and bearing assembly with wheel nuts (2 points at least).
2. Inspect the runout with a dial gauge. [Measured at 10 mm (0.39 in) inside disc edge.]
NOTE: Check the wheel bearing axial end play before the inspection. Refer to RAX-15, "Wheel Bearing". See: Steering and
Suspension/Suspension
3. Find the installation position that has a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation position by one
hole at a time if the runout exceeds the limit value.
4. Replace the disc rotor if the runout is outside the limit even after performing the above operation.
THICKNESS
Check the thickness of the disc rotor using a micrometer. Replace the disc rotor if the thickness is below the wear limit.
