Inspection and Adjustment: Inspection

Appearance 

Check surface of disc rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.

Runout 

1. Check the wheel bearing axial end play before the inspection. Refer to Inspection .
2. Secure the disc rotor to the wheel hub and bearing assembly with wheel nuts at two wheel nut locations.

3. Inspect the runout with a dial gauge, measured at 10 mm (0.39 in) inside the disc edge.

   Runout (with it attached to the vehicle)

   : Refer to Front Disc Brake .

4. Find the installation position with 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.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. When refinishing, use Tool.

   Tool number

   : 38-PFM92 (--)

   CAUTION:

   • Check in advance that the thickness of the disc brake rotor is wear thickness + 0.3 mm (0.012 in) or more.
   • If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc brake rotor. Refer to Removal and Installation .

   Wear thickness

   : Refer to Front Disc Brake .

Thickness 

Check the thickness of the disc rotor using a micrometer. Replace the disc rotor if the thickness is below the wear limit.
