Inspection and Adjustment: Inspection

Appearance 

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace it if necessary. Refer to Rear Disc Brake .

Runout 

1. Secure the disc rotor to the wheel hub and bearing assembly with wheel nuts (2 points at least).
2. Check the wheel bearing axial end play before the inspection. Refer to NVH Troubleshooting Chart .
3. Inspect the runout with a dial indicator to measure at 20 mm (0.79 in) inside the disc edge.

   Runout (with it attached to the vehicle)

   : Refer to Rear Disc Brake .

4. 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.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. When refinishing, using Tool.

   Tool number

   : 38-PFM92 (--)

   CAUTION:

   • Check in advance that the thickness of the disc 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 rotor. Refer to General Specification .

   Wear thickness

   : Refer to Rear Disc Brake .

Thickness 

Check the thickness of the disc rotor using a micrometer. Replace the disc rotor if the wear thickness is below the limit. Refer to Removal and Installation of Brake Caliper Assembly and Rotor .
