Inspection and Adjustment: Inspection

Appearance 

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace it if necessary. Refer to Removal and Installation (2WD), Removal and Installation (AWD).

Runout 

1. Fix 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 Inspection (2WD), Inspection (AWD).
3. Inspect the runout with a dial indicator to measure at 10 mm (0.39 in) inside the disc edge.

   Runout

   : Refer to Front 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, use the Pro-Cut PEM On-Car brake Lathe (Tool No. 38-PFM90.5) or equivalent.]
   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 Removal and Installation (2WD), Removal and Installation (AWD).

   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. Refer to Removal and Installation (2WD), Removal and Installation (AWD).
