Special tool
 | Dial indicator stand 100-D002 (D78P-4201-B) |
Examination
1. Loosen the wheel nuts.
2. Raise and support the vehicle. Refer to Section 100-02 for additional information.
3. Remove the wheel.
4. Remove the brake pads. For additional information, refer to Section 206-03.
5. To hold the brake disc in place, turn the wheel nuts over and reinstall them.
6. Mount the dial indicator, mounted on the tripod, onto the suspension post.
7.
NOTE: If runout is out of specification, check wheel hub axial runout.
Using a suitable dial indicator, measure the runout of the inner and outer surfaces of the disc.
- 1. Position the indicator so that it contacts the disc 10 mm from the outer edge.
- 2. Rotate the dial slowly. The full reading of the dial indicator should not exceed the value specified in the specification. For more information, refer to the Specification chapter in this section.
8. Check the difference in brake disc thickness.
- Using a suitable micrometer, measure the disc thickness at eight locations, 45 degrees apart and 15 mm from the outer edge of the brake disc.
- If any of the readings varies by 0.015 mm or more or the brake disc thickness is less than the specified minimum, a new brake disc should be installed.
9. Remove the brake disc. For additional information, refer to Section 206-03.
10.
NOTE: Make sure the wheel hub surface is clean and free of rust or foreign material.
Using a special tool, check the axial runout of the wheel hub.
- Rotate the wheel hub slowly and check the runout. If the runout exceeds the specification. Install a new wheel hub and recheck. Refer to Section 204-01 for additional information.
11. If the hub axial runout is within specification, install a new brake rotor and recheck the brake rotor runout. Refer to Section 206-03 for additional information.
