Disc Rotor RUNOUT Check
- Check the rear hub unit bearing for free play and runout before the inspection of disc rotor runout limit. Ref. to DRIVE SHAFT SYSTEM>REAR HUB UNIT BEARING>INSPECTION .
- Check the disc rotor runout.
- Remove the caliper body assembly. Ref. to BRAKE>REAR DISC BRAKE ASSEMBLY>REMOVAL .
- Secure the disc rotor by tightening the five wheel nuts.
- Set a dial gauge 10 mm (0.39 in) inward from the disc rotor outer circumference, and check the outer disc rotor runout while rotating the disc rotor.
Preparation tool:
Dial gauge
Magnet stand
Disc rotor runout limit:
0.05 mm (0.002 in)
NOTE: < Example of magnet stand and dial gauge installation>
The location where the magnet stand is installed varies to stabilize the magnet stand. - Set a dial gauge 10 mm (0.39 in) inward from the disc rotor outer circumference, and check the inner disc rotor runout while rotating the disc rotor.
Preparation tool:
Dial gauge
Magnet stand
Disc rotor runout limit:
0.05 mm (0.002 in)
NOTE: < Example of magnet stand and dial gauge installation>
The location where the magnet stand is installed varies to stabilize the magnet stand. - If the disc rotor runout exceeds service limit, grind the disc rotor.
- Check the disc rotor thickness after grinding. Ref. to BRAKE>REAR DISC ROTOR>INSPECTION>DISC ROTOR THICKNESS CHECK .
