INSPECTION
1. DISC ROTOR RUNOUT CHECK
1. Check the hub unit COMPL - rear axle for free play and runout before the inspection of disc rotor runout limit. Rear Hub Unit Bearing > INSPECTION">
2. Check the disc rotor runout.
(1) Remove the caliper body assembly. Rear Disc Brake Assembly > REMOVAL">
(2) Secure the disc rotor by tightening the five wheel nuts.
(3) 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.
Disc rotor runout limit:
0.05 mm (0.0020 in)

(4) 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.
Disc rotor runout limit:
0.05 mm (0.0020 in)

3. If the disc rotor runout exceeds service limit, resurface the disc rotor.
4. Check the disc rotor thickness after resurfacing. Rear Disc Rotor > INSPECTION">
2. DISC ROTOR THICKNESS CHECK
1. Set a micrometer 10 mm (0.39 in) inward from the disc rotor outer perimeter, and then measure the disc rotor thickness (A).

Type of disc rotor | Standard | Wear limit | Disc rotor outer diameter | |
Disc rotor thickness (A) | Solid disc | 10 mm (0.39 in) | 8.5 mm (0.33 in) | 274 mm (10.79 in) |
2. If the wear limit is exceeded in the inspection, replace the disc rotor.
