For 1990-2009 cars

1. Remove the wheel and install a wheel bolt and spacer across from the rotor retaining screw.
2. Fasten a dial indicator to the steering knuckle so that the indictor plunger contacts the rotor about 10 mm (0.40 in) from the rotor edge.
3. Zero the dial indicator.
4. Rotate the rotor one complete revolution and observe the total indicated runout (TIR).

Brake Rotors (Lateral Runout)

• | Front: 0.030 mm (0.001 in)

• | Rear: 0.030 mm (0.001 in)

Lateral runout of the rotor, if excessive, can often be improved by cleaning dirt and rust from the hub and the rotor mating surfaces and/or indexing the rotor on the hub one or two bolt positions from the original position. If the lateral runout cannot be corrected by indexing the rotor, check the hub and the bearing assembly for excessive lateral runout. If the hub and bearing assembly lateral runout exceeds, 0.065 mm (0.002 in) front and 0.040 mm (0.0016 in) rear, replace the hub and the bearing assembly. If the lateral hub and bearing runout is within specifications, refinish or replace the rotor as necessary.
