Brake Rotor Lateral Runout Check. Chevrolet Metro 2001

For 1990-2009 cars

#### Tools Required

• | J 8001 Dial Indicator Set

• | J 26900-13 Magnetic Base

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
3. Remove the caliper. Refer to Brake Caliper Replacement .
4. Fasten J 26900-13 and J 8001 to the strut so that the indicator button contacts the brake rotor (1) about 10 mm (0.39 in) from the rotor edge.
5. Set J 8001 to zero.
6. Move the rotor one complete revolution and observe the total indicated runout.

The maximum rotor lateral runout is 0.10 mm (0.004 in). If the lateral runout exceeds specifications, clean the wheel hub and rotor mating surfaces and measure the runout again.

If the lateral runout still exceeds specifications, index 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 bearing assembly for excessive play. If the hub and bearing assembly are within specifications, refer to Brake Rotor Tolerance and Surface Finish.

Refinish or replace a rotor that does not meet the lateral runout specifications.
