J 8001 Dial Indicator Set
Check the lateral runout with the wheels still installed on the vehicle.This gives a much more accurate reading of the total indicated runout (TIR) under real braking conditions. If equipment is not available to perform the measurement with the wheels installed, measure with the wheels removed but with the brake caliper still installed.
In some cases, excessive lateral runout can be improved by indexing the brake rotor on the hub that is one or two bolt positions from the original position. If you cannot correct the lateral runout by indexing the brake rotor, check the hub and bearing assembly for excessive lateral runout or looseness. If the hub and bearing assembly lateral runout exceeds 0.040 mm (0.0016 in), replace the hub and/or bearing assembly as necessary. If the brake rotor's lateral runout is not within specifications,refinish or replace the rotor as necessary.
