Tools Required
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Remove the caliper. Refer to
Brake Caliper Replacement
.
- Install all the wheel nuts in order to retain the rotor.
- Fasten a J 26900-13
and a J 8001
to the strut (1) so that the indicator button contacts the
brake rotor (2) 25 mm (0.98 in) from the rotor edge.
- Zero the J 8001
.
- Move the rotor one complete revolution and observe the total indicated
runout.
The maximum rotor lateral runout is 0.15 mm (0.006 in).
- If the lateral runout exceeds specifications, clean the wheel
hub and rotor mating surfaces, and measure the lateral 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,
inspect the hub and bearing assembly for runout. Refer to
Tire and Wheel Vibration
in Vibration Diagnosis.
- Inspect the hub and bearing assembly for looseness. Refer to
Wheel Bearings Diagnosis
in Suspension General Diagnosis.
- If the hub and bearing assembly are within specifications, measure
the depth of the scoring on the rotor. Refer to
Brake Rotor Tolerance
.
- Refinish or replace any rotor that does not meet the lateral runout
specification. Refer to
Brake Rotor Refinishing
or to
Brake Rotor Replacement
.
