Tools Required
- Raise the vehicle. Support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire/wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Remove the caliper. Refer to
Brake Caliper Replacement
.
- Invert and install all wheel nuts to retain rotor.
- Fasten the J 26900-13
and the J 8001
to the strut. Ensure that the indicator button contacts the brake
rotor 10 mm (0.39 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 0.05 mm (0.0020 in).
- If the lateral runout exceeds specifications, clean wheel hub
and rotor mating surfaces.
- Measure the lateral runout again.
- If lateral runout still exceeds specifications, index the rotor
on the hub one or two bolt positions from the original position.
- Measure the lateral runout again.
- If the lateral runout still exceeds specifications, inspect the
bearing play and axle hub deviation. Refer to
Wheel Bearings Diagnosis
in Suspension General Diagnosis.
- Measure the lateral runout again.
- If hub and bearing assembly are within specifications, refer to
Brake Rotor Tolerance
.
- If the rotor surface finish depth does not meet specifications,
refer to
Brake Rotor Thickness Variation Check
.
- Replace a rotor that does not meet the specifications for thickness
variation, finish depth, and lateral runout. Refer to
Brake Rotor Replacement
.
