5. Using a micrometer calibrated in thousandths-of-a-millimeter, or ten-thousandths-of-an-inch, measure and record the scoring depth of any grooves
present on the rotor friction surfaces.
6. Compare the groove scoring depth recorded to the following specification:
Specification
Brake rotor maximum allowable scoring: 1.50 mm (0.059 in)
7. If the brake rotor scoring depth exceeds the specification, or if an excessive amount of scoring is present, the rotor requires refinishing or
replacement.

Brake Rotor/Drum Balance Inspection
1. Support the vehicle drive axle on a suitable hoist.
2. Remove the tire and wheel assemblies from the drive axle.
WARNING: Refer to Work Stall Test Caution.
3. Reinstall the wheel nuts in order to retain the brake rotors.
4. Run the vehicle at the concern speed while inspecting for the presence of the vibration.
CAUTION: Do not depress the brake pedal with the brake rotors and/or the brake drums removed, or with the brake calipers
repositioned away from the brake rotors, or damage to the brake system may result.
5. If the vibration is still present, remove the rotors from the drive axle, then run the vehicle back to the concern speed.
6. If the vibration is eliminated when the brake rotors are removed from the drive axle, repeat the test with one rotor installed at a time. Replace the
rotor that is causing or contributing to the vibration concern.
