4. Calculate the difference between the highest and lowest thickness measurements recorded to obtain the amount of thickness variation.
5. Compare the thickness variation measurement to the following specification:
Brake rotor maximum allowable thickness variation: 0.025 mm (0.001 in)
Important: Whenever a brake rotor is refinished or replaced, the assembled lateral runout (LRO) of the rotor must be measured to
ensure optimum performance of the disc brakes.
6. If the brake rotor thickness variation measurement exceeds the specification, the rotor requires refinishing or replacement.
