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.
