ROTOR CONDITION MONITORING SYSTEM AND METHOD

A method of monitoring a rotor of a motor vehicle having a caliper assembly driven by a motor for braking the vehicle includes detecting at least one harmonic response during a braking operation indicative of the interaction between the caliper assembly and the rotor. The at least one harmonic response is evaluated during the braking operation and an operator of the vehicle is notified of a condition of the rotor based on the evaluation.
