Abstract: A system includes a brake torque request module, a brake control module, and a diagnostic module. The brake torque request module is configured to generate a brake torque request based on a brake pedal position during a braking event. The brake control module is configured to apply friction brakes on a wheelset of a vehicle to satisfy the brake torque request during the braking event. The wheelset includes less than all wheels of the vehicle. The diagnostic module is configured to detect a fault in a brake rotor on a wheel in the wheelset based on vehicle operating conditions measured during the braking event.
