Abstract
A system configured to assess health of a rotor of a friction brake configured to brake a wheel of a vehicle. The system includes a brake control module configured to actuate the friction brake at a target pressure sufficient to maintain the vehicle at a crawl speed. A diagnostic module is configured to, while the vehicle is at the crawl speed and the friction brake is at the target pressure: record rotational speed of the wheel; identify a change in the rotational speed of the wheel; and determine whether the change in the rotational speed of the wheel exceeds a predetermined threshold; generate a notification indicating that the rotor of the friction brake configured to brake the wheel is healthy; and generate a notification indicating that the rotor requires attention.
