Abstract
An adjustment mechanism for a vehicle brake uses an electric motor to adjust brake clearance based on brake temperature and wheel speed. A temperature sensor transmits brake temperature data to a controller. If a brake is dragging during non-braking events, the controller identifies an increase in brake temperature and actuates the electric motor to increase brake clearance. The controller also adjusts brake clearance to accommodate for brake wear. When wheel speed is above a predetermined speed value, the controller actuates the electric motor to move a non-rotating brake component toward a rotating brake component until a predetermined temperature increase is sensed. Once the predetermined temperature increase is identified, the electric motor moves the non-rotating brake component away from the rotating brake component to provide an optimized brake clearance.
