A self-energizing brake for a motor has a moving brake section, including a brake friction material located on a portion of a face thereof perpendicular to its axis of rotation which is automatically urged toward a brake mating surface upon the motor coming to a stop, thereby automatically energizing the brake, and which is automatically urged away from the brake mating surface upon the motor beginning its rotation, thereby automatically de-energizing the brake.
