Abstract
A brake actuator system may comprise a brake actuator comprising a ball screw, a ball nut coupled to the ball screw, and a ram coupled to a ram end of the ball nut; a position sensor coupled to the brake actuator; a processor in electronic communication with the brake actuator and the position sensor; and a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations. The operations may comprise commanding the brake actuator to translate the ball nut in a first direction toward a brake stack; detecting the pusher reaching a furthest forward position; and commanding the brake actuator to translate the ball nut in a second direction opposite the first direction for a predetermined retraction distance.
