An electromechanical actuator 200 in an aircraft brake system may include a stationary body, an actuator drive unit 210 in an actuator drive unit housing 211, a ball screw 206 coupled to the actuator drive unit 210, and a ball nut piston 204 coupled to the ball screw 206. A supplemental back drive mechanism may be disposed between the ball screw 206 and the stationary body. The supplemental back drive mechanism may comprise a spring 220 and a clutch 230. The spring 220 may store back drive potential energy when the electromechanical actuator is actuated to drive the ball nut piston 204 forward, and may supply back drive energy to the retract the ball nut piston 204.
