Disclosed herein are systems and methods including an electromechanical brake used downhole to impart dynamic or static braking capabilities while absorbing or otherwise reducing shock loads. The electromechanical brake may be used for a downhole electromechanical linear actuator to control a valve for the production of subterranean fluid. In some examples, it may be desirable for an electromechanical linear actuator to maintain a retracted position during certain safety and/or maintenance operations. The electromechanical brake includes a brake housing, a first armature rotatably disposed in the brake housing, a second armature rotatably disposed in the brake housing for rotation by a motor, an electrical coil energizable to urge the second armature into axial engagement with the first armature, and a rotational spring for biasing the first armature to a neutral rotational position relative to the brake housing while allowing a limited rotation of the first armature relative to the brake housing.
