ELEVATOR MACHINE BRAKE CONTROL An illustrative example embodiment of an elevator brake device includes a 5 brake member configured to move into a braking position to resist movement of an elevator car associated with the brake device. A plurality of actuators are associated with the brake member and selectively controllable to apply a force to cause the brake member to move into the braking position. A brake controller determines a number of the actuators to activate based on a determined load of the elevator car 10 associated with the brake device.
