An illustrative example embodiment of an elevator brake device (30) includes a brake member (40) configured to move into a braking position to resist movement of an elevator car (22) associated with the brake device. A plurality of actuators (42, 44, 46, 48) 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 (32) determines a number of the actuators to activate based on a determined load of the elevator car associated with the brake device.
