A selectively operable braking device for an elevator system (10). The braking device includes a safety brake (24) adapted to be wedged against a guide rail (20) when moved from a non-braking state into a braking state. Also included is an engagement mechanism (60) moveable between an engaged position and a non-engaged position, the engagement mechanism (60) comprising bar pinions (62a-62d) each having teeth and connected to at least one of the other bar pinions with a meshed engagement of the teeth, the engagement mechanism (60) configured to move the safety brake (24) between the non-braking state and braking state when the engagement mechanism (60) moves between the non-engaged position and the engaged position. Further included is a plurality of magnetic brake pads (44a-44d), each of the brake pads coupled to one of the bar pinions (62a-62d), wherein movement of one of the brake pads (44a-44d) into the engaged position causes movement of the other magnetic brake pads (44a-44d) into the engaged position.
