Disclosed is a brake assembly (200) for an elevator system, having: a housing (210) defining a housing cavity (2145), a housing forward end with a forward end opening (2150) into the housing cavity, and a housing aft end; a first magnet (2210) disposed in the housing cavity, near the forward end opening; a second magnet (2230) disposed in the housing cavity, between the first magnet and the housing aft end, and wherein the second magnet is configured to: reduce attraction between itself and the first magnet, whereby the first magnet moves at least partially through the forward end opening to engage a guide rail (109) that is metallic, thereby preventing vertical movement of the first magnet of the brake assembly, when magnetically connected to the rail, relative to the housing; and attract the first magnet to draw the first magnet into the housing cavity.
