An elevator car or counterweight, comprising a frame, the frame comprising an upright structure in which a safety brake is mounted so as to allow for lateral movement of the safety brake relative to the upright structure; at least a first vertically or obliquely extending cantilever spring; wherein a first end of the first cantilever spring is mounted to the upright structure; and wherein the first cantilever spring is arranged such that a point remote from the first end provides a biasing force to the safety brake when the safety brake moves away from a default position. As the safety brake is mounted to allow for lateral movement relative to the frame, the safety brake essentially floats relative to the car or counterweight. Thus, in operation, if there is an imbalance in the car or if the safety brake is otherwise not optimally aligned with the rail against which it brakes, the safety brake can move so as to attain an optimal braking position rather than moving the whole mass of the car or counterweight. After braking, it is desired to return the system to normal use, and thus to return the safety brake to its default position. The use of one or more cantilever springs to provide a biasing force to return the safety brake to the default position is advantageous as the cantilever arrangement takes up very little lateral width. In smaller elevator systems, the available width in the frame upright is very limited.
