Abstract: An elevator brake wedge is provided and includes an elongate body having first and second generally opposed major surfaces and first and second generally opposed minor surfaces. The second minor surface has a greater length than the first minor surface. Each of the first and second major surfaces extends between corresponding first and second ends of the first and second minor surfaces, respectively. The second major surface defines low-friction film securing grooves extending from a plane of the second major surface into the elongate body.
