A system comprising a cable (12) held in suspension and a trolley (10) traveling along the cable (12). The trolley (10) may include a brake pad (88) positioned to contact the cable (12). The brake pad (88) may include a plurality of segments (89) contacting the cable (12). A first such segment (89) may be formed from a first material. A second such segment (89) may be formed from a second material, distinct from the first material. The sequence, composition, gaps, and the like of the plurality of segments (89) may be selected to provide a desired resistance to wear, frictional coefficient, all-weather braking, and the like.
