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