Before ordering replacement parts for STR-60 Trophy Sport calipers, identify if they are old (Gen1-3) or new (Gen4) calipers. To do this, examine inside the caliper body to determine how the pads are held in place.
Gen1 to Gen3 calipers use stainless steel abutment plates, bolted to thick, metal blocks.
Gen4 calipers use abutment plates that screw directly to the caliper. No blocks are used.
