GMA Engineering 2-Piston Custom Rear Brake Calipers for 1973-2000 Harley-Davidson

GMA Engineering 2-Piston Custom Rear Brake Calipers for 1973-2000 Harley-Davidson

Custom rear brake geometry on vintage and modified Harley-Davidson platforms rarely accommodates the same caliper across different model years and frames. GMA solved this by developing a family of model-specific two-piston calipers – each one engineered to a specific mounting geometry so the caliper seats correctly and rear braking functions as it should.
