GMA Engineering 4-Piston Millennium Rear Brake Calipers 11.5 Inch for 1987-2007 Harley-Davidson

Rear brake performance on classic Big Twin platforms is often the weakest link in an otherwise capable brake system. The GMA Millennium four-piston rear caliper changes that equation – delivering clamping force that matches the front’s capabilities and giving riders the progressive, confidence-inspiring rear brake feel they have been missing.
