GMA 4 Piston Front Brake Caliper for 2008-2020 Harley-Davidson FL Models
Upgrading a touring Harley’s front brake to a four-piston setup changes the whole character of front-end deceleration – from a single-point grab to a progressive, even squeeze that gives the rider far more control over how fast the bike slows. The GMA four-piston caliper delivers that progression on FL touring platforms where the factory hardware leaves real stopping potential untapped.
