Performance Machine 4 Piston Front Calipers with Differential Bore – Brake

The "137x4B" type caliper is the most powerful 4 piston caliper available anywhere. This differential bore, direct bolt on caliper has its design roots in endurance road racing where power and above all "feel" are of paramount importance. The differential bore sizes uses a larger trailing piston to compensate for uneven pad wear and retains feel under high heat situations giving the smoothest action and most powerful braking possible. These calipers bolt directly to the front fork and work with stock or aftermarket 11 1/2" or 11.8" discs (as indicated below). Order 1 left caliper for single disc and 1 right and 1 left for dual discs.
