Description
*Also Fits Narrow-glide with wire wheel
Our 500 series differential bore 4 piston caliper continues to be unmatched for performance and value. Utilizing a smaller diameter piston at the lead-in of the rotor and a larger piston on the trailing side provides optimum friction dynamics by equalizing the heat distribution throughout the brake pad to rotor interface. In addition, the differential bore ratio and total volumetric displacement are correctly sized to promote the best brake caliper respo
