120-5499 - Product Description

Billet Go-Kart

Our Kart/Jr. Dragster Caliper is designed specifically for racing. A unique self retracting and adjusting piston system has been incorporated which enables the piston to retract as the brake line pressure is reduced. The caliper can be mounted on either side of the vehicle and comes in three rotor widths. At just 1.20 pounds, the caliper comes with high performance, high friction brake pads. Additional features include deep cup stainless steel piston for reduced heat transfer, cotter pin, pad retainer, internal fluid passage and blue anodized finish. A specifically designed master cylinder is also available for use with this caliper.
