Big Stopping Power for Little Rockets!
Wilwood's Jr. Dragster / Kart Brake 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.
The PS-1 Caliper is compact, lightweight (.93 pounds) and combines the strength of cast aluminum construction with a sleek low profile design. This caliper utilizes two stainless steel deep cup pistons to minimize heat transfer from the .30'' thick pad to the brake fluid while employing high temperature square piston seals to control piston retraction. Internal crossover brake fluid passages eliminate the use of external crossover tubes. The PS-1 fits rotors with diameters ranging from 6.00'' to 9.00'', thickness sizes from .15'' to .20''.
