Product details
The wider thin-rotor Kart/Junior Dragster caliper uses a nominal 0.19-inch rotor opening in this selected configuration. It has two 1.00-inch stainless pistons and includes the brake pads described by Wilwood for the racing assembly. Internal fluid routing and a compact billet aluminum housing keep the hydraulic component close to the rotor. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility
Check the chassis bracket’s 2.25-inch centers and the caliper’s mounting offset with the intended rotor. Match the working thickness limits to the rotor; the family’s other rotor openings are separate versions. Verify pad contact across the rotor, a suitable master cylinder and room for the inlet fitting before installing on a kart or junior dragster.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
