Product details

Red four-piston Superlite calipers are paired with drilled-and-slotted rotor rings on the specified Bronco parking hats. The New Style flange and measured axle offset position the caliper and parking components; a shared wheel bolt pattern alone does not confirm compatibility. Camarillo, California is the home of Wilwood Engineering, the disc brake systems and components manufacturer founded by Bill Wood in 1977. It designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. The requirements of the complete brake system determine which individual components are appropriate.
