Product details

Red Dynapro four-piston calipers clamp the drilled-and-slotted iron rotors in this Bronco rear conversion. The mechanical parking shoes are housed inside the rotor drums; they require a separate compatible cable/clevis connection to the vehicle's hand or foot control. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems and their components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on choosing those parts around the complete braking system.
