Product details

The red-caliper plain-face package converts the specified New Style Bronco axle end to rear disc service brakes with an internal parking mechanism. Its one-piece drum/rotors keep the friction ring and parking drum together, with the brackets and shoe assemblies supplied for the measured axle interface. For this conversion, component matching remains essential. Its manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems for motorsport, street-performance and specialized applications; its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines selected to work within a complete system.
