Wilwood Front Black Superlite 6R Brake Kit for Ford Bronco Dana 44 Disc Spindles (1976–1977), 12.88-Inch Rotors

Black Superlite 6R calipers and plain 12.88-inch rotors replace the documented factory-disc Bronco front brakes. Hats retain the compatible hubs, and the kit supplies the specified flexible hoses. Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.
