Wilwood Red Front Superlite Brake Kit, 12.88-Inch Drilled/Slotted Rotors for Bronco Disc Spindles (1976–1977)

This red-caliper Bronco front conversion uses drilled-and-slotted rotor faces and six-piston hydraulic calipers. The included hoses serve the specified original disc-spindle layout rather than the earlier drum arrangement. Camarillo, California is home to Wilwood Engineering, founded by Bill Wood in 1977. Wilwood designs and manufactures disc brake systems, with calipers, brake rotors, master cylinders, fittings, valves and lines serving motorsport, street-performance and specialized uses. Select individual parts to meet the needs of the complete brake system.
