Wilwood Black Six-Piston Front Brake Package, 14-Inch GT Rotors for Bronco Dana 44 Disc Spindles (1976–1977)

Black six-piston calipers clamp slotted 14-inch rotors in this Bronco factory-disc front conversion. Compatible original hubs are retained, and the specified flexible hoses are included. Bill Wood founded Wilwood Engineering in 1977, and the manufacturer is based in Camarillo, California. Wilwood designs and manufactures disc brake systems alongside calipers, master cylinders, rotors, fittings, brake lines and valves. The motorsport, street-performance and specialized ranges depend on components selected to work within a complete braking system.
