Wilwood Red Front GT Rotor Brake Kit for Bronco Dana 44 Disc Spindles (1976–1977), 14-Inch Superlite Package

The GT-slotted option for this Bronco front kit combines red six-piston calipers with 14-inch vented rotor rings. Its supplied hats and hoses are matched to the factory-disc Dana 44 configuration. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and builds disc brake systems for motorsport, street-performance and specialized uses, including calipers, rotors, master cylinders, valves, fittings and brake lines. Each part must match the requirements of the whole braking arrangement.
