Wilwood Front 11.50-Inch Plain Brake Kit, Chevrolet Tri-Five ProSpindle Cars (1955–1957) with Red FDL-M Calipers

Red calipers and 11.50-inch plain face rotors are the selected configuration. Forged Dynalite-M four-piston front calipers work with 11.50-inch integrated hub/rotor castings in this Wilwood ProSpindle conversion. Bearings, seals and brake pads are supplied for the documented Tri-Five spindle arrangement. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Each component must suit the surrounding brake system.
