Wilwood Front Dynalite-M Disc Kit for Selected Cadillac 1957–1960 Models, Black Calipers, Integral 11.88-Inch Rotors and Hoses

Selected late-1950s Cadillac front drum assemblies can be converted with black four-piston Dynalite-M calipers and plain vented iron rotor/hubs. The integral hub design uses the specified 5 x 5 wheel circle, and the kit supplies the corresponding front flexlines. Wilwood Engineering is based in Camarillo, California; Bill Wood founded the company in 1977. Disc brake system design and manufacturing includes calipers, rotors, master cylinders, pressure valves, fittings and brake lines for motorsport, street-performance and specialized applications. Component selection must account for how the complete brake system mounts, operates and balances.
