Product details
Red powder coating identifies this Forged Dynalite-M brake caliper, supplied as an individual hydraulic component. Four stainless pistons act on the pads, while internal fluid passages keep the hydraulic connection within the caliper body. The rotor opening belongs to the nominal 1.00-inch-width configuration, with a published operating thickness range of 0.88–1.04 inches. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
A replacement must reproduce the existing pad position over the rotor rather than merely share its red finish. Check the mounting ears, bracket alignment and wheel-spoke space before assembly. Use the specified pad shape and select a friction compound for the complete brake system; the piston size also needs to agree with the intended front-to-rear hydraulic balance.
