Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.

Fitment & Compatibility
Confirm the caliper identification, piston diameter and available cavity depth before ordering. The listed dimensions describe the replacement component and do not establish universal caliper fitment. The Thermlock assembly combines a stainless heat shield with a coated aluminum shell to reduce heat transfer toward the caliper body and fluid. Use the complete specified design rather than substituting by diameter alone.
