The manufacturer, Wilwood Engineering, was founded by Bill Wood in 1977 and is based in Camarillo, California. It designs and manufactures disc systems and component parts across motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and lines. Those individual parts must be selected in the context of the complete brake system.

Fitment & Compatibility

Match the actual hub spindle and suspension before choosing by vehicle badge. The modern Mustang entries and earlier Ridetech-equipped Falcon, Comet, F-100 and Mustang applications have distinct conditions. Verify DS1271 clearances and the front line-kit connections on the installed chassis.

Models represented in the detailed applications: Falcon, Comet, Mustang, F-100. Each is subject to its individual year, trim and brake/suspension condition. Use the fitment table below to confirm year, model, trim and brake or suspension options.

Choose any alternative flexline for the actual route and chassis fittings, with enough travel and the correct flare connections.

PMB Performance brings over 20 years of parts and fitment experience. Send the vehicle details and installed brake/suspension configuration if you need help checking this package.
