Wilwood Rear Red Dynapro Parking Brake Package, 11-Inch SRP Rotors, AMC Javelin/Javelin AMX (1971–1974)

Red low-profile Dynapro calipers provide the hydraulic braking in this Wilwood Javelin rear kit, while separate internal shoes provide the parking function. The selected rotors have drilled/slotted SRP faces and a vented 11-inch diameter. Matched BP-10 pads, mounting hardware and the AMC-specific parking assemblies complete the brake package. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

A 2.60-inch offset and the correct AMC flange are required. Read the individual Javelin and Javelin AMX entries, then verify those measurements directly because suspension or axle conversions can change them. Maintain the left-side shim stack during offset measurement and inspect clearance around the shocks. The instructions specify limits for axle flange diameter and the required stud arrangement. Add suitable hydraulic lines, parking cables and the specified original-style seal plate before installation; check the wheel profile as well as diameter.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
