Wilwood Rear Red Dynalite Brake Kit with Plain Rotors and Parking Brake, AMC Javelin/Javelin AMX Axles with 2.60-Inch Offset

Plain vented iron rotors and red Dynalite calipers form this Javelin/Javelin AMX rear package. Its internal parking brake requires a separate cable system, and the axle flange determines the correct bracket fit. Established in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems. Its master cylinders, calipers, brake rotors, lines, fittings and valves support motorsport, street-performance and specialized applications, with each component selected for its role in the complete brake system.
