Wilwood Plain Rear Parking Brake Conversion, Red D154 Calipers, Chevelle/442/Beaumont/Camaro/Apollo (1964–1974), 12-Bolt Staggered Shocks

Plain-face 12.19-inch rotors pair with red D154 calipers in this Wilwood rear parking package. The kit includes internal parking-shoe assemblies and uses the specific 2.81-inch-offset 12-bolt special housing arrangement for staggered shocks. It is an axle-geometry conversion, with the actual flange and bracket positions needing verification rather than an unconditional direct-fit claim for the vehicle table. 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 for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Check the flange dimensions, axle offset and staggered shock positions on the actual rear axle. Follow the instructions for right-caliper rearward and left-caliper forward mounting around that axle. Front-spindle notes cannot establish this rear configuration, so confirm those vehicle applications independently. Select hydraulic lines and parking cables to suit the installation, then set the internal shoe clearance. Use the complete wheel drawing and verify caliper centering, rotor release and front/rear hydraulic proportioning after assembly.
