Wilwood Rear D154 Parking Brake Kit, Chevelle/442/Beaumont/Camaro/Apollo (1964–1974), Staggered-Shock 12-Bolt, Black Calipers and Plain Rotors

Black D154 calipers and plain 12.19-inch rotors form this Wilwood rear parking-brake package for the specified staggered-shock 12-bolt housing configuration. The two-piston hydraulic calipers work with internal parking-shoe assemblies and a measured 2.81-inch axle offset. Vehicle model names are conditional references; the actual flange and shock arrangement determine the rear installation and must be checked before ordering. 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

Match the 12-bolt special housing-end dimensions and axle offset with the manufacturer's drawing. This package places the right-hand caliper behind the axle and the left-hand caliper ahead of it to suit staggered shocks; both are rear brakes. Front Ridetech spindle notes in the application table cannot establish rear-axle compatibility. Choose hydraulic lines and parking cables separately, compare the wheel with the full clearance template and verify balance with the front brakes.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
