Wilwood Rear D154 Parking Brake Kit, Chevrolet Chevelle/Camaro, Oldsmobile 442, Pontiac Beaumont and Buick Apollo (1964–1974), C-Clip 12-Bolt Axle, Black Calipers

This Wilwood rear package combines black D154 calipers, plain 12.19-inch rotors and internal parking-brake shoes for the specified C-clip 12-bolt axle. Its axle-flange offset range is 2.75–2.81 inches. The Chevrolet, Oldsmobile, Pontiac and Buick model entries must be checked for this rear geometry; their front drop-spindle details do not identify the rear axle. 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

Read DS860 and measure the actual axle-end flange, bearing arrangement, rotor register and offset. The Chevelle, Camaro, 442, Beaumont and Apollo rows include front Ridetech spindle options, which cannot establish fitment of this rear conversion. Obtain confirmation of the rear assembly before ordering. Cable linkage and hydraulic hoses are separate. Use the conditional 16-inch wheel profile and assess any proposed 15-inch wheel individually; sufficient diameter does not guarantee spoke clearance.

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