Wilwood Rear Black D154 Parking Brake Kit, Big Ford New Style Housing, 2.50-Inch Offset; Conditional Lincoln Town Car 1990 Application

Black D154 twin-piston calipers and plain 12.19-inch rotors form this Wilwood rear parking-brake conversion for the Big Ford New Style housing end. Internal shoes provide parking operation inside the rotor hats, separate from hydraulic braking. The listed 1990 Lincoln Town Car application requires confirmation of this exact axle configuration rather than an assumption of factory fit. 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

Use DS854 and the axle worksheet to measure flange bolt spacing, bearing dimensions and the 2.50-inch offset. A Town Car badge or year does not establish that the required housing end is installed. Obtain Wilwood confirmation for the actual axle before ordering. Check flange diameter, studs and nearby suspension, then arrange separate parking cables and compatible hoses. A 16-inch wheel is the conditional catalog starting point, with some 15-inch designs possible only after the full profile fits.

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