Red low-profile calipers and plain 11-inch rotors fit the specified Big Ford interface. Check the 2.36-inch axle offset and internal parking setup. Disc brake system design and manufacturing are Wilwood Engineering’s focus. Bill Wood founded the Camarillo, California company in 1977; its range spans brake rotors, master cylinders, calipers, fittings, valves and brake lines for motorsport, specialized and street-performance applications. The choice of individual components depends on the complete brake system.

Fitment & Compatibility

Select by the documented Big Ford rear housing flange and a 2.36-inch axle-flange offset, measured from the wheel-side axle-flange face to the housing-flange face. This geometry is distinct from the new-style Big Ford and Small Ford kits. Stock 1990 Lincoln Town Car fitment is unverified; the vehicle entry below does not establish the required axle geometry. Confirm the actual housing, axle register and offset before treating that vehicle assignment as verified. The 11.00 × 0.81-inch one-piece iron rotors incorporate parking hats; internal shoes are included, while cables, clevises, adapters and hoses are separate. Check the maximum 6.61-inch axle-flange diameter, specified chamfer and 3.06-inch rotor register; a 2.80-inch register adapter is supplied. Larger studs may require rotor-hole machining; 0.520-inch holes are clearance dimensions, not a thread. Match the wheel template even where nominal 14-inch guidance applies.

Listed models: Town Car. See the supplied table below for each year, submodel and equipment condition.
