Product details
Red AERO4 service calipers and drilled/slotted 14-inch rotors distinguish this Big Ford rear EPB package. The kit is configured for 6 x 5.5-inch drilling and includes the controls for its separate electric parking calipers. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. It designs and manufactures disc brake components and complete systems, from calipers and brake rotors to valves, master cylinders, fittings and brake lines. Motorsport, street-performance and specialized installations each require those components to be matched to the complete brake system.

Fitment & Compatibility
A six-lug Big Ford New Style axle at 2.50-inch offset is required for the 14-inch AERO4/EPB package. Check the large-bearing housing flange and 6 x 5.5-inch wheel-stud layout rather than selecting by vehicle name alone. The retained 1990 Town Car listing cannot establish that its original axle has the required conversion geometry.
Use DS1651 to confirm the 2.80-inch axle register, 6.61-inch maximum flange diameter and 0.050-inch x 45-degree chamfer. Both AERO4 service calipers and auxiliary EPB calipers need wheel clearance. Supplied electronic controls operate the parking system; purchase appropriate service-brake hoses/fittings separately and plan their routing before assembly.
Confirm the applicable vehicle entry and all numbered notes in the fitment table below.
The electric parking brake is for stationary parking, not an emergency-stop brake. Applying it while the vehicle is moving can lock the rear wheels and cause a skid. Follow the wiring and holding-test procedures in the manufacturer’s instructions.
