Wilwood Red Low-Profile Rear Brakes for Big Ford Axles with 2.36-Inch Offset and Drilled 11-Inch Rotors

Red Dynapro calipers, drilled parking-hat rotors and internal shoes form this rear conversion. Match the actual axle flange, register and 2.36-inch offset. Bill Wood founded Wilwood Engineering in 1977, and the manufacturer is based in Camarillo, California. Wilwood designs and manufactures disc brake systems alongside calipers, master cylinders, rotors, fittings, brake lines and valves. The motorsport, street-performance and specialized ranges depend on components selected to work within a complete braking system.

Fitment & Compatibility

The red four-piston, drilled-and-slotted version uses the Big Ford housing-flange layout and exactly 2.36 inches of axle-flange offset. Verify that distance between the wheel-side axle flange and housing flange, then check the housing pattern, bearing arrangement and axle center register. Stock 1990 Lincoln Town Car compatibility is unverified. Confirm the physical axle interface before relying on the listed vehicle entry. The kit supplies 11.00 × 0.81-inch one-piece iron parking-hat rotors and internal parking shoes; hydraulic hoses, parking cables, clevises and vehicle cable adapters are extra. Rotor centering uses a 3.06-inch center or the supplied 2.80-inch register ring. The axle flange must meet the 6.61-inch maximum and specified chamfer. Check stud clearance and any required rotor-hole machining, then verify the wheel drawing rather than relying on the conditional 14-inch diameter guidance.
