Wilwood Rear Red Dynapro Plain-Rotor Brake Kit, Small Ford Flange and 2.66-Inch Axle Offset

This rear Small Ford conversion supplies red dust-boot calipers and plain vented rotors around a mechanical parking-brake assembly. It retains the specified 2.66-inch flange offset rather than the shorter-offset bracket geometry. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility

Compare the actual actual rear axle-end drawing with DS1001. Check the flange register and wheel pattern as well as the offset, then select the hoses and parking-cable fittings needed by the car. The application table includes a 1990 Lincoln Town Car row, but Wilwood identifies this kit by axle flange and offset. Stock Town Car axle compatibility is not established; confirm the actual or custom axle measurements before purchase.

The installation drawing specifies a 2.80-inch axle register and the corresponding centering-adapter arrangement. Check the housing pattern and axle offset, then confirm the flange fits within the 6.61-inch diameter limit with its 0.050-inch x 45-degree chamfer.

Inspect shock-to-brake clearance as well as the axle dimensions; the installation instructions note that some shock arrangements may need modification or relocation.

Hydraulic hoses/fittings and parking-brake cables, adapters and cable hardware are not included. Choose a compatible cable arrangement for the internal parking brake; universal cable systems may require vehicle or cable modifications.

Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.
