Wilwood Red Rear SRP Parking-Brake Package, Dynapro Dust-Boot Calipers for Small Ford Axles with 2.66-Inch Offset

Red calipers and SRP rotor surfaces identify this four-piston rear assembly for Small Ford housing ends. Its internal parking brake requires suitable cables, while the 2.66-inch offset positions the rotor in the bracket. Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.

Fitment & Compatibility

Check the actual axle assembly's axle-end pattern and flange-to-wheel-face measurement. This package cannot be chosen from the vehicle name without confirming those dimensions. 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.
