Wilwood Rear Plain Iron Rotor Kit with Red Dust-Boot Calipers, Small Ford Axles with 2.50-Inch Offset and Parking Brake

Red Dynapro calipers and plain vented iron rotors form the hydraulic portion of this Small Ford rear kit. A separately actuated internal parking brake is included in the rotor assembly, but its cable system is not. Wilwood Engineering designs and builds disc brake systems in Camarillo, California. Bill Wood established the company in 1977; it supplies brake rotors, calipers, master cylinders, valves, fittings and lines for specialized applications, street performance and motorsport. The complete brake system determines which individual components are appropriate.

Fitment & Compatibility

Match the measured housing-end geometry on the actual axle assembly to the 2.50-inch Small Ford configuration. Check shock clearance, axle centering and the wheel template before connecting the brakes. 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.

A maximum flange diameter of 6.61 inches and a 0.050-inch x 45-degree chamfer are specified for rotor clearance. The illustrated register is 2.80 inches; select the documented centering arrangement and match both axle offset and housing-end bolt pattern.

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.

Separate universal parking-brake cable kit 330-9371 is referenced for completing the internal drum-style parking brake; check its actual cable and vehicle adaptation.
