Wilwood Red Rear Dynapro SRP Parking Brake Kit, Small Ford Flange with 2.50-Inch Axle Offset

The red calipers in this rear package use dust boots and four aluminum pistons each. Drilled-and-slotted rotors incorporate the drum-style parking brake, with the Small Ford flange determining the bracket fit. Founded in 1977 under Bill Wood, Wilwood Engineering operates from Camarillo, California. The company designs and manufactures disc braking systems and components, including calipers, master cylinders, brake rotors, fittings, valves and brake lines. Its motorsport, specialized and street-performance range requires individual parts matched to the complete braking arrangement.

Fitment & Compatibility

DS1002 identifies the 2.50-inch-offset axle-end arrangement. Confirm it against the actual axle assembly and obtain the separate parking-brake cable and hose components to complete the conversion. 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.
