Wilwood Black Rear SRP Parking Brake Kit with Dust-Boot Calipers, Big Ford New Style 2.50-Inch Offset

A drilled-and-slotted rotor surface and black dust-boot calipers define this rear package. Its New Style Ford housing-end brackets and 2.50-inch offset must agree with the axle regardless of the vehicle badge. Established in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems. Its master cylinders, calipers, brake rotors, lines, fittings and valves support motorsport, street-performance and specialized applications, with each component selected for its role in the complete brake system.

Fitment & Compatibility

Confirm the specified axle flange on the actual axle assembly, including register centering and stud clearance. Inspect the wheel profile and plan separate hydraulic hoses and parking-brake cable adaptation. 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.

Measure the axle flange and register before mounting the brake: the flange must be no larger than 6.61 inches, with a 0.050-inch chamfer at 45 degrees. Use the instructions for the 2.80-inch register and its centering adapters as applicable, alongside the required offset and housing 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.
