Wilwood Black Dynalite Rear Parking Brakes for Old-Style Big Ford — 2.36-inch Offset, 12.19-inch SRP

A black SRP brake package brings an internal-shoe parking brake to the old-style Big Ford end. The supplied black powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors are configured for Big Ford Old Style, 2.36-inch offset. Wilwood Engineering began in 1977 under founder Bill Wood and is based in Camarillo, California. The company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized vehicles. Calipers, rotors, master cylinders, valves, fittings and brake lines must be selected around the needs of the complete system.

Fitment & Compatibility

Choose this package by the old-style Big Ford housing end and the measured 2.36-inch axle offset. The word Ford alone is not sufficient: new-style/Torino and Small Ford ends use different bracket arrangements. Compare the mounting flange with DS419 and measure from the axle flange using Wilwood’s worksheet before dismantling the existing brakes. The application list includes a 1990 Lincoln Town Car row, but a changed axle assembly must still satisfy the specified end and offset. This conversion provides rear service discs plus an independent internal-shoe parking brake. Plan the cable connection as part of the installation; the brake kit does not include the cable assembly or hydraulic flexlines. A matching wheel bolt circle is only one check and does not establish housing compatibility.

Check the actual wheel against the manufacturer template, including the inner barrel and back of the spokes. A nominal wheel diameter by itself does not guarantee clearance.

Use the complete vehicle row and its application notes below to check model year, trim and original brake equipment.

Package and installation requirements

• Service braking uses the four-piston calipers. A separate set of shoes works inside the drum sections of the one-piece rotors to hold the vehicle when parked.
• Allow for hydraulic hoses and a parking-cable connection in addition to this kit. Wilwood lists universal cable assembly 330-9371, which may need vehicle or cable modifications.
