Wilwood Red Four-Piston Front Brake Kit for Selected Ford Falcon/Fairlane/Maverick/Mustang/Ranchero/Torino and Mercury Cyclone/Cougar/Comet/Montego, Drilled Dynalite Rotor/Hubs (1970–1974)

This red-caliper package converts the specified later Ford and Mercury front spindles using drilled-and-slotted rotor/hub assemblies. Four opposed pistons operate each Dynalite-M caliper, while the supplied brackets and line kit provide the mechanical and hydraulic interfaces for the matched installation. The kit comes from Wilwood Engineering of Camarillo, California, established in 1977 by Bill Wood. Wilwood designs and manufactures disc brake systems and components for motorsport, street-performance and specialized installations. Alongside calipers and brake rotors, its range includes master cylinders, valves, fittings and brake lines, all requiring selection around the complete system's operating requirements.

Fitment & Compatibility

The application is defined by the spindle actually on the car. Confirm the later 1970 production arrangement where listed, the Mustang disc-brake exceptions and the mounting-hole pattern. Check full steering movement after routing the hoses and confirm wheel clearance with DS1035.

A master-cylinder change can require modification of the existing pushrod assembly. The separate universal parking-cable note applies only if the rear brakes are also being converted; this front kit does not supply a rear parking-brake conversion.

Where a different chassis connection or length is needed, universal flexline references are 220-7056 (14 inches), 220-7699 (16 inches) and 220-8307 (18 inches). These are alternatives to assess, not additional sets included in the kit.

Use the fitment table below for the complete model, year, submodel and brake-option conditions; every listed condition must match the installed vehicle.
