Wilwood Red Front Dynapro Dust-Boot Brake Kit with 12.19-Inch SRP Rotors, Ford/Mercury Spindle Conversion

Red dust-boot calipers operate against drilled-and-slotted 12.19-inch rotors in this Ford/Mercury package. Aluminum hubs carry the documented dual wheel patterns, and each spindle layout uses its specified attachment hardware. Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems from Camarillo, California. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Individual components must be selected for the complete brake system.

Fitment & Compatibility

Check DS1012 and the exact application row, including any V8, early-build or GT350/GT500 qualification. Do not overlook the drilling and re-tapping required for the documented disc-spindle mounting arrangement.

Documented model groups, subject to each year, submodel and spindle/axle qualification: Ford Falcon, Ranchero, Fairlane, Mustang, Torino, Maverick; Mercury Comet, Cyclone, Caliente, Cougar, Montego. Application distinctions include V-8 Spindle Only; Disc Brake V-8 Spindle Only; Drum Brake V-8 Spindle Only; Drum Brake Spindle; Disc Brake Spindle; Drum Brake Front Spindle; Drum Brake Front thru 8/24/69; Disc Brake GT350 & 500 only.

The 1970 Falcon and Maverick drum rows are restricted to production through8/24/1969; the 1970 Mustang disc row is GT 350/GT 500 only. Earlier Falcon, Ranchero, Comet and Cyclone rows retain their V8-only restrictions.

If the wheel contact surface overhangs the hub face, use steel spacer 300-11961, specified as 6.60 inches in diameter and 0.20 inch thick (sold separately). Stamped steel wheels without that overhang should use the separately sourced hub shield 300-10716, measuring 6.15 inches across and 0.09 inch thick.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.

Flexline kits: 1965-67 use 220-6471 (18"), 1968-up use 220-9195 (18").

A separately selected master cylinder may require modification of the existing pushrod assembly; it is not supplied in this brake kit.

An independently added universal parking-brake cable system may require cable or vehicle modifications. It is separate from this front service-brake kit.

Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.
