Wilwood Front Black Dynapro Dust-Boot Kit, 12.19-Inch Plain Rotors for Documented Ford/Mercury Spindles

This larger Ford/Mercury front kit uses black four-piston dust-boot calipers, 12.19-inch plain rotors and aluminum hubs. It preserves the documented spindle-specific mounting requirements rather than making all original disc and drum versions equivalent. Bill Wood founded Wilwood Engineering in 1977, and the manufacturer is based in Camarillo, California. Wilwood designs and manufactures disc brake systems alongside calipers, master cylinders, rotors, fittings, brake lines and valves. The motorsport, street-performance and specialized ranges depend on components selected to work within a complete braking system.

Fitment & Compatibility

Match the actual three- or four-hole spindle configuration to DS1012. The disc-spindle holes require the specified drilling and tapping, with V8 and build-date limits retained for the relevant application rows.

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.

Check how the wheel rests on the hub before evaluating spoke clearance. Part 300-11961 (sold separately) is the specified 6.60-inch-diameter, 0.20-inch-thick steel spacer for overhanging wheel contact surfaces. The separate 300-10716 hub shield is recommended for stamped steel wheels without overhang and measures 6.15 inches by 0.09 inch.

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.
