Product details
This front kit uses red Dynapro calipers, plain vented rotors and five-lug hubs on the documented Ford/Mercury disc spindles. The hub conversion must be considered before retaining or ordering wheels. 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
Use the appropriate Mustang II, Pinto or Bobcat year row and compare the disc spindle with DS1019. Check for interference at the original caliper ears before deciding whether trimming is needed. Four-lug wheels are incompatible with these hubs; inspect mounting-pad contact and hose routing.
Documented model groups, subject to each year, submodel and spindle/axle qualification: Ford Mustang II, Pinto; Mercury Bobcat.
Requires the documented original disc spindle and compatible five-lug wheels. Four-lug wheels are incompatible. DS1019/DS1020 calls for limited removal of original caliper ears only where they interfere; preserve the bracket mounting holes.
Check how the wheel rests on the hub before evaluating spoke clearance. Part 300-11961 (listed in the installation parts list) 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 includes 5 lug hubs. Not applicable to 4 lug vehicles.
Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.
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.
