Our giant 12” competition front disc brake kit is the largest vintage legal disc brake setup you can run with 15” wheels on any early Mustang.  Our kit comes with 12” x 1-1/4” directionally ventilated and stress relieved rotors, billet 6061 aluminum hats, and our large Kelsey-Hayes cast iron 4 piston (Lincoln) calipers.  Also included are billet steel caliper mounting brackets, all necessary grade 8 hardware, braided stainless steel front flex lines, and instructions.  Many years of development have gone into this state-of-the-art vintage legal brake setup.  The rotor/hat assembly is a “slide-on/slide-off” design allowing for easy maintenance.  Available with your choice of street or race compound carbon Kevlar pads for incredible stopping power.  These are the same brakes used on the Bud Moore Trans-Am Boss 302 Mustangs of 1969 and 70, made with today’s manufacturing technology.  Can be used with cast iron 1965-67 Mustang disc brake hubs or Cobra Automotive’s billet racing hubs.  Compatible with Ford spindles that utilize the standard 4 bolt mounting pattern found on 1965-73 drum brake and 1965-67 disc brake Mustang spindles (hubs and spindles are not included - see front suspension section).

Calipers: These are the largest four piston calipers Ford made for 60’s era applications, originally used on T-birds, Galaxies and Lincolns of the day.  Bud Moore used these same style calipers on his famous Trans-Am race cars that brought Ford the championship.  The pistons are large 1.950 diameter for superior braking force, made to our own specs for lighter weight and no groove for stock dust boots.  These 12" big brake calipers are machined and remanufactured in-house to our own specifications, fit with new custom seals, stainless steel bleeders, pad retainers and crossover lines.  Finished in a maintenance free, silver High-Temp thermal barrier coating. 

Rotors: Cobra Automotive’s own custom made 12” diameter directional vented rotors are a full 1-1/4” thick vs. the stock 13/16” thick 11” ones from the factory.  Thirty-six directional cooling vanes compliment this rotor's ability to dissipate heat, while the special stress relieving process reduces the possibility of warping during the break-in period.  Made of the same high quality material used in all forms of professional racing.

Rotor Hat: CNC machined from 6061 billet aluminum with the proper 1.59” offset for compatibility with our caliper and caliper mounting brackets.  This hat can be used with a stock cast iron 1965-67 Mustang disc brake hub or our own billet disc brake hub for easy “slide-on/slide-off” rotor removal.  Buy this hat once and then simply replace only the rotor when needed for cost reducing efficiency.  Makes rotor replacement on the vehicle a snap.  Designed with a common 8 on 7” rotor bolt pattern, this must be used with our racing rotor.  Aluminum finish.  (For standard Ford 5 on 4-1/2” wheel stud pattern.)  7.620" diameter.

Caliper Brackets: These brackets are CNC machined of high quality billet steel to our rigid standards and specifications, to mount our specially machined large four piston calipers.  Made specifically for the big Lincoln style calipers used with our 12” brakes just like the ones made for Ford’s Trans Am program, they're compatible with Ford spindles that utilize the standard 4 bolt mounting pattern found on 1965-73 drum brake and 1965-67 disc brake Mustang spindles.  They come with all the necessary grade 8 mounting hardware and spacers for proper rotor offset and caliper spacing.  Finished in yellow cadmium plating.
