Mustang II & Pinto Disc Brake Conversion Kits
ECI introduced the first Mustang II/Pinto "BIG BRAKE" conversion kit in 1981 and we still offer the largest selection and the best value in the industry. Our 11" diameter rotor kits use the early GM "BIG" piston calipers and provide 65% more braking capacity than the stock Mustang II, and more than twice as much as other so called "Big Brake Kits" using the later smaller piston GM calipers.
Our selection of Mustang II/Pinto conversion kits are available with 4-1/2" Ford and 4-3/4" GM bolt circles and as Basic Kits or Complete Kits.
Basic kits - include caliper mounting brackets, hardware and inner bearing adapters (as required)
Complete kits - include the basic kit components plus new rotors, new calipers with semi-metallic pads and mounting bolts, new inner and outer bearings and seals
