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. (Pads are Not included.)
