Upgrade Your 1964–1974 GM AFX with a Power Front Disc Brake Conversion (Disc/Drum) Upgrade your 1964–1974 GM A, F, and X body vehicle with a complete power front drum-to-disc brake conversion from LEED Brakes. Designed for classic Chevrolet Camaro, Chevelle, Nova, and El Camino models, as well as Pontiac GTO and LeMans, Oldsmobile Cutlass and 442, and Buick Skylark and GS platforms, this kit delivers modern stopping power with factory-style fitment. This Disc/Drum configuration includes 11-inch cross-drilled and slotted zinc-plated rotors, red powder-coated single-piston calipers, a 9-inch power brake booster, and a matching master cylinder. The drilled and slotted rotor design reduces brake fade by evacuating heat and gases during aggressive braking, improving pad-to-rotor contact and delivering stronger, more consistent stopping performance.
