GM AFX Power Front Disc Brake Kit Drilled and Slotted Rotors, Black Powder Coated Calipers with 9" Booster Disc/Disc

Upgrade Your 1964–1974 GM AFX with a Power Front Disc Brake Conversion

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, El Camino, and Malibu models, as well as Pontiac GTO and LeMans, Oldsmobile Cutlass and 442, and Buick Skylark and GS platforms, this kit delivers modern braking performance with factory-style fitment.

This system includes black powder-coated single-piston calipers that mount directly to factory control arms. High-performance cross-drilled and slotted zinc-plated rotors reduce brake fade by evacuating heat and gases during aggressive braking, improving pad-to-rotor contact and delivering stronger, more consistent stopping power.
