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

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 the safety, reliability, and performance of a complete power front drum-to-disc brake conversion from LEED Brakes. Designed for classic Chevrolet platforms including Camaro, Chevelle, Nova, and El Camino — as well as Pontiac GTO and LeMans, Oldsmobile Cutlass and 442, and Buick Skylark and GS models — this system delivers modern braking performance with proper hydraulic balance and factory-style fitment.

This GM AFX power front disc brake kit includes black powder-coated single-piston calipers that mount directly to factory control arms. High-performance cross-drilled and slotted zinc-plated rotors help reduce brake fade by evacuating heat and gases during aggressive braking. Improved pad-to-rotor contact results in stronger, more consistent stopping power and improved pedal response.
