GM AFX Power Front Disc Brake Kit 2" Drop Spindle Drilled and Slotted Rotors Black Powder Coated Calipers 8" Dual Chrome Booster Disc/Drum

Upgrade your 1964–1974 GM A, F, and X body vehicle with the safety, reliability, and performance of a complete front drum-to-disc brake conversion from LEED Brakes. Designed for classic Chevrolet, Pontiac, Oldsmobile, and Buick platforms including Camaro, Chevelle, Nova, GTO, Cutlass, Skylark, LeMans, and Monte Carlo models, this system delivers modern braking performance with proper hydraulic balance and factory-style fitment.

This comprehensive GM front disc brake conversion kit includes black powder-coated single-piston calipers that mount directly to factory control arms, along with high-performance cross-drilled, slotted, zinc-plated rotors engineered to reduce brake fade and improve heat dissipation. By evacuating gases that build up between the brake pad and rotor during heavy braking, these rotors increase pad-to-rotor contact and provide consistent, repeatable stopping power.
