Add the safety, reliability, and performance of modern front disc brakes to your 1964–1974 GM A-Body, 1967–1969 F-Body, or 1968–1974 X-Body vehicle with this complete drum-to-disc brake conversion kit from LEED Brakes. This kit includes everything needed to mount black powder-coated single-piston disc brakes directly to your factory control arms.
All components in this black powder-coated caliper brake kit are new, high-quality, and precision-machined for durability and consistent braking performance. The included high-performance cross-drilled, slotted, and zinc-plated rotors help reduce brake fade by venting gases that build up between the brake pad and rotor during heavy braking. This improves pad-to-rotor contact and increases overall stopping power. And yes—the black powder-coated calipers look just as good as they perform.
All LEED Brakes booster and master cylinder assemblies are preset before shipping. Watch this short video to learn how to properly measure pushrod depth and verify your measuring tool for accuracy to prevent brake drag.
