All LEED Brakes kits for the 1964–74 Mopar B Body are engineered for a hassle-free install. Our disc brake conversion kits are designed to bolt directly to your factory drum brake spindles, eliminating the need to re-align your suspension after installation. Stopping power is delivered by 4 piston calipers modeled after the original Kelsey Hayes units used on early factory disc brake Mopars. These calipers include stainless steel pistons and are zinc-plated for optimal durability.

Wondering how to connect brake lines to the new master cylinder? LEED Brakes makes it simple. Each kit includes pre-bent lines that install directly from the new master cylinder to your factory distribution block. Just bench bleed your master cylinder, mount it to the firewall, install your new lines, and bleed the system. The power booster installs into the factory firewall mounting points. Factory power brake cars may require minor firewall plate modifications, which are fully outlined in the included instructions.
