Our MaxGrip Lite kits are designed for factory drum brake spindles and offer a bolt-on fit for most classic Mustangs and related Ford platforms. For 1967–70 Mustangs, slight firewall modifications may be needed for power booster installation—just like the factory did. Don’t worry—our instructions guide you through every step.

One question we’re often asked is, “How do I install the master cylinder and brake lines on my Mustang?” LEED Brakes makes this process easy with pre-bent brake lines that connect the new master cylinder to your factory distribution block. Start by bench bleeding the master cylinder in a vise off the vehicle. Then, mount it to the firewall, install the new brake lines, and bleed the rest of the system. The power booster mounts using the factory locations, keeping installation straightforward.
