Rear Disc Brake Conversi on Ford 8in & 9in

The LEED Brakes Rear Disc Brake Conversion Kit for Ford 8-inch and 9-inch differentials brings modern stopping power to classic and vintage Ford platforms. This rear disc brake conversion replaces outdated drum brake systems with a single-piston caliper design paired to 11-inch plain iron rotors, delivering consistent braking response across a wide range of speeds and load conditions. Purpose-built for hot rods, restoration projects, and street-driven classics, this kit addresses the fundamental limitation of legacy drum brakes: fade under sustained use and difficulty modulating brake force on lighter vehicles.

The 11.000-inch plain iron rotors provide adequate thermal mass for street-duty cycles while maintaining simplicity of installation on narrow rear housings. Iron construction with zinc plating protects against corrosion in varying climates, and the single-piston caliper design reduces complexity compared to dual-piston systems, a critical advantage when packaging constraints or budget considerations limit options. The conversion accepts Ford 8-inch and 9-inch rear axles—the most common differentials found in first- and second-generation Mustangs, Fairlanes, and similar A-body platforms from the 1960s and 1970s.

Buyers undertaking a rear disc brake conversion typically own vehicles where drum brakes no longer meet safety or performance requirements. This kit solves that problem without requiring custom fabrication or extensive modification to the rear axle housing. The 60-pound assembly weight reflects the density of iron components and caliper hardware—expect straightforward installation on a lift or in a well-equipped garage.

Whether restoring a collector car to period-correct handling standards or upgrading a street rod for safer daily use, rear disc conversions address a fundamental powertrain need. LEED Brakes has established a presence in the restoration and classic car community for brake system solutions that balance authenticity with practicality.
