Proportioning Valve Fitting Kit

The LEED Brakes Proportioning Valve Fitting Kit is an essential hydraulic brake system component designed for custom brake builds and restoration projects where proportioning control is critical. Whether you're upgrading from drum to disc brakes, installing an aftermarket master cylinder, or fine-tuning your vehicle's stopping balance between front and rear axles, this fitting kit provides the connectors and adapters needed to integrate a proportioning valve into your existing brake lines. Proportioning valves regulate hydraulic pressure distribution and prevent rear-wheel lockup, making them invaluable for street rods, restorations, and high-performance applications where factory brake systems have been heavily modified.

The FKPV fitting kit includes all necessary adapters and connectors to mate a proportioning valve to standard SAE brake line ports, eliminating the need to source individual fittings from multiple suppliers. LEED Brakes engineered this kit with precision-machined brass and steel components that resist corrosion and maintain reliable sealing under the extreme pressures generated during hard braking—typically 800 to 1200 PSI in performance applications. The compact design (2.05 x 0.75 x 3.05 inches) fits in tight engine bay configurations, while the lightweight construction (0.11 lbs) adds negligible weight to your brake system.

This fitting kit is ideal for mechanics and enthusiasts rebuilding classic muscle cars, street rods, and modern performance vehicles where OEM proportioning valve systems have been replaced or removed. Installation is straightforward for anyone with basic brake work experience—simply connect the kit's male and female SAE ports to your proportioning valve inlet and outlet ports, then route your front and rear brake lines through the appropriate valve ports. Compatibility spans virtually any vehicle platform using standard SAE metric brake fittings; always verify your proportioning valve model accepts the SAE port configuration before ordering. Proper installation ensures optimal brake balance and prevents rear lockup during emergency stops or track use.
