Universal Disc Drum Brake Proportioning Valve Kit - PV4 Valve With Lines & Bracket For GM Vehicles

Working on your classic GM ride? This universal disc drum proportioning valve kit is exactly what you need for proper brake balance! The PV4 valve efficiently regulates brake pressure between your front and rear axles, preventing those scary rear wheel lock-ups during hard stops. This complete kit includes the proportioning valve, two pre-bent steel lines with 9/16 and 1/2 inch fittings, a zinc-coated mounting bracket, brake light warning switch, and all necessary hardware. It's a direct replacement for part numbers 172-2187, 172-2174, 172-1364, and several others. The bottom mount design is perfect for tight spaces or frame mounting, making installation straightforward even in confined areas. Compatibility is broad - works with Chevelle (1964-1972), Camaro (1967-1969), Nova (1968-1974), Firebird (1967-1969), GTO (1964-1972), and many other GM classics from the 60s and 70s. The brass construction ensures durability and corrosion resistance, while the OEM-style look maintains that factory appearance. As you apply more brake force, this smart valve automatically reduces pressure to the rear brakes since weight transfers forward, giving you much better control and stopping power. Whether you're upgrading your braking system or replacing a worn-out valve, this kit provides everything you need in one package. The quality matches original equipment, but the price is way more reasonable. Your classic will stop straight and true every time with this properly balanced brake system.
