Chrome 9" Dual Power Brake Conversion Kit Disc/ Disc Chevelle/ El Camino 64-72 Bottom Mount Prop Valve

This kit installs cleanly at your 1964-1972 Chevelle or El Camino's factory firewall location, providing the adjustability and stopping power expected from a modern performance braking system. It combines a chrome 9" power brake booster and polished aluminum master cylinder that bring a custom look to the engine bay. The large 1.125" bore master cylinder increases fluid volume for applications that demand stronger hydraulic performance and consistent pedal response. Plus, an adjustable bottom-mount disc/disc proportioning valve allows precise brake bias tuning, allowing you to balance front-to-rear pressure for aggressive street driving or performance builds.
