The CPP Complete Power Brake Booster Kit (Part Number 6474BB24-8D) includes an 8" dual gold plated booster with master cylinder and proportioning valve combo. Compatible with 64-72 A-Body, 67-69 F-Body, and 68-74 X-Body models. Suitable for both 2 and 4 wheel disc systems.
Many classic vehicles, including Tri-Five Chevys and pre-1967 cars and trucks, came equipped with single-reservoir master cylinders. While these served well for decades, a failure in any brake hose, wheel cylinder, or line could evacuate the entire system, compromising safety. Upgrading to a dual-reservoir, power-brake setup not only adds redundancy but also reduces pedal effort—an especially welcome change for weekend cruisers and street rods alike.
