This brake booster conversion kit is a game-changer for classic GM builds! Installed it on my '70 Chevelle, and the difference is night and day—smooth, powerful stops with minimal pedal effort. The complete kit includes everything needed for a clean swap to power brakes, with quality components that fit perfectly. The proportioning valve balances braking perfectly between my disc/drum setup. Installation was straightforward following the instructions, and now my ride stops as confidently as it goes. Highly recommended for anyone upgrading their vintage muscle car!
