1966 - 1972 Chevelle & Nova Hydraulic Brake Assist Hydro-Boost, Black Aluminum Master Cylinder, Combination Valve Kit, Disc / Disc
Upgrade your braking performance with our complete Firewall Hydro-Boost Power Brake Conversion Kit with BLACK master cylinders and proportioning valve. This kit is designed specifically for 1966 - 1972 Chevelle and 1968 - 1972 Nova with 4-wheel disc brakes. This kit replaces your bulky vacuum-assisted booster with a compact, high-performance hydraulic setup that delivers up to 1800 PSI of brake line pressure — perfect for vehicles with limited vacuum or tight engine bays.Powered by your vehicle’s power steering pump, the Hydro-Boost system dramatically improves stopping power and pedal feel. It’s the ideal solution for cars running big cams, aftermarket intakes, or just needing extra clearance. The unit provides the firewall and valve cover clearance of a 7” vacuum booster while outperforming larger vacuum systems.
Designed for easy installation using common hand tools and average mechanical skill, this kit is perfect whether you're upgrading from manual brakes or replacing an underperforming vacuum booster.
Get modern brake performance, painted black, more engine bay space, and a cleaner install—all at a great price!
