BoostMaster Universal - Low Profile Flush Mount Vacuum Booster
$475.00
Never suffer from weak brakes or malfunctioning vacuum accessories again. Our BoostMaster Universal Flush Mount Automatic Vacuum Booster delivers the same proven performance as our original under-booster version—now in a flexible design that mounts virtually anywhere.
Whether you’ve got space on the inner fender, firewall, or any flat surface, this compact flush-mount unit provides a clean, professional installation while keeping your vacuum system fully automatic. Pre-set to deliver 23 inHg (inches of mercury) at sea level, it activates only when needed, maintaining a consistent vacuum source without constant pump operation or excess wear.
Perfect for brake boosters, pop-up headlights, HVAC doors, and other vacuum-powered systems. For best results, feed engine vacuum into the booster as a primary source, allowing the pump to supplement only when necessary—maximizing longevity and performance.

FREQUENTLY ASKED QUESTIONS
Do I need power brakes and an existing brake booster for this to work?
Yes. The BoostMaster is designed to work in conjunction with your vehicle’s existing power brake booster. It mounts directly beneath it and enhances the vacuum supply when engine vacuum alone isn't enough.
Will it fit my car?
The BoostMaster is engineered for universal fitment for most GM classic cars. However, some minor modifications may be required depending on your specific vehicle layout or brake booster configuration. Its compact design makes it easy to integrate without cluttering your engine bay. Check the dimensions in the product images to see if it will work for your setup.
Why would I need this?
If your classic car suffers from weak brakes, slow pop-up headlights, inconsistent HVAC doors, or any other vacuum-related issues, the BoostMaster is your solution. High-performance engines with big cams, superchargers, or modified setups often don’t produce enough vacuum for accessories to function properly. The BoostMaster ensures a reliable and consistent vacuum source, giving you safer braking and fully functioning vacuum-powered systems—automatically.
What if I have a vacuum leak—will this solve it?
No. The BoostMaster is not designed to fix vacuum leaks. If a leak is present, the pump will detect the low vacuum and run constantly, leading to premature wear and reduced performance. It's important to repair any vacuum leaks before installing the BoostMaster for best results.
