Granatelli Motor Sports 12-Volt Electric Brake Vacuum Pump Systems 410101B

12‑Volt Brake Electric Vacuum Pump System

SKU: 410101B

Tired of a mushy brake pedal or unreliable braking after a big cam swap or boosted setup? The Granatelli Motor Sports Brake Booster Vacuum Pump is the fix. If you’ve killed engine vacuum with a lopey cam, added forced induction, or just need more consistent brake assist, this pump keeps your pedal firm and your stopping power solid — every time.

This isn’t your average off-the-shelf unit. Granatelli built this pump to handle real street and strip abuse. It’s plug-and-play, quiet, and pulls a consistent vacuum to keep your brake booster happy even when your engine isn’t. That means more confidence when you’re on the brakes — whether you're launching at the track, carving through canyon roads, or cruising a cammed-out street car.

The pump activates only when the vacuum drops below a set threshold, then shuts off when it reaches optimal pressure — no need to run it full-time. It’s self-regulating, so you don’t have to think about it after install. Just bolt it in, wire it up, and go.

Works great on NA, turbo, or supercharged applications. If your engine doesn’t make a steady vacuum, this is the solution. Especially critical for cars with big cams that idle roughly and make braking unpredictable. You’ll finally be able to stop with confidence — not just hope for the best.

Electric Vacuum Pump Features:

• Supports brake boosters in low-vacuum engines

• Quiet, efficient electric vacuum pump

• Self-regulating on/off cycle based on the vacuum level

• Plug-and-play design for easy installation

• Ideal for big cam, turbo, supercharged, or LS swap cars

Don’t let a weak vacuum hold your car back. Whether it’s a daily, show car, or full-on race build, the Granatelli Brake Booster Electric Vacuum Pump keeps your brakes feeling right — no matter how wild your engine setup is.
