Electric Vacuum Pump

I used one on the Charger I had. It worked ok, but felt it didnt have enough "volume" for the pedal to feel right. I had a canister I was going to add to see if that helped add any volume to the system but sold car before I got around to it. Pump will only work to hold vacuum, or when the brakes need more vacuum so its not constantly on. But they are sorta noisy when they do- sounds just like a 12v air compressor if you've ever used those for your tires.

I dont recall the brand, but it was one of the main brands you see if you search google.
