TMaster 12V Brake Booster Vacuum Pump kit - "Plug and Play" w/installation kit,Quiet high-performance 18'' to 25'' electric vacuum pump for brake booster

It’s so simple to install and works great ! I now have stopping power!

Improved braking performance on a 1965 model vehicle significantly by reduction in peddle pressure

it works great

UPDATE: After a year of use on my 57 Chevy show car this pump is still going strong. Just fired up the car after a long winter and the brakes worked great. I highly recommend, and I just bought another one for my 68 Camaro with a big cam. Worked great out of the box. Tested it and found this fixed the issue I was having with my low vacuum at idle 327/365 Corvette engine. The power booster wasn’t working properly. Vacuum needs to be above 18” of mercury at idle. This improved my stopping power by 50% and reduced my stopping distance by 1/3rd. Excellent stainless steel bracket and hardware. Mine came with no instructions as the box was opened, but it’s east to put together and mount. No issues so far.

Got this to replace the mechanical vaccumm pump on my diesel truck. The mechanical ones are only lasting about 40,000 miles. This pump was super easy to install and works great. I did use a 1/16 inch thick piece of rubber betweent he pump and the fender I mounted it on. Very quiet. Like an electric fuel pump. I can barely hear it with the engine off. It draws down quick to 24 on my gauge. I will update with milage when I have to replace it. Sooo much easier than replacing the mechanical pump. Update: Almost a year into it and still worked GREAT! UPDATE: got a second pump. Vacuum switch went out after about 2 months. Seller sent one and I also got a spare here: https://www.amazon.com/dp/B0BXLW7YLR
