This doesn’t have to be the case. With our Silent Drive Vacuum Pump, you can remove the engine from the equation and use our stand alone pump to provide the vacuum necessary to properly run a vacuum brake booster. The drawback to a vacuum pump has always been the noise. With the use of our OEM quality rotary style motor, noise is a thing of the past.

Fortunately, you don’t need a degree in Rocket Science to diagnose and fix the glitches that are hardening your pedal.
