Originally ICE's braking is accomplished by vacuum generated through the combustion engine. For similar driving characteristics and safety after the engine is removed this vacuum must be supplied by another source.
The VBS vacuum pump replaces the vacuum provided by the internal combustion engine. A switch automatically will turn on the pump when vacuum falls below the set value and turn it off when it reaches it's set pressure. The kit comes with all the components needed for a complete vacuum assist solution. This includes an ultra-quiet pump, automatic shutoff switch, relay, fuse, and tubing.
Most pumps used for vacuum assist produce a noisy drone that diminishes the elegance of quiet electric vehicle operation. |
