In many cases nothing.
I.e. they don't use Vacuum assisted brakes, they use electrically assisted brakes. Many of the older "production" EVs just used manual (non-assisted) brakes. > What do production EVs use for a vacuum pump?

The half-dozen production EVs in my yard all use a Pierburg diagphram
pump which looks similar to the Gast and Thomas ones that are available from EV part suppliers. It is very reliable. Have a look on this page, the pump used is the black one in the picture: http://tinyurl.com/434zjo On Fri, May 16, 2008 at 12:56 PM, <DOCTORDHD@...> wrote: > What do production EVs use for a vacuum pump?

I guess if you try and run the old heater/AC unit they need vac. to open and
close doors, and maybe brakes if you do not fix it to run with out. On Fri, May 16, 2008 at 6:56 AM, <DOCTORDHD@...> wrote: > What do production EVs use for a vacuum pump?

Hello Evan,
Which one of the Pierburg diagphram pumps make the lease noise when starting out and/or at the maximum vacuum? My GMC belt driven unit that is use on GMC diesel engines, making a clicking noise at start up, but when it gets up to 15 in.hg. it becomes very quite.

Well, it's not production for an EV, but mine was production for
Volkswagons. I have a used mechanical vacuum pump from a VW rabbit. It was cheap and it pretty much silent. For a couple of dollars I picked up a rebuild kit and used a piece of aluminum to mount it to the front of my motor. I'll let you know how it works in the long run.
