It's basically an oil extractor. Commonly used by BMW mechanics to do their oil changes. Bmws don't have an oilpan drain so they can charge their customers ridiculous money for a simple oil change. I use it to change the oil in my 4runner it's just cleaner and simpler. Don't have to take the skidplate off to prevent oil from getting everywhere.
This is an instance where i think it can be used. I havent used it for bleeding the brakes before. Just hoping to use it to extract the brake fluid from the bleeders. Hoping somebody may have some insight on whether the vacuum will cause any damage to the braking system.

There are plenty of puprose-built vacuum brake bleeders out there. The real question is can you regulate the suction down low enough so that you can keep the reservoir from sucking air while drawing fluid from the bleeder. If you can do that, I don't see how it could hurt the system. If I have my fluid dynamics right, the system won't 'feel' the vacuum in the extractor--what matters is the volume per unit time that passes through the bleeder.
I use a compressor DIY set-up that cost $4 plus some stuff I had lying around. If the extractor does not work, do a search on 'one-man brake bleeder' on this forum and I'm sure you'll find it. Might even have a pic of mine.
My old e23 (1985 735i) had a drain plug--when did they come up with that idea?

Thanks. I think I can make it work. I just have the extractor and it's so handy or am I just lazy? Lol!
I'll look for the one-man bleeder before I put the extractor to the bleeders. Have found some posts on it but haven't seen any with pics of the device. I'll search again. Thanks again.

Not sure when they started it but my sister in laws cuz has a BMW and we were chatting. He was complaining of his $300 oil change I couldn't believe it. He is a lawyer he can afford it but still. I asked him to research how to change the oil on the net and when he found I'd give him a hand. He's now not getting raped by his dealer and he ended up buying an extra extractor for me as well
