Any reason why this WOULDNT work?

Apparently this was done by a BMW E36 guy, so a GM cap worked......any idea if it'll work on benzes (more specifically an M119)

I've never used one before so i am not 100% sure as to how the procedure works. I take it you do what ever you need to do to the brakes....like changing calipers or whatever. Then you remove the brake reservoir top, attach the vacuum bleeder. Pump it up to suck out the bubbles then....what? Remove it put back the cap on the reservoir and hit road?

any instructions on how to make one for a benz?
