I'm surprised nobody has mentioned the Speedi-Bleed pressure bleeder (which is NOT the same as Speed Bleeder). Using vacuum to pull fluid through is a bad idea as you almost always get air leakage around the bleeder screw nipples, and the resulting bubbles are a nuisance because you don't know if the lines are clear yet. MB dealers use a pressure bleeder. It works great, although when done you need to remove a little fluid from the reservoir with a turkey baster or something. Make sure you replace the rubber "buttons" on the m/c reservoir before starting or you could end up with a real mess if the old ones are cracked. I love mine, I'm annoyed that I used my MityVac for so many years - the Speedi-Bleed is much superior. You can still get the kit for German cars here for $40:
