Okay last night I flushed the brakes on my 300SD and I've flushed brakes many times before on Domestic vehicles, the only thing I can think of that could be a problem is that during this process I failed to notify the person watching the master cylinder that there are two chambers within the reservoir.

So the MS went dry on the front circuit...
So, do I need to bleed the master cylinder then go back and bleed each wheel again?
I was going to go cruise today... but not until I get this resolved.

Thanks for any help guys!
