Thumbs down W126 - Brake Flush = Dragging Calipers?!

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?

So should I do as I thought and start from the top at the Master Cylinder and go down the line?

Thanks for the quick reply, I really appreciate it!

just keep the MC full and have someone pump and then hold pressure to the brake pedal. You ....at the same time as pressing pedal... go and open the bleeder for 2 sec.
repeat until no more air is pushing out.... just fluid.
should be fine after
