When I bleed brakes I usually use a Motive Pressure Bleeder.

I've always had an unsatisfactory pedal feel afterward on w123s, so I prefer to put the car on 4 stands and have a helper pump the pedal (using a block to limit travel) while the car is running. This method has always given a proper bleed and a good firm pedal. I believe the w123s need to be bled while using the booster and vacuum.
