Do not use too much pressure trying to pressure bleed the mater cylinder. The resovoir is plastic and the seals are not meant for a lot of pressure in that manner. A better method is to presure bleed from the calipers to the master cylinder but you shouldn't have to do it that way. I still have to believe something is not right with your technique. Another possability is the pushrod from the vacuum booster is way out of adjustment and you are not "compensating" properly when the pedal is released. Disconnect the master cylinder from the booster by removing the 2 nuts leaving the lines connected. Get a screwdriver and push the piston in the master cylinder to bleed the system. Once bled replace the master cylinder back on the booster and try to bleed again. If you can't, you must readjust the pushrod usually by shortening it.
