The bleed procedure is Left rear, Right rear, left front, right front, r-abs actuator. ( Did the r-abs get bled?)
Sometimes following thier specific procedure make the difference. Use gradual, slow pressure and return.
It sounds like either the master cylinder tht was replaced may be defective or possibly air is coming back into the system.
I question the master cylinder for a couple reasons. When you lose a pedal and it hits the floor, the master cylinder can be damaged. Thus the replacement. Re-man masters are not always the most reliable ones. You can check the master by plugging the line recepticles after removing the line from it. The pedal should be hard.
I have had bleed problems where air comes back into the line, but doesn't leak fluid out. Why I don't know, but I just know what happens. We were able to narrow it down to the bad line/wheel sector because it did give air.
I would open the bleeders and see if any bubble come out, next check the adjustment of the brake shoes they could be way out.
