Take the Master Cylinder back. Most likely got a bad one.

You can pre-bleed the master so very little air is introduced into the system.

OK-this morning I pulled the new master cylinder off, checked operation it's ok, bench bled it, bled everything on the car, now the pedal will only go to the floor

after 4 or so pumps. Any thoughts?
