OK knowing that the peddle is going all the way down tells me everything. Your master is new so regardless of how many time s you have bled them you still have air present in your lines. I am goimg to give you special instructuins for doing what is called a 'gravity bleed'
take off the resivior cap (make sure its full of course)
Starting with the wheel furthest from the master open the bleeder and let it drip. Do not touch the peddle AT ALL. Be patient and just watch it drip. When you have lost about 25 % of the fluid from the resivior close the bleeder and go to the next wheel and repeat. Gravity will do all the work, you just have to be patient and keep the resivior full. You should accasionaly see a bouble or 2 come out of the bleeder. Lightly tapping the calipor to vibrate it will also help the air escape. You do not want to use the 'pumping' method any more, it obviously for some reason isnt working and you could at this point mess up your new master's seals. Afterr bleading all 4, put the cap back on and without starting the vehicle, gingerly pump up the brake pedal. It should build up to a point of not going down anymore, if anything it should atleast improved a lot. If it doent then for whatever reason you master is no good. I have seen bad ones come strait out of the box so its not impossible. Just be sure to be patient when bleeding cause you want thre entire length of brake line to have a chance to dripout. I know this will help, pumping the system creates to many possibilities for air to get back into the system. A gravity bleed is garunteed to reduce the wear & tear and is easier to monitor.
