Lousy brakes

Sounds like the master still has air in it. Edit: what kind of brake fluid are you using? Brakes are hydraulic so you should not need to pump them up unless there is air. I once had a defective brand new master. Poured two large bottles thru the system and still could not get it bled. Not saying that is your problem. Do you have someone helping you do the MC bleed? How are you bleeding the MC? I use the OE style metal tubes style and I cut the tubes and put plastic tubing over them and down into the fluid. I can then see bubbles and slowly push the brake pedal back and forth until all the air is out. You need to push the pedal all the way down with long, slow strokes. Only after ensuring no air is in there should you reconnect the lines and bleed at each wheel. If you're using an iron MC, it has compensating ports in the bottom. If you slowly pump the pedal and see silver in the port that means there is still air trapped.
