I would suggest replacing all the copper washers and banjo bolts if you havent already. when i put braided hoses on my bike i used an Easy bleed one man bleeding system. It worked like a charm

Brakes are sometimes better bled in reverse. If you are adding fluid to the master cylinder and pumping it through with the handle or pedal, try doing it in reverse.
Fill your clean oil can with brake fluid and put some plastic hose on it that will fit snug over the bleed nipple. Open the bleed nipple and pump fresh fluid from the bottom up with the oil can. Slow easy strokes, if you aerate the fluid it will form bubbles again in the lines. Capture the excess at the master cylinder but don't re-use it until you have left it overnight for the bubbles to dissipate.

Take the lines off the master cylinder and plug the holes. Then see if you get back pressure. If you keep pumping when you're trying to bleed, and no fluid is coming out anywhere and the level isn't going down, it has to be the master cylinder.

Could be a bad seal in the master cylinder, is the master pushing fluid through the lines.
Try cracking the line off the master, might be airlocked right at the cylinder.

Sounds like the master cylinder or no fluid.
Stupid question but, I take it you are closing the nipple before you relaease the pedal? Otherwise it will just drag air back in and you will achieve nothing.

ISnt there a gasket where you put the brake fluid in? Maybe if that gasket was faulty it would not build pressure.

No one here can tell you exactly what's wrong with your brakes without seeing them first hand!
Try a mechanic!

open the bleed screw and flush it out with compressed air. then follow the basic bleeding guides.
