A very common reason to have this problem is that you did not properly bleed the master cylinder. It should be "bench bled". This means you put it in a vise, fill it with brake fluid, use 2 short tubes connected to the outlet ports and bent around into the resovoir, and slowly push on the piston until you stop seeing air bubbles coming out of the tubes. Once you have completly bled the master cylinder, put caps on the outlet ports and install in the car. Now bleed the brake system again and you should get fluid out the front brake calipers. It could also be your bleeding technique. Go to a local auto store and by a "one man brake bleeder". It is a piece of tubing with a one-way check valve so you don't pull air back in while you are bleeding the system. Use a large clear cup with some fluid in it and keep the end of the brake bleeder in the fluid so it can't pull air and you can see the bubbles coming out.
