If you have one of those problem brake systems that you just can't get bled properly, try this......
After you have bled the calipers good, turn the bars all the way left, then tie your brake lever in the "squeezed" position with a bungee or the like, fill the master cylinder and go to bed. In the morning before you release the lever, tap around the outside of the cylinder and line with a hammer handle and watch inside the cylinder at the bubbles that come up in the fluid , test your brakes and make sure all is OK then go ride!

And also Here's some info on bleeding the brakes and hydrallics on most vehicles... HERE
