Opening the bleeder valve to release the pressure is an indication that the Master Cylinder is clogged..there is a tiny return orifice in the MC that collects gunk and once plugged will not return pressure to the MC thereby relaeasing the brakes..
At the least you will need to remove it and CLEAN it - perhaps a rebuild is in order with new rubber bits as well...check the hoses at this time as a collapsed hose may show similar symptoms.
Adding Steel braided brake lines will eliminate this problem and deliver better braking.

Most likely the blocked orifice is the cause of this problem. See steps 8 and 8a in How to rebuild your front master cylinder - it can sometimes be easily fixed, without removing the master cylinder.
