I had a similar problem. It began after a front disc brake conversion (with new master cylinder) on my '68 Camaro. The brakes worked great when cool, but as the car got up to normal operating temperature, the brakes would not release all the way and would drag. It was like they were partially applied all of the time. I was able to cure the problem by shimming the master cylinder out about 1/8 of an inch from the booster (edit). As a quick test to see if this might be your problem, after you notice the problem stop the car and loosen the master cylinder mounting bolts. If the brakes release when you do that, you probably need to shim the master cylinder out or shorten the pushrod slightly.
