I'm only guessing, but I'd say that there is a problem with the fluid return to the master. There are several reasons for this, and for a more accurate diagnosis, it would be good to know why the brakes were bled. New parts? Which ones?
Any way, the two reasons for this that i can think of off the top of my head are:
1. Brake pedal/ rod out of adjustment. in other words, the brake piston in the master cylinder is not being returned to its normal position. This means the return ports are not getting uncovered, so the brakes will be stuck on.
2. Dirt clogging the return port, this to me would on ly be likely if an old master was used, or the brake system had been empty for a while, so rust could form.
3. Okay, I just thought of a number 3, perhaps, if you have power brakes, the vacuum diaphram check valve might not work so well, this is usually indicated by the pedal staying dowwn.
4. Oops, they keep coming. If there was a stuck caliper this could do it.
5. Forget counting. If its in the rear brakes, and you had it disassembled, the brake adjuster could be in backwards, and any sort of forward motion is going to cause the brakes to over tighten. This happened to me once. It was very difficult to remove the brake drum because my brakes were so over adjusted.
Like I said, more info would make a diagnosis easier.
