Either your caliper is bad or the rubber brake line is bad. Have you checked either? If not, do this.
Securely lift the front of the vehicle remove the tire where the problem is. Press the brakes so the caliper sticks on. Then release pressure from the bleeder. If the caliper repleases, chances are the rubber hose is bad and only allowing pressure to travel one direction. If it still doesn't release, either the caliper piston is sticking or the pins are corroded and not allowing the caliper to release.
Let me know what you find.
