Ya, it's truly stuck. I believe the computer freaked out. The only thing I undid/removed was the ABS sensor that goes into the front axel/rotor/caliper area. Simple plastic "floating" sensor that comes out very easily and back in very easily. IDK. The weird thing is, using an ODBLink and FORScan in Dashboard mode, I can see the computer reporting the parking brake going on and off with the switch, yet the back brakes are locked. Anyway - I took it to a nearby dealer that I trust so we'll see what happens. Also, when I dropped it off I noticed in the Ford App the TPMS system wasn't monitoring anymore either. I believe it's all a computer/software issue.If it truly stuck you could unbolt the actuator, back it all the way out, reinstall and see what it does.
