You have a seized cable.
Likely the cable to at least one wheel.
Look under the truck, driver's side next to the frame. The single cable is likely hanging slack. Yes?
If so then grab one of the cables after the adjuster, where it connects to the rear cables. Give each cable a yank. You should feel springiness, this is the return spring retracting the cable. If you don't feel this, then the cable is seized.
You will have to grab the cable casing about mid way and pull and move it around to work the cable loose enough so the spring can retract the cable. Of course once you apply the parking brake again it will seize again.
The fix is to replace the seized cable.
