Cutting or yanking on it should be the last resort, as you can pull the mounts out too, and have a hanging cable.
Hold out the release while you put the truck in drive/whatever gear, and it should release. I've had to do that a few times, before I finally did the yank trick, and now I have a hanging cable, but the park brakes releases every time!
