I think you know that. If pulling and releasing won't make the parking brake work again, you need to have it looked at. The official method of replacing the caliper is to advance the pin on it so it just touches the piston after install so you won't have a loose hand brake. I am lazy. So I use the pull and release, or time will make it work again method.
