Your parking brake, is it a yellow "pull for brake/push to release" **** on the dash?

OK to get you going read this thread on the subject. Note there is a link to tools in post 3:

OK I gotta stop here: Are you a good wrench man with brake experience? In my opinion, a medium truck with this kind of braking system is not something to tinker with and try to learn in the field. If you are not comfortable with this, find a shop, or at least run down a factory manual to consult while working on it.
