air brakes wont relese

[Rob Robinson]

Robert my BB has a scheder (sp) valve in the rear of the engine compartment
that lets a tow truck air up the bird in the event I lose air for any
reason. You might try airing up this way to see if it loosens up whatever
stuck valve or something else that is preventing the parking brake from
taking on air and releasing.
