Re: Put 'er to work(terrible photos, be better later)

Well I guess you won't have to check your filter then... With it being a "regular" automotive type vacuum booster, I would try the brake pedal to see if it is not returning. Another thing to check the lines to the back of the truck. When you get another tight brake syndrome, start breaking the fittings loose from the front to the back to see where the pressure stops. Also on the pedal getting hard, check the check valve, hose and intake fitting.
