Brake resevoir empty

Truck sitting for a few years, the resevoir was empty and I filled it up, but no brakes. Pumped it a number of times, resevoir not emptying but no brakes. I am leaning towards master cylinder. How would I know for sure.

Re: Brake resevoir empty

Have someone pump the brakes a few times and hold the pedal down. Then crack the lines at the master cylinder one at a time, pumping the pedal after each open and don't let the pedal up until you reclose the line.
