Sticking (dragging) left front brake (9" drum)

Yes what wjajr said for sure, and if it is dragging the brake it is getting hot,thus no brake compared to the right cool brake :sad4:
I had a break line on my dodge truck do what wjajr is talking about, if I hit the brakes then drove away the brake hose swelled up and would keep pressure on my disk brakes, I am sure this is true with drums also
