drum brake drags after going in reverse ?

[kwmech]

Inside of the drum looking smooth--no lips or ridges? Pull the cup of the wheel cylinder back and see if the cylinder is leaking or maybe only one of the pistons in the cylinder is working or stuck. I was working on a customers 71 3/4 ton last year and got a brand new wheel cylinder from NAPA without the alum puck inside of it. It's like great---now I have to check all these before I install them now.
