Ever had self adjusting brakes overtighten?

I’m going to remove and re-install the brake springs. I’m reluctant to replace the brake shoes before I have reason to think brakes are working okay..... I’d hate to smoke another set of new brake shoes. I’m thinking that the separated piece of liner might drag the drums. Would it be nuts to cut off the loose bit of liner to test the overall brake installation?
get new shoes, but this time get bonded AND riveted, they won't fall apart so easily.
After you replace them, don't go out on the freeway. just drive down around the block and check it. I use my hand to feel the wheels, to tell if one brake is dragging and heating up more than the others.
