Short shoe goes to the front always, they are not interchangeable.

I have seen some people cut drums at high feed on the final cut instead of taking a slow final cut. This in effect makes a thread on the drum surface. When the brakes are applied the shoes move away from the backing plate because of the threaded finish and then the hold down springs snap the shoes back onto the backing plate. It may or may not be the problem, just something I have seen working at a dealership on a brand new car that had a snap when the brakes were applied.

Brake self adjusters on the wrong sides which will adjust the brakes when moving forward instead of only when backing up, or two adjusters with the same side designation, 2 rights or 2 lefts. The adjusters need to be on the correct sides, they are not interchangeable. One has right hand threads and the other has a left hand thread. They are marked with a L or an R stamped on the adjuster.

Frozen/stuck emergency brake cables, quite common on rust belt cars, backing off the cable adjustment will have no effect if the cables are frozen in the cable housings.

Also inspect the brake drums very closely as they have been occasionally been known to crack and make a snapping noise when they get hot, not very common, but it does happen.

With the wheel off the ground transmission in neutral, it should have little if any drag trying to turn it by hand, if it drags trying to turn it by hand the adjustment is too tight, or the emergency brake cables are stuck.
