Check the drum surface, Might need cleaning up good if they got brake fluid or crud on the inner surface.
I would check the shoes to see if they fit the drum inner circumference correctly. They may need arcing.
Also the front shoes are directional so make sure both are in correctly.
I normally do't turn them, just clean super good with something like purple power.
Then sand the braking surface evenly all around the inner surface with paper between approx 100 grit and 220. you want clean metal with no black staining,
I just sand them back and forth in the same direction they turn.
Check for a inner or outer ridge on the inner drum wear surface, might need turning the minimum at a good shop to remove if there is a ridge so they don't grab.
Put together and bleed brakes good all around. Than adjust up so cant turn by hand, then back off a couple clicks.
Then get inside and hit brakes good a couple times to help center them. Than retighten bit by bit till cant turn by hand.
Back off until you can barely turn them and repeat process.
Rarely are the drums warped enough to be a problem, if they are really out of round you will need to turn or new ones. But not likely.
Once you are satisfied they they have been cycled and centered a couple times tighten a click or two until they drag just enough you cant turn by hand.
Hit brakes again and check. might need to go a click or two more?
Or if dragging back off until you hear/feel them barely just rub in one or two spots as you rotate the wheel.
Not scraping or locking up- just barely touching both sides. Do it by feel so both sides are equal.
