does one drum get hot after a 30 min drive ?
could be not releasing properly.
i would always do the "check the drum test" after car sitting for a few months

It can be a bunch of different things, from wheel cylinder, master cylinder, main diverter. Self adjusting shoes can be adjusted without taking wheels off, reverse car in straight line then hard on brakes, it adjusts them. Having said that, if brakes are way out of adjustment they can occasionally lock up a wheel, too tight. I've had many master cylinders go, vehicle pull left or right. Wheel cylinders tend to simply blow apart leaking everywhere. Diverter will make you exit stage left or right too. Usually when a wheel cylinder blows, your brakes will spike hard when they are applied, if cylinder is weeping, you already know how bad that is. I would pull each wheel and examine things.
When the drum is off, check to make sure the self adjuster is not seized up. You need to confirm that applying the brakes while backing up is ratcheting the adjuster.
Some great ideas here, you've got work to do!

I've had that happen due to a pinched/blocked brake hose in the past, so that might be another thing to look at.
Sometimes the front brake hoses get weak and balloon out. Also a cause. Check them well as a lot of times they dont get changed unless they are leaking.
Thanks for the replies
I installed new shoes 5000km ago
And double check the adjustment often
I pulled the drum and had my son apply the brakes repeatedly
Seamed like the wheel cylinder was lazy
But with no drum we worked the cylinder in and out a bunch of times
I will test drive and report back
I hope it's that simple
