That's why nowadays most drum brakes are self-adjustable.

And they're worthless in the wet.

So, unbalanced braking both front to rear plus side to side and worthless in rain.
Not so worthless at all and, nowadays that ABS became more common, braking doesn't get so unbalanced.

Every system has its compromises. Discs may occasionaly bend due to torque, while drums don't have this problem. But anyway, since most of the vehicles still available with drum brakes in my country are either small motorcycles or commercial vehicles fitted with some sort of braking retarder which reduces the load imposed to the brakes, drums are still cost-effective.

We ran disc equipped trailers and tractors in the oilfield. "Rural" doesn't describe where we had to go.
It doesn't really matter if it's a farm, an oilfield, a military operation in the Amazon or the Pantanal, a mining site or a construction, drum brakes are still prefered by many operators in my country.
