Understood.
I suggest you load a heavy trailer and do a full-on emergency stop from above 65-mph. Brand new brakes.
Ruptured seals, missing linings, etc.
From sixty they'll make it. From above 65 it's not worth the chance.
Point being that now it's up to the tow vehicle to do the work. The trailer brakes have essentially failed.
Disc doesn't have this problem. They're also not out of adjustment before leaving the shop. Drums can grab and pull to one side, or one Axle of two or three does all the work.
Drums are just barely acceptable.
The test is using trailer brakes only to stop the rig from 30-mph.
