My two cents worth...
On my tagalong trailer brakes, my number one issue with dragging brakes is the inner camshaft bushing. Looking much like a tennis ball, it is held in place by a left and right cover plate. Corrosion effectively squeezes that bushing until no amount of grease can allow smooth action. That includes rust scale inside the covers, and the bore of the axle bracket.
Anytime I have doubts, I fully assemble the camshaft without shoes in place, and ensure that I can 360° rotate the cam EASILY.
