These trucks automatically adjusts the rear brakes for even braking and parking brake pressure.
But the passenger-side grabs more, to the point of heating up and locking the drum and the whole rear while driving!!!

yet, every time, to unlock the drum; I apply- and release the parking brake and the wheel spins free.
I remove the tire and drum but cant find a problem...

WHATS HAPPENING!!!!!!!? im afraid to drive....
