Hello. I wanted to change the drum brakes in our second car. Is it more difficult than I thought. Of course I knew that the things were rusting, but I can’t get the part off. The outer edge is already a gap open, but nothing is moving in the area of the camp. The hand brake is loose and the drum is also smooth. Do I have to solve something in the area of the camp? Before I break something now, I’d rather ask you. It’s as if on the thread on which the 32 screw is turned around to attach the drum is an increase and presses against the bearing. But I don’t see any way to solve anything on the back either. You know advice. Thank you very much. Here’s another picture.
