Hello I bought a trailer 10 t from Fliegl Bj 00. When I pulled it 350 km on the highway, everything worked wonderful. Now he stood around for two weeks and I wanted to park him in the yard, now the wheels are turning very hard. Does anyone know what it can be? Now I wanted to put down the brake drum and look what the brakes look like. But unfortunately it is not that easy. The axles are from Austria. I have the wheel hub cover, the crown mutt r and the wheel bearing out, but unfortunately the drum doesn’t go off, does the Simmering have to go down? Unfortunately, Fliegl has no documents for this trailer anymore, so I can’t order a spare handle in advance (like a new Simmering and I don’t want to break it anymore) Do you have any tips?
