Hello, I need a little help. I have a 626 GF Bj. 2001 100 KW. Since recently I have the problem that the rear left brake is “fixed” and the wheel gets very warm. First I changed the windows and coverings behind (due anyway) and made the saddles workable again (brake saddle – brake caliper holder) and lubricated. Then the problem was gone, unfortunately only about 2 weeks. Today the left rear wheel was very warm again. So stillma l Wheel down and checked. Now I noticed that after releasing the hand brake I can pull back the small lever on the saddle about 1 cm. If I put out the train, the lever goes back completely by itself. I’m not quite sure now – hand brake rope rusted, lame spring on the saddle or defective saddle (resetting mechanism). The brake rope can be moved with the hand in suspended condition relatively easily, but only in a relaxed direction. what I should exchange first. Thank you very much in advance. Mfg nofear4212
