Hello, I have here an Opel Ascona C, 1987, 1,6i Kat, 75 HP. 4-door. My problem is now the handbrake. In 1 month I have to go to the TÜV and it can be pulled up to the 5/6 rest. That means it should be repositioned. The rope is extremely loose below. The two wheels with the drum brake still brake evenly when I pull down on the rope. Well, however, it can not be easily adjusted, since the nut is rusted on the thread rod. Spraying with Mo was so far erf Could anyone help me here or give me some good advice?
