Hello I have a Opel Combo B built in 1997 with the following problem. And that was when a wheel turned very hard at the rear and the rim got hot when driving for longer. So it was clear brake tight. So wheel down the drum and brake disassembled. New wheel brake cylinders installed and built together. After that the hand brake did not go any more and even the brake itself had hardly any effect. I then made new coverings because by being stuck the lining suffered extremely from it so that it was down to the rivets. But now I still have the problem that the hand brake hardly brakes and also the fus brake does not really have the full effect. You can only notice that when I press the brake the wheel a little hard turns but I can still turn it before hand. Does anyone have a tip what went wrong there? Are the drums so worn off?
