Hello, today the annual check was due again. Unfortunately a serious defect was found: the parking brake pulls completely unequal (li 3,00, re 1,40 !). Last year this was still different: there were values at li 3,30 and re 3,50. Since I use the parking brake absolutely NEVER it is obvious that there is somewhere the rope train rusted. Did someone already have the same problem ? Since I would like to fix the problem myself immediately also the question: comes one a n the rope pull just so, or has to there the plastic decoction or the wheels down. Guess that there is nothing without stage, or maybe still ? Normally a little MOS2 spray should pass on the rope pull – or is there a better solution ? Nice greeting
