Now, what was the reason for the movement?
Not shure, but clear: Not the German dealer.
I think, in September last year we’ve done a nice journey in the Alps. Stelvio, Umbrail and some more. At the end the MOGs rearbrake screams sometimes. So in the cars hibernation I undo the rear wheels and the brakedrums for a cleaning.
It looks that the right side was fitted correct and at the left there was something wrong. In cause the most time this year I‘ve had problems with my left leg and can‘t operate the clutch we‘ve done only 200 KM. So the problem wasn‘t noticed. At MOT I told the engineer „please don‘t use the braketesting machine“. He agreed. And drives the car for some tests. One was stopping the car from low speed with the handbrake. Another point rolling/driving backwards the same. An unusual drivingsituation. I think in this test the wrong fitted brakedrum and the wheel settles correct. And than by the following control the movement was visible.
But now it‘s cured and a testdrive the next nice day will show what happens.
