Hello. And one more little worry: I observe at my V40 CC Bj. 08/13 more and more that the brake discs in the current season are affected by flying rust already after very short staidness! When I then start the brake lining rubs away quite loudly the rust. At the HA is already about 2mm covering of the disc away. At the front also about 2mm. Short to add: for two weeks rain and no salt, car has just 18.000 km away. What do the coverings look like after 20,000km, covering completely away? ? Thanks for imaginative answers! P.S.: Can bad steel be the cause?????
