Hello together, I was at the dealer’s store a week ago because I needed new brake blocks. When changing the blocks, the master also changed the front brake discs directly because there were “points” on the right brake disc. He said it had been overloaded and therefore it would have become too hot. I insisted, of course, that the discs be changed on guarantee, since it is not possible to brake strongly without the brake discs Well, the dealer sent the windows to BMW and yesterday I got the answer that it’s not a guarantee case. Do you know where I can now have a material test done? The whole thing happened to me only to a disc. Or did you happen to do that? Greetings bmwlieber007
