Hello, since June 19 have a Karoq TSI with 150 hp, automatic, 4800 km. Unfortunately, I have been annoyed for a long time: When driving backwards, one or both rear brakes “ratter or swing” and make a hell of a noise. I have the assumption that this can be due to loose brake pads or not completely loosening brake. When driving forward, this problem is not present. Maybe someone can help me in the forum? Thank you for the answers.
