Hello, if I am not in Berlin for 6 weeks, my Polo GTI only stands around. In the process strong rust formed on the brake discs, which is then driven into the pads. My Astra stood against it twice 8 weeks, there formed only flight rust, which was after 20km. I now have to replace discs and coverings at the polo. Since the problem is obviously also on the brake disc material, I would like to do without original parts. There are (additionally perforated) discs of Zimmermann, has jema nd experiences with it? Or does someone have a solution to reduce the rust attack (except “drive more”? Thanks in advance! rumey
