Hello, I bought new brake discs for my smart here:www.at-rs.de/beitrag/items/brake disks_rost_corrosion.html I have bought these with the paint of the brake pots knowingly, in order to be perhaps a little prepared against rust. Today the discs, which are to be installed tomorrow, were delivered. What is very surprising to me is that the discs were completely painted against the picture under the above link. So also the inner surface of the pot and also the friction surfaces. On the friction surfaces it will certainly be braked off after a few times, which is also in order. But what causes me a little stomach pain, that the inner surface of the pots was painted too. Although the paint layer is really very thin there, but whether that is so ok? Are brake pots not always totally blank inside? Would I be happy about a few opinions.
