Moin, I drive a renault scenic 2 bj 2005 1.6 16v. A few days ago are back right grinding noises. The disc has black soot on the surface. I am now thinking about making the coverings and possibly the discs new, only I am unsure about the electronic locking brake. How do I do it best with the brake. I also don’t have a koöbenrerucker with which I could do it alternatively. Is there anything else I need to take into account. Thanks for the feedback.
