Moin moin, I installed AC Delco Brem disks last summer, as the old brakes fluttered while braking. Now I have the same problem after 10,000 km and have set EBC disks installed. But also these run not 100% round but rub easily. Could there be other vulnerabilities for this problem? If I have to brake sharply now from 150 km/h, I also feel a vibrating in the brake pedal. Maybe I’m too pedantic, but somehow it’s annoying after all. Greetings Frank
