Metal on Metal scraping sound when braking
Before you all jump at me saying I have completely worn down brakes and I had to replace them immediately etc. let me first say that I have checked the servicing history and the brakes have been replaced less than 5.000 miles ago, by the previous owner. It was the rear brakes, and that's exactly where I can hear the sound from at low speed braking. The sound is probably there at higher speeds as well but cant hear it.
I just went to Budapest and back with the sound, and the car behaves perfectly normal, and brakes great.
The rotors had a superficial layer of rust when I got the car, but it dissapeared after a day or two.
I checked the brakes, and this is what I see.
The brake pads seem pretty thick and seem to have quite some "meat on them". The rotors are somewhat darker to the outside of the ring, like a dark blue color of some sort.
The scraping sound is not very noticeable, but it can be heard.
(my car is a 2009 r56 non-s)
Thanks to everyone in advance for any helpful tips or ideas.
