400 miles after new brakes, and they look like this

bhimpele · 06-19-2018, 08:19 AM

I had new brakes put on my 2015 M3 about a month ago, and on the rear passenger side, the outer rim of the rotor looks like this. It's still flat, and there is no depth to these 'scratches', but it is still alarming to me. Any thoughts?

Looks like the factory cross hatching was a bit deeper around that edge. Don't worry about it, it will go away after more miles.

If it's still around during your 1200 mile break-in service, I'd bring it up with your SA. Otherwise, it should slowly dissipate during the bedding-in process.

Give it another thousands miles. It should go away.

I am assuming a 2015 M3 has had its break-in service already
