Hi Everyone,
My front breaks are unbearably squeaky noisy. I took the car to Santa Monica BMW who refused to do anything, saying they are functioning fine. (Never going back to that awful dealer.) Then I went to BMW of Beverly Hills, who a least acknowledged the problem and performed a complimentary chamfer (which is some sort of filing of the pads) which seemed to helped for a few days but now it's back and very loud. They are not going to do more.

Anyone else have this issue and how did you solve it?
And if you are going to recommend aftermarket pads, please tell me which you chose and why.
Thanks!

My car is a 2011 135i cp.
