Mine starting a slight squeal while braking when going fairly slow. Not happening every stop - intermittent. Drives me crazy. I'm thinking a brand new car with 6000 miles on it shouldn't do this. I have a 2SS/RS M6..
I did try braking hard (no slide/skid-nothing radical). Still the slight squeal. Haven't taken it in for service as I can't "make" it happen all the time. They would probably just think it's some stupid girl hearing things..
