I had same issue.
1st complain:
SA advised this is common for high performance brake (I had 4 M cars past 10 years and never had this issue).
2nd complain:
Replaced rear brake pads and still noise when backing.
3rd complain:
Replaced front brake pads and no noise... for a while.
Then came back after about 2k miles.
4th complain:
Replaced front pads again and no noise so far (500 miles to date).
I really hope noise doesn't come back since it's annoying and embarrassing. But I know EBC is making low dust/high performance pads (red stuff) so as soon as they release, I will prob. replace oem pads to EBC stuff.
