I've also noticed the buzzing when breaking. I've not really found it strange.... It sounds like an electric motor spinning down to me, which is something that I would almost expect. Wither it's the AC or IMA I don't know, but I figured it was one or the other.

But of course, since I don't know, I could not say wither the buzzing is good, bad or indifferent.
