Well, I spent about two hours meticulously pulling apart the entire FSVT brake setup, and I've unfortunately still got that slight "ringing" noise. I'm baffled and frustrated now. (Plus, now my sunroof won't work - unrelated I'm sure, but dammit!)

SVTb4, if you have those pics handy or could edit my pics to show me what you were talking about, I'd really appreciate it. I greased up the caliper pins good, and rechecked every bolt (I think).
