Okay - so my 2004 WRX has had a rattle for some time that I've narrowed down to the brakes. When moving say, below 50mph, every tiny bump there's a rattle with it, above 50ish, no rattle.
So, yes it's the brakes. So what's the fix. I did a search earlier (and today) and recall something about appropriate greasing? ...somehow I couldn't find this today. Or would it be the retention springs? I'd like a little better idea before I dig into this.
