Yeah, I'm pretty sure contaminated brake fluid caused it though. It's funny, 'cause I just realized awhile ago I asked about a smell that was coming from my Xfire, thought it was burning clutch, someone told me it was the brakes. Now I know why.
Oddly enough, the brake wear indicator still hasn't come on. 
I don't know if it's just me noticing it more now, I do listen for it intently now, but it seems to be much more noticeable. I'm figuring I need the caliper rebuilt and at least the rotor put on a lathe.
Does anyone know how tough our rotors are?
