Well I had a similar thing happen - but it wasn't brake related. I raced a guy with my 2001 GT1, and afterwords I noticed this weird rubbing / grinding sound coming from front passenger side, and it was louder when I slowed down. However, I turned my car off and back on, and it went away. I had infact partially thrown my serpentine belt, and when I reset the car, the tensioner re-tightened and pulled the belt back into the proper position. You may way to check your belt, it could possibly be off far enough that it can't fix itself, but not far off enough to be thrown yet. Just a possiblity.
