Took the mountain goat to the LBS today to have them check my brakes. They were quite busy, but went to the trouble of explaining the process of how disc breaks break in and what has to happen. They also said that I have a light touch on the brakes which makes it much more likely to have noise The wrench couldn't really duplicate what I've noticed. It was very helpful and, most importantly, I know there is nothing wrong with my bike & I am not hurting it. If the noise continues after the breaking in process is complete then we will likely replace the semi-metallic pads with organic, but time will tell. They think they can actually do that under warranty if it is called for.

I love my LBS, they never talk down to me and I always leave understanding more than when I walked in the door.
