I'm a newbie to disc brakes. Just got my new bike a month ago. It has the new XT hydraulic discs. I would say I have about 100 off road miles on them. So according to the manual, they aren't broken in yet. Whenever they get the slightest bit wet, they squeel like crazy. Very loud and annoying. I feel some kind of wierd vibrations when they're wet too. Is this normal? will the noise and vibration go away after they're broken in? I sure hope so. A $3,000 bike shouldn't sound like this!
