Recently purchased a new (to me) bike w/ Hayes 9 brakes on it. This is my first set of disc brakes. I noticed that the front brake buzzes after it gets a bit of heat in it, like 3 min down a fire road w/ grade < 10%. This noise is not a squeel its a buzz. There is no loss of power nor does the brake lever get soft, so I don't think its a bleed issue. The buzzing noise doesn't happen to the rear brake, so its not a brake system issue. Plus, when the bike is in the stand, I can't recreate it. The pads are new and broken in. Any ideas on what I can do to stop the buzzing?
