Brake Disks problem?

Joshuashaw

I own a Kona Stinky Deluxe '06 and recently when I'm going fast on it, the brakes disks by the sound of it seem to be making some noise like there dry and grinding but not a bad grinding noise, like a metally sound. I intend to get new brakes pad for riding this summer, but does anyone know the cause of this sound thanks? Joshh

Something round here tastes bad. Could be plain old bad taste.

I get that too sometimes with my hfx-9 v8s. I think it is just that the rotor is a bit bent and is rubbing. normally it sorts itself out pretty quick after a half day of proper riding.

If the rotor is bent or there are imperfections in the pads and its causing the set-up to vibrate then as the speed of the wheels increases the noise created will sound like a whining. Spin the wheel slowly and listen for a graunching sound which may indicate a damaged rotor, alternatively take the pads out check to see if they are cracked or worn. Might also be worth checikng the rotor fixings are correctly torqued-up. If the rotor is slightly loose then it will vibrate as you go faster.
