    Vibration in frame

    Well, whenever I brake with my HFX-9's, I use the brake a little bit (pull lever down a little) it hums and vibrates through the frame really loud. Please help I don't know what to do. I tried re alligning them, but if the caliper is straight, it hits the disc. please help. Will it just go away? Thanks for any help.

    It is slightly warped but the vibratrion is consistant it does not happen every rotation of the disc, only when I use the brake a little it does this. Could one of my rotor screws be loose?

    Rotor is warped. Warped rotors can be odd like that.

    My LBS installed it. Maybe I should get them to reinstall them. The rotor only does it when I use the back brake.

    Well first try to push the rotor against a table you know is flat, any surface really. If you see it is clearly true then when tightening do it in a star of david type pattern

    Does it sound like a kind of really annoying loud squeal with lots of vibration? If so, don't worry too much, my front brake does it all the time, it's just a slight warp in the rotor. In a while you will master the art of pissong people off by finding just how much to pull in your lever to make it the loudest most annoying sound and keep it going
