    vibrating disc / brake help

    Hi all.
    I am new here so hellooo.

    Ive had a Boardman pro MTB for some time now.when I am going dead slow or walking along with said bike the back pads must be dragging as there is a squeeling noise almost a high pitch vibration through the frame. I have removed the wheel and lightly sannded the disc and pads twice but it still does it. Highly annoying.it has avid elixir r brakes.
    Any thoughts or advice gratefully taken!!

    back off the pads inward and outward, loosen caliper bolts then squeeze brake lever until both pads are touching disc then while holding lever tight tighten the caliper bolts. This should center the rotor in the caliper. Then adjust the pads. If still rubbing maybe your rotor is slightly bent - they are pretty easy to bend back if you take your time and do a little bit at a time. Clean your rotors if you've touched them as they will be noisy otherwise...just some ideas that have worked for me in the past

    What did you sand the disc and pads with?

    If the noise only happens while "going dead slow or walking along with the said bike" it's probably not worth worrying about.

    If you ride faster and don't use your brakes while walking the bike you won't hear this noise.
