    Hi

    I got the squeek to stop when i losen the wheel a bit but still i think the brake pads are rubbin becuase the wheel doesny spin freely.

    if anyone knows how to stop this please say thanks

    don't loosen the wheel, you tit. It could fall out :shock:

    Sounds like you have a bent brake disc, there's a thread on this forum somewhere (or you could search parktools) with tips on straightening a bent rotor with an adjustable spanner.

    Ok obv i know that if i losen the wheel it will fall off. I only done it to see if it was overtight.

    No its not bent.

    Then align your caliper.

    If that doesn't work then check that the pads are far enough apart for the rotor to fit easily between them. You might need to re-set the pistons.

    what brakes?

    but basically undo caliper bolts, squeeze and hold lever, carefully tighten bolts so the caliper doesn't move

    if your disc is catching in some parts of the wheel rotation, but not others, then your disc is bent.

    rifu, I've never found the "wuick and dirty" method to work properly, so I always resort to lining them up visually.

    Me neither, never totally happy with rear performance. Tried the strapping lever to handlebars which deffo made a difference, but doing the whole 'loosen caliper bolts, hold brake lever and retighten' never really worked. For some reason it always ended up touching on one side, rubbing, and when you pulled the elvers you could see the disk move. Clearly not good.

    Did a visual alignment (bloody finddly!( this weekend, went for a ride, and has noticably improved things.
