Break rubbing rim

I just noticed that my back break is rubbing the rim at one side. It isn't always rubbing the rim though. I turned my bike upside down and span the wheel, and it only rubs against the rim at certain points. Does that mean my wheel is off center? How can I sort this problem?

Thanks in advance. :D

    Sounds like your wheel needs truing.

    Do you think the wheel could be buckled ? It would seem to be the obvious answer. The wheel should be able to be trued, if you can't do this your LBS should be able to for about five quid.

    Yes - there are some good web tutorials on how to true a wheel - it isn't that hard but you need to buy a spoke key first. Otherwise it's a very cheap job for a bike shop to fix it for you.
    it's a hard life if you don't weaken.

    If this were to happen whilst out riding, with Shimano, it's poss. to progressively open up the quick release lever i.e. You can open it a bit, but don't need to open it all the way out - Obviously, check you can still apply the brake with enough force before the lever hits the bars!
    With Campag. you throw the q/r pin on the lever, and it should widen the caliper too.
    The advantage to the Campag. q/r is that you can actuate it whilst riding, and you're at no higher risk of the lever touching the bars.

    If they're dual pivots, if you grab both sides (i.e. both arms), and twist, they you can usually realign them.

    Here's a vid on adjusting the V-Brake till you get to the shop.

    The screws that he is showing you can be taken out and replaced with hex head screws, which are a harder comp and easier to use than Phillips screws. Your bike shop can deal with it with you. They will be around 2 millimeters in wrench size.

    Have you checked that you haven't got a broken spoke? It may not be immediately obvious.

    I checked the spokes and they all seem fine. I'll see what the bike shop has to say when I have time to pop in by. :)


    *Edit* Oooh I think I fixed it :D
