What do I need to do to sort it out? Just been to a cycle maintenance class so I am very well versed in ..... rim brakes.

....but not disc brakes. They look a bit vicious, like they might want to chop my finger off if I do something wrong....

    First we need to identify the type and make of brake please.

    the BB5 have an adjuster for the static pad the red bit on the inside.

    Might help you may need to adjust the cable tension to back off the moving pad. (or reset the caliper.

    the vid should help.

    Tried moving the red bit - it helped a bit but when I backed it off enough to stop it rubbing it didn't brake anymore!
    Can you tell me more about adjusting the cable tension? Do I have to take the cable off and put it back on?

    there is an adjuster on the brake lever where the cable enters.

    well that adjuster near the brake lever was as tight as it could be (it's a very new bike), but I loosened it and tightened it again, the loosened off the red thingy a bit more and now it doesn't rub, and it does stop....

    Three cheers for Nicklouse :D

    Ps I know that thing I did with the tension adjuster did nothing, but it felt like it had the effect of turning it on and back off again - always very therapeutic!

    You deserve a biscuit for that, it's saved you many £s in LBS :lol:
    I've added a signature to prove it is still possible.

    redvee you are not being very helpful......

    But ut's true about the saving - I hate to think how much that would have cost me, and it took a few minutes to sort!

    mmmm! that sounds terminal, you'd better sell the bike now (to me) before it fails completely, I'm just thinking of your well being :mrgreen:
