Brake noise, warped disc?

[adw]

Hi guys,

I had my bike on the paddock stand yesterday oiling the chain and when i was spinning the back wheel i noticed that there was a rubbing noise coming from the rear brake at the same Point every time the wheel got turned. The noise goes away once you've turned through that point so is not a consistent rubbing. (Make sense??)

Is this normal? The bike is new with 2k Miles now. And the wheel was removed and put back on recently for a puncture repair.

Could allightment issues be causing this?

I used to hear that with mine, this was before a 500 quid service, I'm not been any help here am i? :rolleyes:

I'll get my coat

if it was alignment it would most likely be rubbing all the time. if it is intermitant (at one point only) then it could be a bent disc. like when you get a buckled wheel on a push bike and the rim rubs against the v-brakes (asuming your still in the middle ages and not using disc). take the rotor of and put it on a flat surface, you should be able to see if it is warped. if the shop fixed the puncture for you there could be a chance they dropped the wheel and the disc got clipped. go back and complain if it is.

Quite worried then because I can't prove the shop did it because it might of been happening before.

It couldn't be anything else?

Is it actually affecting your braking or the performance? If not I wouldn't worry about it. There is a bit of runout allowed on discs anyway.

Will your dealer know that the wheel has been removed, if not take it to them and say "I just noticed this [grinding] noise whilst cleaning, can you check it out for me" you may get it fixed under warantee.

Yeah sounds a good idea. But i wouldn't call it a grinding noise, more a slight rub as the wheel passes a certain point. If i spin the wheel by hand then it will spin for quite a while so the rub can only be slight.
