Brake rubbing rim

Catrin2010-12-12 18:44:28 +0000 #1
Just noticed that one side of my rear brake is making full contact on the rim - is there a way that I can fix this? I am willing to try, though can take it to my LBS if needed - I am hoping this is a quick fix....

Ideas on how to proceed would be greatly appreciated!

The brakes are cantis.

Never mind - after doing some reading about how to do this - I am going to swing by my LBS. It looks like there several things there that I don't yet understand and I don't want to mess up my brakes....

Do you mean one side of the brake is "on" even when you are not squeezing the lever?

See the straddle cable that runs from one canti to the other? There is a curved guide/clip/thingummy on the end of the brake cable that should be centered on that straddle cable. If it got nudged off center, one canti will be pulled toward the rim even when the tension is off the lever. No biggie. Happens all the time. Either squeeze the brake lever real hard to center it, or nudge it back with your fingers.

Don't do this while moving, obviously.

Yes, one side seemed closed on the rim. I released cantilevers in rear and rear wheel quick release. Made sure wheel was snug and reattached brake. It looks better now. Wasn't sure if this was a big deal or not so thanks for the tip. Sheldon's page had scared me away

I've always been scared of messing with my brakes. But I've gotten more comfortable with all the other bits of my bike, and now that I'm 90 miles away from the nearest bike shop, I am trying to be more self sufficient and brave.

However if you have a bike shop to indulge you, brakes and cables are things I'd recommend you let them indulge you on.

The brakes seem fine now, thought it looks like one is still a little closer to the rim than the other - and the wheel seems centered fine. My ride last night was fine, and the brakes felt/acted normally.

Just in case I am going to swing by my LBS tomorrow and have them take a quick look at it - and ask them to show me what to do should this happen again.
