After having my regular commuter written off, I'm going back to my trusty Cannondale. It's been sat in the shed in pieces so I took advantage of the good weather yesterday to rebuild. All sorted, but I cannot for the life of me get the brakes to work properly. I have watched a couple of videos and read all manner of descriptions but no joy. Essentially they are always rubbing on the rim. Initially they look fine, but after one pull, one of the arms (usually the left) refuses to spring back. The arms themselves are lubed and mounted on the centre of the three small holes where the attach to the bike. Can post pics if none of this makes sense, but if anyone has a surefire method to stop them sticking I'd love to hear about it!
