Front brake float & rub(3 posts)

I've put a few thousand miles on my bike and recently the front brake has begun to float around during a ride. About 10 miles into a ride I suddenly get one of the brake pads rubbing against the rim because the whole assembly seems to turn around the bolt. These are RSX components. The wheel is true and there is no excesive play in the hub, so it can't be the wheel knocking the brakes out of alignment. What could be the reason and is there a simple (i.e. no replacement) solution? Thanks.

Not to be flip, but are you sure the bolt that holds the brake onto the bike is tight? It's probably a 5mm allen bolt that you tighten from the back side of the fork. Hold the caliper as straight as possible while you tighten it.

There is also a tiny screw on one of the brake arms. It's purpose is to allow you to adjust the release spring tension so that the two arms release together when you release the brake lever.

Hope this helps.

stick one between the back of your brake and the fork and it'll stay put. Your LBS will know what you're asking for.
