My wife just logged her 400th mile today on her '08 Specialized Tricross Sport triple and her rear pads are still rubbing. I've removed them and cleaned the pads and the rim and still they rub on light braking. She hasn't had to do any hard braking at all - no true panic stops; no technical descents at speed, just flat rides around the area w/very slight ascent and descents. Are we still in a break in period? I've never really had an issue like this, so, I'm somewhat clueless.
Thanks in advance.

Why did you clean the rim and pads instead of adjusting the brake? It isn't going to adjust itself!
You can just turn the barrel adjuster in to open up the brake a bit more if it is too close.
If you pull the lever and the pads start 'rubbing' the rim/stopping the bike I would say that is a good thing, if they aren't touching during normal riding, which sounds like the case here.

Didn't realize I said they were rubbing when riding... They rub with light braking being applied...they are adjusted.... hmm interesting forum this one.

Confused, if you're doing light braking, what's wrong with the pads hitting the rims? If they're rubbing when not braking is it because the wheel's out of true or the brake needs adjusting?

They are supposed to touch the rim under light braking... if that is an issue you can back off the cable a little to increase the pull needed before the brakes engage but it begs the question... why ?

Only thing I can figure is we're misusing the word "rub" and "rubbing" and the OP means "squealing"?

That or maybe he means they just intermittently rub under very light braking - ie, the rear wheel's out of true.

So they rub when the bike isn't being ridden and you pull the lever? I am so confused.

The "adjustments" don't wear in. They can be perfect the instant you set them up _properly_. Which is what you need to do. This is of course assuming that the wheel is true.
