I have a BB7 on the back and the disk rubs almost constantly. I have checked if the rotor is warped but it isnt (or not significantly - i'd say less than a milimeter but it does wobble up a down a bit more.) The problem is whenever i try to fix it, i jump off the bike hold the back wheel off the floor and spin it. Nothing. No rub. No Zing. But i get back on the bike and the rubbing will start again. It isn't the usual zing...............,....zing..................zing ............ as the rotor goes round, it rubs almost constantly. So i move the pads out and it still happens. The only time it stops rubbing is when i move the pads almost completely out resulting in no braking force at all. I've tried re-aligning the caliper using the manufacturers instructions and the brake FAQ on this website to no avail. Anyone have any ideas on how to fix this.
