Here's a strange one. When conditions are dry my front Avid BB7 disc brake will not stop me. It's so bad that I can pull the leaver, push the bike and the front wheel will move a little. But when it's wet out and the brake is wet it works perfectly. I have new Avid pads and have cleaned the rotor. The brake is properly adjusted. The rear brake has no problems.
Do you have any idea what could be causing this and how I can solve it? Thanks.
