Why are my bicycle brakes rubbing and how can I fix them?

Your bicycle brakes may be rubbing due to misalignment or wear. To fix them, first check for any debris or misalignment in the brake pads or calipers. Adjust the brake pads or calipers as needed to ensure they are properly aligned and not touching the wheel rim. If the issue persists, consider replacing worn brake pads or seeking professional help for further adjustments.
