1)My bike has a dial on the front brake lever (1-5). Is it for brake sensitivity or does it adjust the distance of lever to grip?
2)Also, when I am rolling the bike (without ignition on), I hear a sound (rubbing or scuffing) from the front brake area. But when I lightly apply front brake, the scuffing goes away. Is this sound (brake drag) normal?
Thanks all in advance for your input and help.
