Like everything, it depends on usage. The discs have a minimum thickness
marked on the hub and can easily be measured. I've found they last for two

It is normal that brakes and pads are replaced at the same time, but typical
life is two sets of pads for a set of rotors. If your braking leans to the

rotors. Frankly, if you need pads after 30k miles, you are pretty hard on
them. Of course, if you drive in constant stop 'n go traffic, then your
brake life will be shorter, and this could explain how you need brakes
already. I am not alarmed that you need brakes, but I question if you need
