Brake rotors are warped. This commonly occurs with new rotors, especially those made in China. When we make parts from cast iron we let them age for 90 days before the final machining. When the Chinese make them they cast them, pack them, and ship them right away, then they age on your car. One light machining by the shop that did the brake job is usually all that's needed.
