You can detect a warped rotor by measuring the lateral runout using a dial indicator, a micrometer that mounts to a stationary part of the car and detects lateral runout in the rotor as you turn it by hand. You could have defective new rotors, or the rotors could have been improperly installed, over rust or dirt, and not mounting flush and flat. Assuming you don't have access to a dial indicator, you could go back to the shop that did the work and ask them to check in this way. I wouldn't assume that just because the rotors are new they are blameless. Good luck.
