Warped Rotors?

Hi all,

I own a 2007 Mazda 3 GT and recently I notice that when I hit the brakes my steering wheel starts to shake. Could this be because my rotors are warped?
If they are warped should I have them machined or buy new rotors? Any info will be greatly appreciated. :(
 
It’s a typical sign of warped rotors. You can inspect them visually and not just assume that both front and rear pairs have to be replaced, however.

It could also be uneven pad deposits on the rotors. If you get the front rotors turned (machined) or replaced, definitely get new pads and have your brake fluid flushed/replaced.
