It is really not a great idea too run a second sets of pads on those rotors. The rotors are certainly well enough worn to warrant replacement. And, for the relative low price of rotors it is not worth all of your time and the potential wasted cost of the pads if you do not replace them. Turning pads is a fools move as far as I am concerned. Most turned rotors warp on the first panic stop. While turning does reface and remove the wear ridge, it does this at the expense of material that is needed to brake and dissipate heat.
Replace the pads and the rotors and enjoy the results.
Honestly, I always replace both at the same time. Why wouldn't you? If you are doing the work yourself,the parts are very cheap.
