rough braking ??
I get rough braking, feels like it might be coming from the rear but not too sure.64 K and I changed the pads about 25K ago and I looked and the pads are fine, one of the rear rotors was a little scared but not much. I guessing I should start by replacing the rear rotors, but not sure. How big a job is that? Any help would be great .

He might be referring to the infamouse "pulsating brake pedal", which is typically caused by uneven pad deposits on the rotor. I experienced it first-hand at 6000 miles and again at 12,000 miles after the dealership turned the rotors shortly after the first incidence.
My solution? Slotted rotors. (PowerSlots) I now have almost 37,000 miles and have not had any pulsations for over 15,000 miles. As an aside, the latest Viper ACS and the Cadillac CTS-V have slotted rotors on them from the factory. It's about time!

The hardest part about changing rotors is removing the caliper bolts. The 2 bolts that are 21 mm are the hardest part because they are usually very tight. My impact max 380 # torque wouldnt touch them. I had to put a pipe on the end of a breaker bar for leverage.

I am pretty sure it the rotors, it really doesnt fell like its pulsing or really that rotors or warped, just almost feels like metal to metal but it is not metal to metal. I guess its a good excuse to upgrade.

You would be correct, you need to replace your rear rotors and no it is not a difficult job 
Remember that the e-brake is inside the rotor, built into the rotor like a mini drum, just make sure that you have the e-brake released when you remove the rotors and they should come off fairly easy.
You could call Gene Cully from GM Parts House and get a set of discs for a great price or go to NAPA if desired
Thanks,Matt
