I will check them tomorrow.
Do you think that the brake and ABS lights I am having are due to this odd brake wear problem?

The ABS light will set a trouble code. Most common problems are wheel speed sensors. I would say the lights are not related to abnormal wear.

I pulled out my trusty Harbor Freight code reader and it did not show any trouble codes.

Crappy factory rotors, mine did the same thing. I had the rotors replaced under warranty and the new set did it too. Replaced them myself with some aftermarket "performance" rotors, and they're still going strong some 7+ years later

Mine were just like that only five times worse. I replaced them with OEM rotors and what a huge difference. I cant believe I didnt drive up someones *** before.

How does your brake fluid look? Is it full? I've seen the lights come on just from low brake fluid. Are your brakes noisy?

I was not able to check my truck today. I will check it out tomorrow and post up what I find.

My factory rotors did it, too. I cleaned them up on a brake lathe, and they did it again. If EBC makes replacements, that's what I'm getting. My mom's Cobalt did the same thing and I replaced them with EBC, they're great now. It must be some awfully crappy metal that GM used.

I pulled the rotors off today. The pads were only making contact with half of the rear side of the rotor. The fronts were a little better at 2/3 clean contact area. I can't believe I didn't have braking problems.
Until I get new rotors, I sanded the old ones down. They will work for now.
Here are some pictures.
