brakes pulsating
I bought a 2008 Tahoe about a years and a half ago. I have had nothing but problems with my brakes. I have put all new brake pads and rotors on three times now. They last about a month then start to pulsate. My brake pedal does not feel right and has play in it. Brake fluid is full and has been bled each time I replace them. I also have an issue with my cruise control not wanting to work. I have to take my foot and press up on the bottom of the brake pedal to get it to work. I have taken it to the dealership as well as Les Schwab and they continue to say there is nothing wrong with it aside from needing the rotors and brakes replaced.

Your brake sensor is shot. It's a $11 part and easy to replace.
as for the vibes - I'd try rotating the tires as well - couldn't hurt.
also, if anyone is even resting their foot on the pedal - it's applying pressure and the heat will warp the rotors over time. I've seen many cars going down the road - brake lights on!
I've also found heavy towing accelerates the front pad vibe...

I have had to put new rotors on the front only once when I bought it. It seems to only be the rear that's the issue as I have had to replace them three times and every time I do the pulsating goes away for about a month than starts again.

the brake sensor is unrelated. I've also noticed some pulsing that goes away if you replace the front rotors, but does eventually come back. It's not bad enough to warrant much on my end. Maybe it's worse on yours.
What about new calipers? You've replaced everything else...

No, that's my next job. Actually doing it this week. I am thinking that the rear caliper pistons might be sticking and causing the issue. I had to put lube on them once when I bought it due to some sounds they were making.

Also going to replace the master break cylinder as well. after that I don't know what else it could be. Was just hoping someone on here would know. If that don't fix it I will replace the rotors and trade that sucker in. lol
