Steering Pulsing 2012 Suburban

I bought a 2012 LTZ with 120k miles on it a few months ago. As part of my purchase I made the dealership completely change all the fluids and they had installed a new battery and worked on the front brakes. Ever since I got it there is a slight pulse in the steering the steering wheel when braking. I've had warped rotors on other vehicles and this feels like they could have a slight warp (if that's the issue). Anyway I had the oil changed and the shop took the fronts off and turned the rotors - they said the outsides were slightly warped. Anyway after all said and done, that didn't take the pulse away. Is the power steering tied into the brake system like it used to be in older GMs? Curious if any of you veterans can offer some input.

Thanks!
