Violent pulsing/shaking when braking

[JIM_C]

My truck in sig has 95k on factory rotors, never turned. Pads were replaced at 80k and the shop used some pads from Advance Auto down the street. Worked fine at first but is getting worse quickly. It's ok at slow speeds but slowing down from faster than about 60 causes the whole dash and steering wheel to shake.
I'm thinking warped rotors in front, maybe because I didn't tell them to check and lube cylinders/pins that run the calipers (nothing was said about that so I doubt they did anything besides replace pads and look at rotors).
I'll check for loose front end components tonight but what do y'all think?
I plan to keep the truck for a while so if other front end components check out OK I'm thinking I should get new OEM rotors and hawk pads along with servicing the cylinders and pins.
Could el cheapo pads from Advance have warped my rotors or is it more likely that the calipers are messing up?

More than likely warped rotors, I just had the same problem and took mine to my buddy's muffler and Brake shop and got em machined back down for $80 and now it's completely gone!

I tried turning my rotors once, what a joke! I'm lucky if I get 50k out of front rotors so I second the notion that yours are warped. Since your pads are new, I'd swap out the rotors.
