I still say it's AIR GUN HAPPY tech's & inproper torque more then bad rotor's

 

Same here well most. Got my "warped rotors" fixed with tire rotation and retorque.

 

Shaginwgn; When my daughter got her 07 LT and I drove it it had a little shake on braking it had 700+ miles on it. took in shop took off front wheels cleaned rotors & back of wheels reinstall with torque and no more shake, Still no shake at 18k now with three tire rotations done my me.

 

I wish mine were a case of over-torqued lug nuts, but they're not. I check them with my torque wrench everytime someone else works on it.

I made the appt. today to have new rotors/pads put on, with GM footing the bill. They had already turned mine 2x before. I can't go more than 4k miles, before I get the shakes again
