vibration in front end while braking and the front brake pads changed and rotors turned

Still sounds like warped rotors to me. If you turned the rotors that were on the vehicle when you did the brakes the first time they won't last as long the second time as the rotors are now thinner after turning. 3 years before they started to shimmy again, not bad for turned rotors. You should buy new ones now.
