Your rotors are warped. How old are the front brake pads and rotors?

It really sounds to me that the rotors are warped. Consider picking up a fresh set of rotors. Don't buy the AutoZone cheapies. You'll get what you pay for. I suggest going to Napa. Get a fresh set of pads too. It'* not wise to run used pads on new rotors.

Rotors are what the front pads clamp against. Remove the wheel, remove the caliper, then remove and replace the rotor. Both the fronts. Do pads again, too.

One more thing... Don't bother having the rotors "turned". The vibration will return very soon.

Little bit o background.

The reason rotors warp are either excessive heat or the material remaining is too thin and the heat warps them.

For either reason turning or resurfacing (removing material) will only result in excessive heat and more warping.

Here'* a link that shows the difference in rotors.

Also keep in mind when buying new rotors, you get what you pay for... You pay for cheap( Junk ) you get Cheap ( Junk )
