Yes, I know it's anti-lock and when it's being use in a hard braking situation the pedal pulses. However, during normal braking mine does pulse, but not as actively as during the other time.

Any thoughts??

Could be a warped rotor

I did have them turned about 1.5 years ago and I guess they could be worn again. Hafta check...... THANKS

You know every mechanic I've ever been to has recommended against turning rotors, with several of them refusing to do it at all for safety reasons. Obviously they have a vested financial stake in replacing them, but anybody agree/disagree with that opinion?

It does seem to be the considered opinion of just about every mechanic out there; replace, do not refinish the rotors. Kinda sounds like a profit and liability issue!

My brother is an ASE certified Ford mechanic and they have no problems turning rotors. The thinner the rotor, the easier they are to warp though. Also, they have to still be within spec for the application (obviously). They can't file off so much material that the rotors are thinner than accepted for that vehicle.
My experience is that a lot of tire shops etc that mount wheels with impact wrenches are the reason rotors warp. Or by tightening down one lug all the way to spec without working them all down in a criss-cross pattern.

Think the fronts need to be just to true them up with the hub

Agreed. true. myself cert canadian mechanic. But, sometimes cheaper for cust to get new rotors then lathe the old ones.
