Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).Google+

I've had the disk rotors turned twice and finally had to replace the rotors themselves. After I had the rotor replaces and a non-Jeep dealer I haven't had any problems for the next 75000 miles!
