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+

Braking from 55 mph the steering wheel shakes substantially; dealer reported front and rear rotors need replacement due to warping. Brake fluid compartment has "rotted" and needs replacement. $1400+....
I have had this pulsation issue a few time on mine. I had changed rotors and pads each time, buying me about 6 months. The last time, I replaced my calipers and mounts from the Teves style to Akebono. There was a technical service bulletin (TSB 05-003-02B) issued by Jeep regarding this issue, and the Akebono caliper is supposed to address it. So far it has worked for me.

All 4 pads worn all the way down. Had to replace rear rotors due to "Rust groove" and had to turn front rotors due to being warped. Still have front brake issues.

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!

Brakes had to be replaced several times because of severe brake pulsations!
I have to change the rotors every six months!
