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).

New Rotars and pads don't seem to fix.
Steering wheel wobble at 60-70mph
AIR CONDITIONER WAS ALWAYS BLOWING COLD AIR, GREAT IN SUMMER, BUT BAD IN THE WINTER
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. $1400+....
Brake Pulsations, problem not found!
I have the same problem and more . this jeep is the deivl from hell I will never by other jeep again I coul have bought a bran new car for what I have put into this one .
I have had this pulsation issue a few time on mine. I had changed rotors and pads each time, buying me about 6 months. The last time, I replaced my calipers and mounts from the Teves style to Akebono. There was a technical service bulletin (TSB 05-003-02B) issued by Jeep regarding this issue, and the Akebono caliper is supposed to address it. So far it has worked for me.
Pulsation felt when brakes applied.
when stepping on brakes at low or high speed car starts to shake
Mine is a 2014, not 2013. Dealership turned rotors on the lathe. Problem repeated itself less than 10K miles later. Deealership tried to tell me I must "ride the brakes" or drive aggressively. Hah! I commute to work 25 miles each way. Some stop and go traffic is all.
I've had the disk rotors turned twice and finally had to replace the rotors themselves. After I had the rotor replaces and a non-Jeep dealer I haven't had any problems for the next 75000 miles!
Rear brakes hot. Groaning noise
Had same problem and just go it fixed. Had new rotors and pads put on. Problem is now fixed
Front rotors warped, replaced, back rotors and pads badly worn
When I come to a stop the breaks sound like they are grinding and skipping. It makes the whole Jeep shake and is very loud and very embarrassing. After a few times of stopping and going the ABS light kicks on and everything works like it should. I was told it would cost 1200$ just to diagnose the issue because the jeep dealership I took it to claimed they've never seen anything like it. Which worried me.
Rotors keep warping every 10,000 to 15,000 miles. The correction or at least an improvement requires replacing the calipers. The 2003 came with these new calipers (Akebono). Not as much of a problem with the pistons freezing up on the new caliper. Check WJJeeps.com for the correct part number to fit your application.
severe vibration while braking @45 mph and above.feels like losing control of vehicle. new rotors 3 yrs in a row,last included new calipers. now it's back again.
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.
Brakes had to be replaced several times because of severe brake pulsations!
I have to change the rotors every six months!
