In regards to the jeep grand cherokee brake situation, I was listening to the show while driving my 2000 Jeep Grand Cherokee, and felt the same brake issue because I haven’t repaired it yet. Talking back to the radio didn’t help the boys provide a better answer.
The diagnosis provided was correct; it is warped rotors, but simply replacing the rotors will not fix Shawn’s issue on his 2001 Jeep Grand Cherokee. He will continue to warp rotors the more he drives.
The rotors warp on the 1999-2002 WJ’s due to the poor design of the Teves calipers that don’t center well, they drag, create heat and warp the rotors. The only way to really eliminate the issue is to replace the Teves calipers with Akebono calipers. Jeep issued a TSB on this (#05-003-02), and Jeep started producing the WJ with Akebono calipers in May of 2002.
