warped brake rotors - ongoing ?

Just a posting about the historical and ongoing warped brake rotor problem - Jeep Grand Cherokee Laredo 2001 -

I had "serviced" the "warped" rotors at about 15k, 30k, & 45k, replacing them at the original 15k service visit, grinding at the 30k, and replacing again at 45k.

At the 45k mark, I had the standard rotors replaced with some drilled & slotted upgraded versions on the front... Now we are at 54k, and approaching the next 15k interval at 60k. I can almost sense the coming of the steering wheel vibration during braking.

Has there been any consensus about the "warped" rotor problem ? Since I'm now using a different set of rotors, they don't seem to fit into the equation for failure... Some of the past ideas were : rotor material pad material overtightening the lug nuts with impact wrenches

Any updates or other current observations as I approach the next rotor inspection

just an added note ->

There was a Jeep technical service bulletin addressing "the warped rotor problem", that changed some parts of the braking assembly.... That TSB was "applied" on one of the early rotor service visits.

oops - one more web update on the Jeep warped rotor problem...

Your story sounds familiar. I sympathize and offer the following story for commiseration purposes. I bought a new '99 Land Rover Discovery II. I loved it for the first 40K miles.

  1. At 20K miles, I had to replace the front brake pads. 2. At 30K miles, I had to replace a cracked radiator 3. At 37K miles, the starter motor died with no warning. 4. At 40K miles, I replaced all the pads. 5. At 50K miles, I replaced all the pads and rotors. 6. At 67K miles, I learned that the intake manifold was cracked

At 67,200 miles, having never taken it off-road, having never hit a bump bigger than a speed bump, having a trade-in value $6,000 lower than what I still owed on it, I dumped it for a new '04 Jeep TJ.

I have never been happier with a vehicle in all my life than I am with my Jeep. The Jeep and I go off-roading at least twice a month. At 20K miles, the protective film had barely worn off of the front rotors. At

35K miles, not one problem -- mechanical or otherwise.

I guess my LR was cursed. I've not met anyone who has had similar problems -- at least none who'd admit to it.

Do you use a torque wrench on your lug nuts?

It is interesting that I have never done any brake work on my twelve year old Wrangler, other than an occasional inspection of the pad thickness and rotor condition. There is some rotor scoring, but the pads are still pretty thick, and the brakes perform as well as they did when new.

Just last year, I put my first set of new front pads on my '89 YJ. I bought the car at 57,000 and it has 148,000 now. Rotors are still the original!

good point, the torque issue may be the key to the problem....from someone who had to have the rotors "ground" in less than 300000 in an

01 gc while on vacation....

Opps I met 30,000 miles...just wishful thinking about 300,000 miles....

Welcome to the club! I changed out my rotors and pads multiple times. When they overheated and one of the piston boots burned off, I went ahead and replaced the Teves calipers with the Akebono kit.

TSB 05-003-02B is what you want to look at.

Replacing them was pretty easy. The kit even came with replacement copper washers for the banjo nuts.

Note that TSB 05-003-02B is a TSB and not a recall, so if you are out of extended warrenty, get ready to buy the 05093174AA kit (much cheaper than getting the parts separately) and two 52098672 rotors.

Anyone have any luck using pull-off Teves calipers on a YJ?

You've done 750,000 miles on one vehicle ?

Also he doesn't have winter & salted roads to contend with, or for that matter, preciptation of any kind throughout the year.

I used to do 150 miles per day, which took 3 hours ; then I figured it was better to walk to work and spend the 3 hours doing something else. With the latest job, I do 35 minutes each way along pleasantly twisty roads that my Jeep *clearly* wasn't designed to drive along quickly :-)
