my '06 tj with 5000 miles on it .....and the brakes are pulsating ......is this a common problem .....don't want to turn the rotators this early.....maybe its under a recall or warranty thanks > my '06 tj with 5000 miles on it .....and the brakes are pulsating > ......is this a common problem .....don't want to turn the rotators this > early.....maybe its under a recall or warranty thanks Did you hit a large bump and bend the rotors? Probally overheats them and runs through water. >> my '06 tj with 5000 miles on it .....and the brakes are pulsating >> ......is this a common problem .....don't want to turn the rotators >> this early.....maybe its under a recall or warranty thanks > > Did you hit a large bump and bend the rotors? > my '06 tj with 5000 miles on it .....and the brakes are pulsating > ......is this a common problem .....don't want to turn the rotators this > early.....maybe its under a recall or warranty thanks This is extremely common and is normally caused by putting the tires on with an impact gun. They are supposed to be finished up with a torque wrench. You can buy torque wrenches for under $30.00 that are good for finishing wheel lug nuts or making sure the tire change pricks aren't trying to sucker you. It would seem one of the latest scams by some $tealerships is to get you in for a 'free' tire rotation, hammer the wheels on with an impact gun and sucker you for a brake job.

Jan/06 http://www.imagestation.com/album/pictures.html?id=2115147590 (More Off Road album links at bottom of the view page) I agree that it is extremely common, but not that it is "caused" by the impact gun. I have barely six thousand miles on a set of new rotors, and they are already pulsating a bit, along with Autozone "lifetime" pads. I put the wheels on with a torque wrench, of course. Maybe I drove the vehicle in the rain, or made a panic stop or two, but what the hell are you supposed to do?

Maybe I drove the vehicle in the rain, or made a panic stop > or two, but what the hell are you supposed to do? proper brake-in (pun intended) is key to long brake life. http://www.stoptech.com/tech_info/wp_warped_brakedisk.shtml The procedure is basically a series of increasingly quicker stops from increasing speed, followed by a drive to allow the disc to cool. What you want to avoid with new brakes is to run hard, stop hard, then sit there at the light with your foot on the brake. That traps a lot of heat under the pad and will start the warping process.  SignatureDougW > proper brake-in (pun intended) is key to long brake life. > http://www.stoptech.com/tech_info/wp_warped_brakedisk.shtml Good article. I was reading the latest JC Whitney motorcycle catalog at lunch. During the week I had, among other things, relined 25 sets of vintage Lotus race car brake shoes with NOS Ferrodo asbestos linings. This stuff is nearly impossible to find and prized by vintage racers. The catalog shows brake shoes and pads, "made with non-asbestos low friction linings to avoid sqeaking". Low friction brake linings? For those times when you really don't want to stop? What next, high friction oil?

Kaleco's cross drilled brake lines. http://www.kalecoauto.com/ They don't have high friction brake oil, but I'm willing to bet they would carry it. :) SignatureDougW I don't know if Jeep has learned anything useful from Mercedes, but my 300TD uses soft nodular iron rotors that should be replaced rather than turned. They seldom make it thru a second set of pads without warping, but they are cheap, designed to be sacrificed. They can be bought for as low as $17.30 each. SignatureStupendous Man, Defender of Freedom, Advocate of Liberty Hi Earle, Agreed, Daimler's composite rotors and weak hubs are the problem. I've slammed thousand of wheels on the Real American cars, and trucks without a problem!

Any competent mechanic should have a set ot torque sticks. http://www.sjdiscounttools.com/ameext50.html I wouldn't use them on an aluminum Porsche hub, but for iron they are great. If you want to be finicky, use the next lower range and then torque by hand. SignatureStupendous Man, Defender of Freedom, Advocate of Liberty The tire shop I go to has a set of torque spec standards on a doorway to the parts room. First order of business in the morning is to take the manual clicker torque wrench and check it's accuracy. Then all wheels are finished up using a torque wrench. >>This is extremely common and is normally caused by putting the tires on >>with an impact gun.

If it's ABS then have them check the front sensors, one is either out of range or close to it. If it's drag/release (warped rotor) then it may be a MFG defect. Long as your under waranty I'd have them diagnose it. If the finding is warped rotor, and you have to go out of pocket to fix it, your better off buying new rotors and installing them yourself. It's not a hard job. Basically, if you can change a tire you can replace a rotor. It's just two more bolts. SignatureDougW Hi Doug, I think you've got it! And the Poster is in an extremely dangerous situation!

SignaturePosted via a free Usenet account from http://www.teranews.com 5000 miles is obviously too early to be having to deal with problems like this. But your dealer will tell you that rotors are 'wear items', not covered under warranty. but it is worth a try to see if they will cover it. I would not turn a warped rotor. Every time I have tried it, I get only few miles before it reoccurrs and it's off to get a new one. Say what you will, the aftermarket cast rotors can be had for not much more than turning. > my '06 tj with 5000 miles on it .....and the brakes are pulsating > ......is this a common problem .....don't want to turn the rotators this > early.....maybe its under a recall or warranty thanks it's a warranty thing > my '06 tj with 5000 miles on it .....and the brakes are pulsating > ......is this a common problem .....don't want to turn the rotators this > early.....maybe its under a recall or warranty thanks > it's a warranty thing > >> my '06 tj with 5000 miles on it .....and the brakes are pulsating >> ......is this a common problem .....don't want to turn the rotators this >> early.....maybe its under a recall or warranty thanks 'If' they will warranty it, get new rotors. One other 'scam' reported is to 'fix' it free under warranty by turning it so when it runs out of warranty there is no turning left and you them must replace it on your dime.
