Warped Rotors A Myth?
http://www.stoptech.com/whitepapers/...otors_myth.htm
What do you guys think of this?
It sounds plausible, but I'm not sure I buy it yet. I've seen rotors that are actually warped, and I've tried turning them to no avail. Granted, these instances were more than likely from people with impacts putting lugnuts on.
I'll give it some time to simmer and see how I feel about it later

Not too sure what to think....
I have always installed the new pads and rotors and torqued the wheel lugs in the proper sequence to 100ft lbs... I have always warped rotors on my 95 bonneville no matter what I do... I have tried every pad, and replaced rotors 3 times in the 7.5 years I have had this car... The result is the same for both sides everytime... My rotors are showing signs or warp again... It really got nasty as I was driving thought Orlando traffic...
My 91 is on 5 years with the replacement rotors and AC Delco Pads.... They are just starting to show signs of warp... I'll be replacing the rotors and pads in the near future... Being as old as the car is I might replace the brake lines as well and bleed the system...
Anymore I do not trun rotors, I simply replace them... Rotors for my 91 are cheap, and the ones for the 95 aren't a whole lot more.... I have turned the rotors for my 95( original factory set ) and that turned out to be a mistake... The first time I hit bad traffic and the rotors got good and hot I could tell they were warped...
My good friend has a 92 Park Avenue, he also had the same issue... New pads and new rotors corrected his brake pulsating problem as well...

Don you also drive in rain/water more then a lot of us do, and if your rotors are nice and hot, and get splashed by a lot of water they can warp very easily.
This happened to me on the way back from TO, i had to hit them hard before a clover leaf, and hit a huge puddle after that. They sure pulsed more at the end of the trip...

Yes the sometimes heavy rains will cause problems... Thats if the brakes are hot tho... I seem to get throught 1 full year, after that I start to notice the problems return again...
I have fought out the rain and rotor warp connection, Yopu know it happens, I know it happens, I've had some say that its not possible... If we can warp and alluminum head, and crack a cast iron hear, we sure can warp a rotor due to sudden temp changes...
Back to the 91, this car has been through the same as the 95, and just starting to show problems... Gotta love these cars.... Thank god rotors are cheap and easily replaced...

I thought I'd add two cents on this one..... I work for a German auto manufacturer (who shall remain nameless) in Michigan as a warranty analyst. I see just about every type of failure there is on a car everyday. I can tell you that every person on our product support team would absolutely agree with what was stated in that article. They stress that a rotor does not "warp". They would agree that a pulsation would normally be attributed to pad material transferring to the rotors. I'm not saying that I personally agree or disagree, just thought I'd throw this out there.....

I could see the pad material building up on a slotted rotor or drilled rotor....But building up on a plain jane smooth surface rotor is pretty bogus to me.
