I have an 04 Dakota 4-door V-8. I have owned it for 1 year with 30k miles on it. I have had the rotors replaced 4 times. Anyone else? Anyone with clues as to what is going on? I do not tow anything, yet, but as you can tell by the mileage I do a lot of highway driving.

Did you double-check the wheel nut torque after the rotors were replaced?
Repair facilities are notorious for using too high an air wrench setting.
Use a good quality torque wrench and retorque them to 100 ft-lb using a proper cross-bolt pattern.
The reason this is important is the rotors are not bolted to anything; they are sandwiched between the wheel and hub. It's my opinion that uneven torque may contribute to this ongoing rotor problem.

Also, follow up whenever the tires are rotated. Tire shops are as bad as anybody about overtightening lug nuts. I dare you to try to change a flat after they hammer those lugnuts on.

Yep I own a 1998 Dakota and I have replaced rotors 5 times. I got an e-mail from About.com that identified the problem. Dakotas and other cars have this floating hub and rotor design. Even though the runout is within SPEC say at the hub the runout near the edge of the rotor could be a few more thousands out. Each time the rotor rotates it hits the pad and causes a hot spot and warps. To remedy you have to clean the hub and rotor really well and then turn the rotor on the car which trues the rotor to the hub. I did the torque deal and even had them torqued by hand. (Must be in a star pattern). Never worked. Now the trick is finding a shop with an on the car brake lathe. To date the only ones with them are the dealers. Now Ford has called for theses designs to have rotors turned on the car. I had my Dakota at the dealer for brakes and they still warped. I asked the dealer about the problem and he insisted it was bad torquing and later said it was from stop and go driving. When I brought in the reply I got from About.com, he said "Oh yea, Chrysler has been calling for on the car rotor tuning for 7 years". I believe their is a design flaw and admission of it by any Manufacturer could cost them a lot of money. At any rate FOrd dealers can also perform on the car rotor tuning if you can't find an independent. Drilled and slotted race rotors could work but I expect they would also eventually warp, and often those rotors are not turnable. A side note is that if you let it go too long it sets up a resonant frequency in the caliper piston which causes it to seize and ruins the rotor. I had that happen too.

Hi All
I had this problem not long after getting my 2001. It seems that the factory rotors are a bit on the thin side. Any hard or prolonged braking will over heat them and cause them to warp.
This is called, "ENGINEERED FAILURE"
Chevy is very good at doing this trick.
It may be best to find an after market product.

Here's a link to some interesting info from a brakes symposium.
http://hostingprod.com/@aa1car.com/library/procut3b.htm
It's a bit dated, and I couldn't get the links at the bottom of the page to work for me.
Still quite informative.

Wow. Thanks, DanK
What a dry, boring read.
But you're right, there's some good stuff hidden in there about how the big 3 auto makers feel about the quality of the brakes they put in their cars.

2002, 4x2, 40k miles => This weekend I changed out the warped factory roters for new aftermarket ones. I noticed severe "pitting" on the surface. On closer examination, it looked like flaws in the metal rather than corrosion. The guy at the "brake and equipment" shop said "ya, they make the cheap ones like that" . . .

and you can bet the guy at the brake and equipment shop put on ones of the same quality as the ones he just took off.
