I have a 2001 Supercrew and I am warping rotors way to fast. I have replaced and turn rotors and pads and checked the suspension. I just don't know were to turn now.

 

When you put the lug nuts on or someone else does it, do your torque them to 150 ft lbs. Unevenly torqued lug nuts is probably the main reason rotors warp. Since I started doing that to mine on the different vehicles I have had, I have yet to need to get the rotors turned or replaced. That has been 14 years and about 400,000 miles.

 

I always do it myself and I didn't know that. I will do that from now on thanks.

 

Read this.

 

Torque sticks are nice, but I still would not trust them over a true torque wrench. Better than guesswork, and great for the mechanics who do a lot and can'tt take them time to constantly set and reset a torque wrench. Far better than guessing the right torque.

The chart only goes to 97, which had 12mm lugs. Those were torqued to 100. In very early 2000, Ford changed to 14mm lugs. Those are torqued to 150.

 

That is great info guys thanks very much.

 

Rotor warping is also cause by using non-compatible brake pads with certain rotors...
OEM pads are better than Motorcraft, and cheap ones will warp your rotors with no mercy...

what are your driving habbits? that has a lot to do with it too. you nail the brakes at the last second, tow heavy loads, or go 100mph and nail the brakes?

 

I have an older F-150 (95) that had the same problem when I put 33 tires on it. If even torque on the lug nuts doesn't fix the problem SUMMIT RACING sells a set of drilled rotors that worked for me. I would have to look up the name but, to my knowledge, they only carry one brand of drilled rotors for trucks (or at least just on for my 95). I tried alot of different rotor/ pad combos before I fixed the problem w/ these rotors. They are under $100 a piece and I used the pads the rotor manufacturer suggested.

Good luck, Nick

 

My driving habits are normal. I travel for work and drive my own truck. I always use ceramic pads. I do put alot of miles on but that is about it.
