Hell, i'm really gettin sick n tired of my rotors, which i don't know why, always ends up bent. I don't squirt water into it when its hot, my alighments all perfect, i have a new set of rims and tyres. Still, this piece of shit gets bent for heaven knows why.
Each time it gets bent, i get it skimmed( together with the pads) and it drives good but only for a while before the shit starts again.... Anyone have a clue??

I read about this in motortrend a while back. It has to do with braking practices. They said if you brake hard repeatedly, even the best rotors will warp after time. They heat up so fast and then cool down just in time to get hot again. A guy with an Oldmobile wrote in and asked the same question that you did, right down to the turning. Hope it helps.

I assume you mean you get the rotors "turned". You also need to check minimum thickness on the rotor. If it gets below min spec, it probably will bend easy.
I have heard other owners say they replace the rotors everytime they replace the pads. I haven't run into that problem (yet).

Knock on wood - for what it's worth - I've had my stock rotors on the track at about 1000 degrees F and not had a warping problem. They have about 75% of the wear allowance left on the rotor. I would guess your rotors are worn out (out of tolerance) or some other factor is causing the problem. Are your rotors stock? Are they hand torqued in a star pattern when the wheels are put back on the car? Improper torquing process on the lug nuts can cause warping on some cars. Some aftermarket rotors are inferior and more prone to warping than a good quality rotor. Your really shouldn't be having the problem with in-tolerance stock rotors that have been torqued correctly.

Rotors usually don't" bend" the get warped from heat.

The min thickness for rears is 15.00mm[.591 in]


" " fronts is 28.0mm [1.102 in]

If there any where close to these #'s don't cut-em' replace-em'.

specs are for 93.5-98 tt
