the front brakes on my 93SS were horribly warped. The easy way to check if it is fronts, or rears, or both; drive and slightly pull the ebrake. If you only apply the ebrake and you get Vibration, then it is the back brakes bad too.

Then just apply brakes with pedal, and if the front shakes your steering wheel like hell, then it is front rotors.
Mine were so bad that i think it was actually bouncing my tires up and down, it almost jerked the steering wheel out of my hand at highway braking.

So, off to get the rotors turned. Only 9 bucks a rotor at my Napa store. The other local place that turns rotors wanted 19 each rotor. So I chose Napa to do it.

Rotors back on car now, and smooth as a new car. Very huge improvement on driving enjoyment, and safety as well.

So, moral here, don't always have to buy new rotors, as long as there is enough there to turn them, you will save big $.

and an FYI, usually OEM rotors are good for 1 to 2 turnings before they will be too thin to turn, they are in fact designed so they can be turned a couple times if turned right. And, BTW those ebay rotors are junk.
If you want rotors to last 100,000 miles, use OEM.

some of you will probably disagree on some of the sutff I mentioned.

I think you are pretty much dead on!

where did you hear the bit about checking the rear brakes with the e brake, because that is in a totally different plane of possible warpage than the rotor itself. not saying it isnt possible since Ive never seen a rear rotor warp but please explain.

Errr... like 206er said. The ebrake is totally different than the rear brake. I don't think this will work.

Ebrake won't work.

The standard way to tell...if you feel vibration more in the steering wheel, it's the front rotors. If you feel it more in the brake pedal, it's the rears.

and...personally....turning rotors is a waste of money and more importantly time. I'm not going to get into all the reasons. But the basic one is your rotor is a heat sink. It can hold a certain amount of heat. If you remove rotor material, you reduce how much heat it can hold. In doing so, you more prone to have vibration issues due to DTV, NOT warping.

Here here. I've warped rotors on all 3 of my Subarus, and the couple times I tried turning them it always came back fairly quickly (probably because the problem isn't actually warping, just like you say). I got frozen rotors, and no problems since.
