If that were true, all the stock daily drivers at the track would have uncontrollable wheel shake. It used to happen on mostly non-vented, crappy quality rotors years ago. A similar effect can happen from pad deposits (even looks like a warp when cutting the rotor) because shitty pads are still out there. ---

Hai. Just checking back in again. There is some truly great misinformation in this thread. 😃 Just take your car somewhere instead of trying these little tests. A trained tech will look at your car and have it diagnosed in under 5 minutes. ---

Grind smooth with die grinder and cookie or get new ones. Then you must grind down the area behind those metal plates that they attach to / rest against. Otherwise the pad will be too tight and won’t be able to move properly and it will hang up. Possibly causing your warping. Make sure to use loob where the pad slides as well, but don’t get any on the pad face or rotor like a n00b. I also like to put a tiny bit of lube on the back of the pads where caliper touches to help prevent squeal. ---

I have not noticed anyone asking of the hub-face runs true or not. this can easily be checked with a dial indicator and a magnetic base. Most likely the car has bumped a curb, and the warped feel is disc run out, or most likely pad transfer. I wont get into how hot something SOLID needs to get to change shape, but something cast is a whole other ballgame cast things will break but do not really exhibit ductility. Certain metals will move more than others at temp. your rotors may indeed may distort slightly but the effect is not permanent. Generally glowing is i sign that a material has reached a point of internal energy that the material will reform inter metallic bonds. This does take time however. Generally at least 3 hours at a glowing temperature, some up to 20 hours to do their thing. You will see brake rotor surfaces glow at the track, especially Subaru’s for some reason. The material strength is severely compromised at temperature, but any sort of permanent deformation is unlikely. ---
