You can believe what you want, however IMHO, here is why rotors warp.
When you are driving along, at a good speed, and a traffic light changes to red, what do you do? You slam on your brakes, right? OK, when you stop fast and hard, at a light, what do you do next? You sit there at the light, with your foot on the brake, hot pads on hot rotor. That rotor gets "heat soak". That is, the section of the rotor on the pad gets hotter than the rest of the rotor. When you start off again, that part of the rotor that had heat soak, is just very slightly warped because of the temperature difference. Do this often enough, and before you know it, the rotor warps enough that you can feel it when you brake. Having the rotors very hot in itself is not a problem, but having one section of a rotor much hotter than another section of the same rotor IS a problem.
Here is what I do. A pain, but I do it often. When I have to stop fast, while stopped, I either: (1) put car in neutral, and remove my foot from the brake,hot pad not pushing hard on hot rotor] or (2) once I stop, while still in gear, I allow the car to roll (very slightly) forward, very slowly, so the pads cover the whole rotor, being careful not to roll forward enough to get into the crosswalk or cross lanes.
I do this every HARD stop, and I've done it for years. Sometimes I put it in neutral even after easy stops, waiting at a light.
I NEVER GET WARPED ROTORS, and have not had warped rotors in over thirty years. (HOWEVER, my wife does not use my method, and her Lincoln gets warped rotors - no use trying to tell her what to do as that would only lead to an argument - I was born married).
this is true! this is exactly why many rotor manufacturers says do NOT come to a complete stop when bedding in pads.....but this isnt the only reason.
to people in this thread to clear up information:
92 accords have captive rotors......pita to change
all hondas in general require 80ft pd torque on lugnuts. you can go higher, no point but what you want is consistency.
