Sorry, Horum, you are right I did misread your question, and yes, I do like to put the car in command shift for quick launches and passing, but not as a general rule do I leave it in command shift or do manual shifting unless I am driving in the mountains. (Hilly Highways, etc.) I'm sure engine braking takes the heat off the brakes, but in my mind, that doesn't explain early rotor wear. I guess I will have to have them physically show me the "cupped rotors" and explain that to me. Anyway, I guess like jptruck stated earlier in this thread, I'd rather not have brakes that sound like an '84 Chevy Jimmy either.
