Best response, so far, is from Handbasket. Technique and speed control is the best way to control brake temp. If you go up a 7% grade at 40mph, you go down the same grade at 40 or less with the tranny geared down. Recently I did a switchback ride of almost 15 miles and a 7-9% grade. Truck and loaded trailer pushed 16,000lbs and the tranny never left 2nd gear and averaged 25mph. Used the brakes about four times. I still stopped at the bottom pull out to check truck and trailer brakes. I think the twenty-thirty extra minutes I spent was a lot less expensive than replacing the brake pads and rotors.
In the coach, loaded, I tend to travel in traffic well under the speed of others and don't mind the stares and gestures. Even then, I seem to be about a few vehicles behind the speed demons at the stop lights.
