I live in the Eastern Sierra, and, for example, the road that leads to
the campground above town climbs over 5,000 feet from 3,975 ft to
9,300 ft. in 13 miles, averaging 7% for the entire 13 miles from my
home. I always use the braking force of the compression of the engine
when I come down a very long grade like that.
I wouldn't worry about it damaging your engine or transmission. It
puts less stress on them than accelerating.
The brakes on my 300 TDT are very good and well designed to transmit
heat. They are unlikely to fade under most circumstances, but I still
use engine braking always on big mountain grades and so does everybody
else who lives in the mountains who knows how to drive properly. I
have had brakes fade once or twice when I was driving VW buses long
ago, and it is pretty scary because suddenly your brakes will not stop
or slow down the car.
I have never had that happen with a car with 4 wheel disk brakes
though, but, then again, I always use engine braking. It's something
my father stressed when he was teaching me to drive.
Gentlemen: I need some advice.
