I was trying to be civil and not quoting anyone, but since I am now being quoted Terry here is another example of the number of " taps of the brakes" as in snub braking. Notice they mention " taps" not just ride em all the way down the mountain.
Geeeze guys, how long is the Baker grade in S Cali and how hot is it there in July :H
Oh yeah not trying to beat up Ford here, just the facts of the braking tests for the exhaust braking, and number of "taps" rather than riding em. Notice the rotor temps :E the more you tapped the fat peddle.

On edit
