You do not want to ride the brakes but rather quick jabs a bit apart so the brakes don't heat up. I have been known to pull off in the truck pull offs for brake checks prior to going down the mountain. I slowly let myself get up to speed. What gear did you climb the mountain in? The low gear you used going up should be a good indicator of what gear will be needed going down the mountain.
Thanks. Coming up, gearing was 3, then 2, and a little short stretch, it was 1. I like to keep the tach above 2500 rpm, but I don't like to go over 3500. I know the 5.3 likes the high RPM, but after taching 2000 at 70mph when not pulling a camper, that high rev. Is kind of unnerving.
