    I'd like to clear up a that I do not use the stab brake method. I believe that stabbing the brakes puts too much pressure on the brakes and heats them up too fast. With what I described there's more time with no braking (allowing the brakes to cool) then braking. We only had a single stage engine brake at ARCO but I have drove a truck with a 3 stage engine brake. But I never had that luxury when I was loaded up. I came down the I-80 grade into Salt Lake City at 110,000lbs and had no engine brake at all. So just to be fair to any new drivers that might be watching I posted this message to cover all the different situations the driver might find himself faced with. I have found times that the engine brake didn't work at all but the load still needed to go. All the answers have been good and I thank you all for that. I think the main message that got across was to slow down. We've all seen the hot shots that fly down the grades and I just wonder how long they have been driving or how long they are going to drive. I believe that today's CDL schools do not teach or put the time in to show these drivers how to go down the grades. Or alot of other necessary technics to make the job safer. Thanks to all.

    I recall one time when a team of women driving for u.s. express were full smoked as they pulled into the rest stop on mt. ash land in the siskiyous
    n.I-5 in oregon right where the grade leveled out and was a smooth ride to port of entry. years later they closed that rest stop after a truck W/fullysmoked brakes could not stop as it barrelled through killing a few people. "No more speed i'm almost there... gota keep cool now gotta take care"

    An old man told me one time, you will go down that hill and around that curve too slow every time, but you'll only do it once too fast.:smt045

    This really isn't a fair question, as all trucks are different. What works for one won't work for another. Using the same gear to descend the grade that you climbed it with will work if you have an engine brake. If you don't go one or two lower.

    the generic info in my CDL guide says "a lower gear than you climbed the hill in" but why the heck would the other side be the SAME degree angle as the side of approach?:happy11:

    Well, that's referring to percentage of grade. For example, if you can climb a 9% grade in 6th gear, it is suggested that you descend one in 5th or lower with that amount of a load.

    I just let the tranny take me down the hill, pop it into a gear that gets me down the hill "quickly" and safely. If that means dropping it 5 gears so be it. Better then brakes fading out, then no way to stop in an emergency.

    This would be for the 10 speeds out there...I was also told take your 10 deduct the grade % and that = your gear to be in 10-6=4th gear. I always just followed the one gear lower then you climbed with and then used slight and steady pressure on the brake all the way down the mountain, never had any issues, other then Supertruckers cussing at me on the CB cuz they want to go faster down the mountain and when they come around a corner and I am sittin there blowing bubbles at 25mph, it just upsets them. What I like about CB's though, is the off switch...
