Been running into quite a few 6% and 8% grades with no warning signs not even grade signs at night, sometimes i end up coming into them a little fast because my perception at night isn't too good. Driving a 05' pete 379 with a 6nz, jake's don't work all that well. When it happens i've been dropping 10mph, going up 5, dropping 10 till i get down to the gear i need. Anyone have any other methods they use? Live in washington and haul all west coast so i imagine there are quite a few of you who run into the same situation. When i look to the good book of knowledge it says 5mph down in 3 seconds, if that doesn't work then go destroy your truck in the sand box.
Coming into a hill too fast, no warning signs

Old rule night driving, if unfamiliar with road, slow down, be prepared for the unexpected 25-35 mph curve.
Slowing down 10 mph, release gain 5, hit brakes again just heats brakes up quick.
Steady constant pressure and not be going to fast.bentstrider83, TequilaSunrise, LoneRanger and 9 others Thank this. -

They should’ve got up earlier, they expect a truck to be big and slow

Don’t let a 4 wheeler back-up behind you pressure you into a mistake that you cannot recover from.

The opposite of constant pressure
I get on the brakes and drop some speed and then off the brakes so they can cool .
the brakes should always work twice or three times to haul you down to about 10 MPH .uncleal13, supergreatguy and MACK E-6 Thank this. -
There is a saying that has never been false. You can take a hill/curve/grade too slow many times. But you can only take one too fast. ONCE. I've had other trucks bee otch at me going to slow. Don't matter. I still got to the same place in time for my loads.

It's probably happened to everyone at least once. Come over the top unaware of a steep grade ahead of you then start heading down the hill too fast with a heavy load, having trouble slowing down enough to drop a gear, and wondering if your brakes are going to outlast the downgrade. Not a good feeling.

Well, getting on brakes, then letting off the brakes, let’s air hit them, heating the pads.
This isn’t with brake fluid, which can overheat and glaze like in a pickup/car.
I’ve been done every mountain in the US, and was taught steady pressure, if you have a brake application gauge, don’t exceed 10, if you do, you’re going to fast, use slow down, slowly enough to let up some off the pedal, but not all the way.
I’m still alive and haven’t even had to think of using a runaway ramp or that “we’re all gonna die!!”
But if you really wanna know how to not smoke a brake going down a mountain, here’s the best advice, in which I was told.
So I’m quoting here, “How do you not smoke a brake on a mountain, hmm, don’t go down one.”
Now remember, worn out thin pads, heat up faster than a good thick brake pad.
And this is for going down mountains, not hills, but by slowing down 10 mph, letting off to gain 5, which 80k+ which will be seconds, then hit brakes, and repeating, you’ll soon be...
and once the brakes get that hit, they’ll glaze, so they need to be changed, they’ll heat quicker and have less stopping power.pete781693 and tscottme Thank this.
