hey guys, i was just wondering what you guys do when going down steep hills. this is my biggest fear. is it possible for the engine to over rev? or do i keep"snubbing" the brakes throughout the whole descend to prevent it from reving so high? i just have the big fear of over heating the brakes. i use my brakes very minimal to begin with. now i know to use the jakes, but even with them on, the engine revs quit high.
over reving

Get in the lowest gear you think you will need before starting down hill. With proper training you can downshift, if needed.
-
Exactly what the person before me said!
-
This all would depend on the engine you have.. Detroit's usually have the higher rev limit, Cat being just a little lower, Cummins a little lower then both and Volvo or Mercedes I just don't have the drive time with in order to give you proper information about.
Possible? yes
If snubbing is done proper you would have no issue in applying the breaks a few seconds longer in order to slow and downshift..
A few post that I have posted in and also contains a lot of good information from other members.
Here is my last post on this subject when it was asked here

Use the brakes. It's what it's there for. As long as you've gone down one gear than what you used to climb up, you should be okay.
-
The rule of thumb nowadays seems to be down two - what with the newer trucks having a bit more power than the older ones. Obviously, 'tis going to depend on your truck.

I guess you've tried that going through Eisenhower westbound I-70 too, right?
It might work some of the time. But it won't work most of the time. Especially in the western grades inside reduced/restricted speed zones.
Rule of thumb here. Get low enough for the jake to hold it. The actual brakes are for emergencies, or slowing enough to drop a gear.
I want cool brake pads, in the event of an emergency. -
LOL - I LOVE that stretch of highway. Was happy as a clam coming down - eastbound. Until the *()^#$()^#$ instructor flipped off th' Jake and said - "Now drive".
No problem. Never got above 35 until I hit C470. -
Was you empty? Or did you have a load? Heavy or light? Big diff.
While I learned to drive without a jake (we didn't have em period) It's not something I do by choice. -
light load. in keeping with the new PTDI standards, the truck had 15,274 pounds in the trailer.
Yeah - I know. If I'd had a heavy load it would have been a lot more interesting. The other guys in my class thought the weight was more than enough, though. Every one of them was either gray or shaking when he got back from the mountain trip.
