Jake brake vs trailer brake

It sounds like you're running the truck with cruise on. In the summer time, sure..winter time I only use cruise control for high idle.

 

Jake brake 99% of the time
Downhill let the jake do the job .... if thebjake cant hold the speed slowbdownn..gear dowen si yhe jake make it ....

Keep service brakes all the time cold for 100% emc brakepower

 

Jacobs is always two switches on the dash, ready to go at any time.

Again Im leery talking about using a jake at 105 kmph because that's 60 plus in American speed and it's too #### fast on most mountain grades. And the slop you referred to increasing even higher before the jake is commanded to turn on by computer tells me that the People who built it have no idea on correct Jake Brake Operations.

Again.

A mountain can be pulled in a gear. There is a commandment in trucking you run uphill in a given gear, that is also the gear you came down in Or the next lower. With Jakes it's ever more true.

Automatic cruise control have no place on a mountain downgrade. I have used them uphill to ease the pain on my right foot sometimes when the lug speed is greater than 25 mph minimum.

And there is the specialized idle for sleep operations, if you are pulling 1200, you can be assured of adequate heating in the winter time. Anything less produces cold air into the sleeper and make you sick.

Mountain work is so simple. I doubt there is much of anything else to get into besides locomotive Dynamic Braking which in and of itself is aweeesome.

 

I've always said that you can go down a hill with the tranny in the same gear that you would have to use to climb it.

 

I think that's a good rule of thumb IF you are familiar with the hill. I usually descend 1 or 2 gear lower than I climb a particular hill but I'm putting 680HP to the ground and it pulls like a beast. Gives me more climbing ability but adds nothing for descending. My thought is that service brakes are for emergencies and the Jake is for slowing down (road conditions pending).

 

680 Horses to the drives forward is very good. Awesome as far as Im concerned.

Remember with the right Jacobs Setting up to your engine, you can actually use the 680 horses against your gross load downgrade.

The goal is here to allow the jake brake to find a balance in a particular gear against the whole load downgrade at which it will operate steady and no need to touch any brake at all. That way your brakes, wheels and tires are very cold and ready for emergencies that crop up, including... using your decap bar to hold back a truck that has lost his air and is in a out of control run away mode.

I do not mention stuff like that but there have been times lives stood to be lost.

 

You're making me scared, I drive tiny mountain roads all the times, but never experienced winter before and this year will be my first!

 

We all have to learn sometime.

In my day, my instructors identified mountains with NO jake as a fear. I tried to hide it and soldier through it but nope, they had me on mountains until I got happy.

My first winter was a war. At that time we had a 1989 E Volvo Intergrated sleeper with what I recall was a 350 CAT brand new team truck. The teammate of the trainer broke a leg so went home to recuperate. I got to go with him JIT dedicated to GM of Baltimore from Kentucky to get auto glass several trips a week.

It was into the teeth of winter, there was no I68 in them days. No matter how steep or snowy it got. I did not battle ice until I took the Ford 9000 day cab and went into a icy parking lot to do a circle under control then a figure 8 as well. I was hiding from the boss while learning ice myself. I would do that regularly each winter no matter what truck I had.

Fear that makes you freeze and do nothing will get you hurt, killed or someone or many someones. Fear is something that is part of learning and mastery of a problem. It's normal. What is very strong is that you continue to function despite that fear.

 

There is a lot of good advice in this thread. Not that I plan on running mountains in the winter any time soon, but I'm glad to have read it.
