ernest917,
As you can see and read, there's lots of opinions on why drivers do what they do. First, a JAKE or, Engine Brake, (NOT AN EXHAUST BRAKE) is NO louder than the coach would be on full acceleration. The your Engine Brake exhausts through the muffler, period! So, what ever sound level is present while accelerating, you're going to get the same noise level during Jake Braking.

Second, since there's all kinds of drivers, all kinds of rigs, towing or not towing all kinds of toads with various weights, the use and effect of these JAKE type brakes will vary, from coach to coach. Hence, lots of varied tactics.

Third, it's your coach. Drive it, use it in multiple driving circumstances and practice with your Jake brake to see just what YOU PREFER for your driving techniques. Techniques used for one person may, or may not work all that well for others.

Hi scott, I am going to venture to guess that the OP has a "Variable exhaust brake" on his engine........
Maybe the OP can confirm this?

Mine is always on now - I had mine reprogrammed by Cummins to activate when the brake pedal was depressed (or tapped) - I did not like the default programming of activating the brake when the throttle is released. What I really missed was the ability to coast and the programming change allowed for that. To deactivate the brake, you just need to touch the throttle.
I would highly recommend making this change to anyone - it allows the brake to be on all the time which is a real safety plus should there ever be the need to stop quickly. It must be reprogrammed with the Cummins software - I visited Cummins just for the change and they charged me one hour labor.

Ours is too aggressive for use in town, even when attempting to carefully modulate the throttle. So it's hills and slowing from speed, like an off ramp, for the most part here. I do use it in heavy freeway traffic, at speeds that let me avoid 2nd and 3rd gear. Those shifts, up and down, are too aggressive for me. All I can think of is the abuse the engine mounts are getting on every one of those shifts....

Mine is on in the mountains and coming off high speed roads. Otherwise it's off. I don't want the engine brake coming on every time I decide to coast. Even in mountains I turn it on selectively.

I'm glad somebody brought up the fact that there's a difference between an "engine brake" (i.e. "Jake brake" or Jacobs compression brake, etc.) and an "exhaust brake" as I know it's been talked about on this forum many times through the years but probably should be brought up again for the benefit of the newer owners who may have never owned a diesel engine before.

Difference Between Jake Brake and Exhaust Brake

Most of us probably have an exhaust brake but many of you do have a true Jacobs Brake if you have a larger engine in the more upscale coaches.

Although Jacobs also makes an exhaust brake, they are famous for their Jacobs compression release engine brake which was actually invented by Clessie Cummins.

Decades ago when I drove transit buses, we had a fleet of GMC buses referred to as "fishbowls" (a T8H-5305) which had a V8 Detroit Diesel and had from what I was told, one of the first Jake Brakes used on transit buses. It was loud and powerful. Even though it had a switch to turn it off and on, we were instructed to leave it on most of the time and to turn it off only when operating at night in residential areas as it was tremendously loud. I think the modern ones used nowadays have been quieted down quite a bit.

As for the exhaust brake on the Cummins in my motorhome and pickup truck, like others have already said, I turn it on only when I need it.

I have a two stage brake on my 08 coach and I've NEVER left my brake on all the time... My reason for asking is I recently went with a friend of mine to pick up his new-to-him pusher and listened as he was told to always drive with the brake on... When I asked why I was told it's just so much safer to do so....

I was a tad confused because I've never used mine unless I'm driving in the mountains or other place with steep grades...

It's just me I guess but I just don't see the benefit of driving with it on all the time.... Thanks for all your responses...I think I'll continue using it as I have been all these years....

I don't have an Engine Brake but do have an Exhaust Brake.

However, if I did have an Engine Brake I would NOT drive with it on ALL the time as they are very aggressive as compared to the Exhaust Brake that I am currently using. Plus they are generally 2 or 3 stage brakes whereas the Exhaust Brake is only one stage.

But, WRT Exhaust Brakes I do drive with that switch activated ALL the time.

Out of curiosity, with the jake/exhaust break on. would you stop more quickly in a "panic stop" situation?
