Mine is always on, except when it's off. Have a three stage engine brake and I usually don't need anything more than the middle setting.
It is only with the advent of the muffled engine brakes that they became pretty much silent, the old ones were very noisy and sounded somewhat like a machine gun when in use.

He may be confused. As mentioned in my previous post, he might think he has a compression brake (or "engine brake" a.k.a. Jake Brake) but actually has an exhaust brake. I'm guessing there may be quite a few that really aren't distinguishing the two.

However, perhaps he wanted to know how many drive with their exhaust brakes "on all the time and why."

Thanks for the confirmation, Steve. It sounds as if my guess was relatively accurate.

Is it a two stage or three stage engine brake and what engine is in your coach?

Almost all the time. It is great for quickly slowing for traffic or a signal change and of course it saves the brakes. Not recommended when ice or snow are present (even wet freeway) as you may have the rear end trying to pass you.

I like to coast even on exit ramps, so I only use it when going down hills or at the end of the ramp. Our ISM11 only has high and low. I use low a lot and only apply high when needed, but seldom use either in towns due to their restrictions.

The only time mine is turned off is on wet or slippery roads. Otherwise, I have it on low on a level highway, switching to high when appropriate in the mountains and high in heavy city traffic for when the idiot pulls in front of me and slows down. It only engages when the brake is touched and releases when the accelerator it tapped. With our total weight over 50,000#, the engine brake operation is very smooth in low and agressive when needed in high.

wow man are you heavy or what ;; a little slow going up the passes with that set up;; regarding the engine brake was yours set up that way from factory? I think that sounds like its smoother that way
although I like to regulate my speed downhill by turning switch on/off etc and having to hit the brake each time may be a little aggravating

I'm surprised using the engine break in rainy weather is a bad idea!!! I've spent way too much time in the mountains where a bright sunny day turns to rain in a hurry! I'd think with no engine break " Look Out Below"!

Are you actually saying an engine break is for dry road cruising only? Snow and ice I get that... But rainy roads?

FLORIDA ALLERT: No engine break - Too much rain - slippery when wet!!!

Your front end will whip around to the front? Hey have we entered Disney World? Oh... April Fools the day before Christmas... I get it!!!

Our coach comes in at 40,500 loaded and our enclosed trailer is near 12,000#. Our sons Mountain Aire with trailer is close to 60,000# Define slow going up the mountains. About 37 mph on the steepest part of I-70 west of Denver. a perfect speed to look at the scenery. I switch from low to high as needed when going down the other side using the brakes only when needed to maintain a safe speed. I have had the control modules reprogramed for several things I wanted different from factory settings, but I think the EB was programmed that way from factory. I had the previous two coaches programmed that way too.
