The switch says exhaust brake but that probably doesn't mean anything. It seems to work fine but I'm just not used to it being that way. Will this system hold as good down the mountain passes? Anything I need to know about these? By the way it is a Spartan chassis.
Any help is great..

It's a exhaust brake (butterfly valve hooked up after turbo) not a compression brake (jake). That's why you don't hear all the noise of a jake brake. Yes it will help in descending grades, but not as good as a compression brake. The higher you keep the rpm's the better it will hold.
