How do you know if your exhaust brake is working?
It seems my exhaust brake is not stopping the coach as much as it used to. The transmission will still downshift & rpm goes up upon activation of the exhaust brake button, does this mean the exhaust brake is really working too? how to tell if exhaust brake mechanism is really working too?

Cummins ISC 360 8.3 engine
My exhaust brake switch is attached to the Gear shift just below the knob (6 sod. manual). There is a little red light on the switch, if the EB is on the light is on, if off, the no red on. I can also get the truck up to about 60mph, then turn the EB off, you should feel like your are coasting with little resistance. When you turn the EB on you should feel the truck slowing down as if you were going head on to a fairly strong wind. When my EB is on, the sound of the exhaust from the engine is louder and with a rumbling like sound. At that speed, I can turn the EB on and off there is a an obvious different feeling and sound.
