That's my opinion and I'm stick'n to it. :)
Does your truck have an exhaust brake?
No it doesn't. But the one I'm ordering this year will.
My opinion (and it's only an opinion) stands. It's based on what I've learned through reading about light duty truck EB's.
My gas engine has pretty effective compression braking. I don't advocate using compression braking (downshifting) every time you want to slow down either even if it does make brake pads last longer.
You can do what you want with your truck. I always turn on EB and TH after starting the truck. Service MGR at Dave smith Motors suggested I do so all the time. Head West coast Chrysler Warranty person says to do so.
Fact is line pressures are higher in TH and it keeps your engine rpm's up and trans in the proper gear for the speed you are driving. When driving thru town without TH and you apply the go pedal and you are in 6th you are adding stress to your torque converter. Keeping EB on with TH makes the Service brakes last longer. Turbo stays working better.Cummins12V98 wrote:

Laziness or stupidity. It provides zero benefit with no load and zero benefit on level ground or on uphill sections and the benefit going downhill depends on the load and the grade. Only an idiot would leave it on all the time when it is only going to provide a benefit 1% of the time.
On a 5% or greater downgrade that goes for miles and with a tow load of more than 4,000 lbs. the exhaust brake does help to keep the speed of the rig down with little or no use of the brakes (tow vehicle or trailer).
Clearly they need a truck manual for dummies.
I guess I am a "dummy" !!!
My truck components will outlast yours because I am a "dummy".Sport45 wrote:

On new trucks it moves the impellers on the turbo to create the back pressure. If you don't use it often enough they get clogged up with carbon and eventually stick.
I have head this as well but believe it to be a myth...
Just watching my turbo vane position in my Edge CTS without the exhaust brake on its all over the place based on output demand. Its not like without the EB on its not ever going fully open or close.
One negative aspect of using around town is that you have to remember your BRAKE LIGHTS do not come on when the EB engages. So if you have it set aggressively and someone is tailing you just be prepared.
Not really different than downshifting with a manual transmission!- Hopefully all this wisdom of stupidity and uselessness for using an exhaust brake is coming from those who actually have one. Otherwise.....your words of insight are worthless.
