New trucks have exhaust brake to?
Do the newer Ford and Chevy trucks have the exhaust brake plus grade braking? I still don't like having to run the RPM's so high to bring the speed down. Sometimes up to 4,000 RPM's to get speed down and then I use the trailer brakes manually.

Can't speak for Ford, but yes, the Chevy/GMC has it (may be an option though).

You didn't ask, but Dodge has it and I love it. Wouldn't tow again without it. As you say, it makes a big difference in the mountains.

Dodge has offered the Jake brake since 2007. It's a pad & $$$ saver for sure!

According to Ford web site,
The available Power Stroke® 6.7L V8 Turbo Diesel with 6-speed TorqShift® transmission utilizes seamless engine exhaust braking and selective gearing to improve control on steep downhill grades and minimize brake wear.

Sorry to advise you but Dodge never offered the Jack Brake on the light trucks because it can’t be used on engines with hydraulic valve lifters.
It’s always been an exhaust brake.
It has been working well for Dodge on the Cummings engine but I will wait for a bit to see if anyone starts having engine heat problems with the Duramax.

I had the jake brake installed on my '06 Dodge Cummings diesel. At the time, it was a dealer installed option. Came complete with the "jake" brake emblem!!

From the Jacob's website ....
Jake Brake® is a registered trademark of Jacobs Vehicle Systems™. The term "Jake Brake" is sometimes incorrectly used to refer to compression release type engine brakes in general. The term correctly refers to all of Jacobs Vehicle Systems retarding products including Jacobs Exhaust Brakes and Jacobs Driveline Brakes as well as Jacobs Engine Brakes.

Actually Dodge started on 2007.5 truck with 6.7 CTD. My 2007 with 5.9 CTD had to have one added. I went with the air-operated PacBrake and LOVE it.

That's what I love about my 2012 F-250 Superduty - put the cruise control on 60mph and we go 60 uphill and downhill, the truck downshifts to maintain its speed.

I think most people know the Dodge is an exhaust brake but we still call it a Jake brake cause it is doing the same thing,,,slowing us down on a hill when we take our foot off the gas....

Hi
Here is a little information that may help.
Albert Champion designed the Valve Train braking system as well as spark plugs. His spark plugs were manufactured under the company names of Champion Spark Plug and AC Spark Plug.
While the history on the Jacobs Vehicle Systems web site has different story about the development of the Jacobs Brake when you look up the patent records Champion patented the mechanical system. Jacobs patented a system that was hydraulically operated in about 1961.
Champion’s story is similar to Jacobs Vehicle Systems except for the players in the near fatal event. Champion when returning from a convention where he had displayed his products for AC (about 1910)then a division of GM he experienced a brake failure on a semi-tractor trailer he was driving in the mountains. This resulted in a serious accident that both Champion and his co driver survived.
Albert Champion designed and patented the engine brake that worked by opening the exhaust valve after the compression stroke started and before the point of ignition.
The AC Corporation had no interest in this new product so Champion finally found a manufacturer to produce his engine brake. This was the Jacobs manufacturing company. They are best known for their drill chucks used on many types of products for holding drill bits.
The present Jacobs Vehicle Systems produces a full line of braking systems.
However the term “Jake Brake” is not a trademarked term but a slang term used to describe the exhaust release system designed by Albert Champion.
Chrysler never offered the “Jake Brake” on their light trucks. The emblem used on the Dodge trucks is a green squiggly road with the name Jacobs below it and this system is an exhaust system that restricts the flow of exhaust from the engine. The early Cummings engines with exhaust brakes experienced engine overheating.
Unfortunately because of the noise the original systems made the exhaust release system has been outlawed for use in many states.
You see the signs on the side of the road prohibiting the use of the “Jake Brake”. These are beginning to change because of the objections of the Jacobs Company and they now say “use of exhaust brake prohibited”. This is still incorrect because the exhaust brake doesn’t make noise like the compression release brake.

So how is it that Jacobs can make this claim on their website ... "Jake Brake® is a registered trademark of Jacobs Vehicle Systems™"?
All semantics aside, I think generally when people (perhaps other than professional truckers) refer to engine or exhaust or other forms of braking under the hood and use the term "Jake Brake", we understand what they're talking about.

Hi
I did this research for an attorney in Texas a few years back and Jacobs may well have registered that in order to try and reduce the number of government agency’s using the term for engine brakes in general on road signs. They are now using “Exhaust Brake” which is still incorrect. It should be posted as an engine brake.
By the way the attorney prevailed because the term was not a registered trade mark at that time.

Still not sure of what PhilP is talking about. Here is a picture of the emblem that was installed when I took retail delivery of my 2006 Dodge 2500 5.9 diesel. It was a Jacobs brand "Jake Brake" as you can see on the photo. BTW, you engaged it by pulling a black knob mounted on the shift lever.

In any event, the engine brake on my Cummins sure saves brake pads & $$$! A marvelous little invention for us RV haulers for sure.

The OP was talking about GM trucks and their new "Exhaust Brake". Not sure this is the same thing as the Cummins "Jake Brake"?? I have a new GMC Duramax and I have this button on my console and I would like some with experience with this product to also share their thoughts...

Hi
The engine brakes being used on the light trucks (lees than 23,000lbs GVW) are exhaust brakes.
Like I said before Cummings was the early user of the exhaust brake and they initially had overheating problems with them. For this reason I am waiting a couple of years to see how the Duramax does using the exhaust brake.
