What is the "life span" of my exhaust brake?

I just recently purchased a 2018 Ram 2500, and I absolutely LOVE using the exhaust brake, with or without a trailer (usually without)!


I don't have to touch the brake hardly ever when going down hill, and I hate riding on the brakes (for several obvious reasons).



So, my question is, I know that it is a moving part, so what is the lifespan of my exhaust brake? Let's say I use it for 1-2 hours per week with only 5% or less of the time being activated. I assume I will need to replace it after a certain amount of time, so how long is that and if so, what will it cost me?

I can't answer your question but I'm looking forward to any other replies. We recently bought a 2018 Ram 3500 and my husband also looooves the exhaust brake. He uses it and we have not even bought a trailer yet!

It is AWESOME! I have only used it with my 24' TT and my boat, never with the 5th wheel (yet!). Works better with a trailer attached. But works great even without. I use Full Exhaust Brake, not Auto.



I have done some research on the intarwebs, and found lots of good info on how they work, how they extend (dramatically) the life of your brake pads, etc. But nothing about how long it will last and how much it will cost to repair it once it wears out.

I have operated big rig diesels for many, many years, I have never known one to fail. Have had one quit working occasionally, but it was always a sensor or accelerator pedal switch.....something electrical, not internal to the Jake itself.

I suppose it happens, but I've never seen it.

Shouldn't 'wear out'. You do have to lubricate it occasionaly though.

Your RAM 6.7L Cummins Diesel uses a variable geometry turbo (VGT). A major benefit to this turbo design is the integrated exhaust brake that utilizes an internal sliding nozzle to cause back pressure for additional braking


Best thing for that 'sliding ring' is to USE it.......not doing so can cause it to soot up/carbon up and NOT slide anymore


Turn it ON and GO. Tow/haul mode also.

Air Filter and oil changes will help life span....turbo/exhaust brake/engine

Just think, a brake works by grinding two surfaces together at high speed and high temperatures. As pointed out the engine brake works by throttling the turbo. So as long as the turbo lasts, the brake should too. Turbos do occasionally wear out I have no idea what the average life is for one

The one on my motor home is 20 years old. It's only got a couple moving parts so it should last a long time. I had a Dodge PU with one that was ten years old and worked with no issues.

Mine is a 12 with almost 200k miles and it's fine. I've used it a ton.





Here's a tip about them. if you are going down a long grade,and it's in to/haul mode with the e0brake on, the engine can potentially downshift too much over rev. If you press the accelerator just a tiny bit, it won't do that and it will stay in a more reasonable gear and do better. If it happens you'll know it. Don't panic, simply reach up and turn off the e brake and it will go right back to normal gear and you can start the process over.



Otherwise they are very good at what they do.

Many cities restrict the use of engine and exhaust brakes. I would be cautious of you don't want to be ticketed.

Sorry to nitpick, but an exhaust brake and a "jake" (engine) brake are mechanically different things. The terms are not interchangeable.
