Arby49 - As you can see from the responses, there is no answer for "when and how" the engine brake should be deployed. Main thing is to play with it and see what works best for you.

Personally, I use it only when I want it to help me slow down.. :-) Otherwise it is slowing me down every time I take my foot off the accelerator, and I prefer to coast at will without the brake kicking in.

I don't hold engine brake on for more than 30 seconds anyway just my thing from old days driving truck as internals can get hot from too long on the brake.
well your very wrong and you may as well not even bother in my opinion
for 30 seconds
I go down long mountain passes for miles on stage 2 at 60MPH and works just fine

As a former PacBrake engine brake and exhaust brake distributor (20 years, installations, sales, service) I see many miss-understandings on the use and operation of an engine brake or an exhaust brake listed above.... and I know I'd start a riot if I started to teach the correct method....


A trip to either PacBrake, or Jacobs, web site... and find the model of your brake and see for your self how it functions and the correct operation... and use of your brake... if you have an engine brake there is usually a metal tag on the riser on the engine block with a tag with the information you need.... if you have an exhaust brake there will be a metal tag on the housing that supports the air cylinder...

I personally use mine 100% of the time.... I allow the computer on the engine/transmission to correctly lock up the torque converter, and down shift as needed... most of you with a transmission temperature gauge, a lower than normal temperature unless you have some transmission slippage... and lower engine temperature....

BOTH PacBrake and Jacobs work with the engineers at the engine factories to build a brake that performs and complies with the engine engineering needs...

Hope this helps..

Thank you for the input. I appreciate all the information I have received from this post. Now as soon as my rig gets out of the hospital, I plan to give it a shake down run.

Select55 - maybe I didn't say it properly. I leave the brake on for 30 seconds take it off for 10 or 15 then re-apply but I am way under 60mph so can control speed with brakes while Jake is off, then repeat the cycle. You are correct in saying applying it once is no good. Each of us have our methods, but if we all get down every hill safe then we are all winners.
