- What Every Trucker Should Know About Engine Braking (AKA the Jake Brake!)
Every truck driver should know how to best utilize their truck's engine brake. In this video, we talk about what the jake brake is, how it works and most importantly, best use of the Jake Brake.
The Jake Brake is one of the most underused safety tools of the professional truck driver. Many new truckers as well as some of the more experienced drivers, don’t know the potential of this tool and how to use it to get the best results.
There are 3 positions to the Jake Brake settings:
Position 1 - Lowest braking power
Position 2 - Moderate braking power
Position 3 - Strongest braking power
The Jake Brake can be used in adverse weather and road conditions, but with adjustments, caution and common sense.
Never use the Jake on ice. No truck driver should be operating on an icy road.
In slippery conditions, it can be utilized with caution, depending on the weight in the trailer, terrain etc.
A Lower Position can be adequate to add to ‘braking’ power.
It can be an invaluable tool, if used correctly, and if the Jacob’s Brake is set up correctly (not just a lot of noise, but actually functioning correctly).

The sound of the Jake brake is comforting, reassuring me that I won't smoke the pads and over speed.
True man 👍
Agreed.
Amen.
Sign: No Engine Brake Use In Town
Billy Bobtail: haha jake go brrr
I alway figure that my jake is way quieter than the screaming family in a crushing car. Haha... kinda different if empty or bobtail tho
“Runaway lanes are for those who use their brakes”
Only Cat/Cummins are that annoying
I always laugh: No using your safety devices while in town.
To me, the sound of the Jake brake is the sound of 50 tonnes holding speed going downhill without me touching the brakes. It is a very welcome sound in that way.
I grew up on a somewhat steep hill that trucks often traveled. I used to love hearing the Jake when though I didn't know what the sound was at the time. I Also used to crank my arm to get them to use the air horns. Those positive experiences led me to be a truck driver and now I'm 5 years into my career and working at a company that treats me well.
Very cool!
Time to get ur truck
Starting When i was 8 it was my job to flip the jake on and off for my grandfather while we were coming down steep winding grades. Looking back it was Usually because we were dodging scales haha. But even when i was 8 years old 20 years ago i knew the value and importance of the jake break
One of the greatest inventions in trucking!
I've tried multiple times to explain to drivers that the "jacobs engine retarder" doesn't actually induce differential friction force between the tire and the road surface as actual service brakes do. "Jake brakes", instead slow down engine rpm and slow down the drive shaft. It basically creates drag on the engine. It works because it counteracts momentum and the natural inertia of the truck in motion tending to want to keep rolling.
The reason service brakes are problematic on slippery roads is that they cause differential speed between the tire and the road surface. This leads to slippage and loss of traction because you've induced differential speed between the tire and the road surface that exceeds the ability of the tire to grip.
I use mine in all weather, and have never had a problem. It saves tire wear and service brake wear. I change tires every 350k miles and brakes on average of 600-700k miles, usually just to leave no "interpretation" if I get pulled for inspection.
I can't imagine how dangerous trucking was for drivers before they had all these amazing tools. You really have to respect the old timers and their experience with older equipment.
My job today is far easier and more comfortable than in their time and I'm very thankful for that fact every day on the road. The trucks of today are basically working RVs compared to the rubber block suspension bench seat trucks and COEs of the 50's through early 90's.
Jakes save on every component.
I'd say the easiest way to explain it is that Jake Brakes works by not letting the truck pick up speed in the first place by limiting engine RPM whereas normal brakes work by forcibly slowing your tires down.
Much appreciated
Off topic comment. I dont know about all you old timers and such, but I unironicly enjoy listening to "east bound and down" while running loads
They're thirsty in Atlanta, and there's beer in Texarcana....lol
It's a great trucking tune, one of the best!
As a newer driver I love the Jake breaks, they really do make things safer and helped me a lot when I was learning.
There's a trucker who lives just outside of town and he snatches that Jake Brake when he passes my house. The speed limit drops from 50 to 35 and he refuses to just coast down to speed. It used to irritate me because it would wake up my sons. But now they're grown up I don't care. It's like "brrrrrapapapaapapap oh...there's Roy. He's home early this week."
I laughed out loud when he said Cajon Pass, I've had 2 trucks break down there 1 going up, and 1 going down from Hesperia. Oh the joys of trucking! Stay safe everyone, enjoy the ride!
Good stuff, thank you for watching!
The best time to use your jakes is in a truck stop parking lot at 2:00 am.
Edit:I'm being sarcastic if you can't tell.
Tell that to CR England! Between the Jake and the damned Refer, they make sure EVERYBODY knows they are there.
and then start a regen next to the guy sleeping!
Made me laugh right out loud Bradley!
Some idiots have done it for real unfortunately 🙄
Lmao
Just so you 'SUPER TRUCKERS' know, some of us company drivers operate 2020 models that activate the brake lights when the Jake is being used. You can stop whining on the CB about us burning up our service brakes. we are actually aware of the stupidity of the function and apologize for it.
I always get a chuckle when some dumb dumb comes on the radio to natter at another driver for this, these systems have been out for years and they still aren't aware of it.
It's not stupid. Keeps the guy behind you from rear-ending you if he can't tell you're slowing down
I love how a crucial safety device gets banned because it’s loud, like Jake brakes and train horns, locomotives use something similar it’s a dynamic brake and it draws power from the traction motors and transfers it into excess heat that gets vented, doesn’t sound nearly as cool, just kinda sounds like a jet engine
Ironic that firearm silencers are taxed because they muffle.
I’ve driven for 8 years now and have used jakes from the moment I started driving 😂😂😂 I use mine 90% of the time lol I absolutely hate it when I get into a truck and the Jake doesn’t work for Jack! It’s an absolute must for me. Good video!
Thanks for watching! The jake is a must have for me as well.
I use it all the time, especially when I'm going through Portland 😁
I use mine 90% of the time. Even when pulling an empty flat and especially on wet roads. It helps to avoid locking the trailer tires when there's no weight on them.
Far safer and no wear. When I have had to touch my brakes in the rain I have had nasty surprises, a wet brake drum grabs different and it can veer unexpectedly..
I work for a big LTL carrier and I run between Sacramento and Reno every day. Even though we mostly have newer automatic Freightliner Cascadia tractors, the engine brakes work really well on them. I can do the whole run over the hill, and barely have to touch the brakes with the transmission locked in 9th or 10th gear going down the hills especially coming westbound off Blue Canyon and down the 3-mile coming into Colfax
idk about any other, but my truck school straight ignored the Jake. I taught myself at my first job
My trainer said of the Jake Brake. Just roll your window down stick your head out and go "Burrrrrrrrrrrr" youll slow down just as fast.
Hint. That does not work. Ha.
@@jerrykinnin7941 your trainer has zero clue
Bryan I learned as a kid, I'm 2nd gen but didn't get my CDL until I was in my late 30s after the Army. My instructors were fans of the Jake and taught us when to use them.
I watched a runaway truck coming down the Bakersfield side of the Grapevine…. It was about 57-59 and they were in the airborn, passenger hanging out of the window, waving his arms wildly and screaming. My grandpa saw it in the mirror and told me to watch… it was both terrifying and exciting.
Thankfully about 7-10 miles after the road flattened out… they were pulled off to the side of the road and were shaken but fine
I saw a sign in Du Quoin, Illinois. It said something like "please do not engine brake unless required for emergencies." I respect that a whole of a lot more.
Yup, nothing wrong with that!
i see that a lot in small rural towns in wisconsin
If you have an emergency the jake brake is the last thing you are going to use the jake has no emergency use
I see the sign allot that says. "Use of unmuffled Exhaust brakes illegal."
That makes sense.
Between the Jake brake and dropping gears, I didn’t need use my brakes all that much.
Great video, Dave. Thanks
Yup, good gear selection and jakes can handle pretty much any load hill combo.
Jakes use more fuel tho.
@@nitemareman1 jakes dont use fuel your right foot does
@@michaellee5399 lol... thats funny.
In the 90's when I was a snot nosed kid the truck I was running did not have Jake brakes. I was going across Meachum one morning and I stopped and picked up an old timer who had tagged a deer and cracked his radiator. I pulled off into the brake check area to check my brakes before going down Cabbage. The look on his face was priceless when he found out I did not have Jakes. In the few minutes it took to check my brakes that old timer had got on my CB and had another trucker stopping to take him down the hill. It's a good life.
That's funny!
I would probably get out too and find someone with jakes 😂
i currently live about 20 to 30 miles west of meacham, cabbage and deadman passs small world!
I drove otr for just over two years where I learned about using the Jake Brake on many mountain passes. I made the change to being a local driver and went into the concrete business driving mixer trucks. I have been fortunate enough to get trucks that did have a Jake on them, and that was very reassuring, not to mention safer. I have talked to people that say that having a Jake on mixers is a waste, and I beg to differ. I think that it really depends on the region you are operating in. I am currently driving a truck without one (as many newer trucks do not have them, being deemed as non-essential, and an extra expense). The only way to alleviate problems is to drive much slower on approaching grades. I hate to admit it, there have been times that I had to really get into the brakes, and the smell is not pleasant and kind of embarrassing when you get to the job site (not to mention the wear and tear on your equipment). You are taught to have a sense of urgency having a perishable/live load, you just have to use really good judgment on when to be urgent and safe at the same time. It is also really good to have excellent directions, and have good knowledge of the route. I find it interesting how companies push safety, safety, safety, then hold back on the tools that would make you a more safe driver.
I think it’s less about safety, safety, safety, and more about money, money, money, with as little liability as possible.
Yeah, too cheap to practice what they preach. They should be embarrassed.
If memory serves me right, the older mixers, such as mid-seventies on down, weren't ever equipped with anything other than service (and parking) brakes. There was a PTO type system that turned the drum instead of hydraulic used on newer equipment. Point is, manufacturer's weren't comfortable with the weight of a full drum having a direct connection to the motor on top of the normal braking demands of the GVW. Don't take this as gospel, it's been 25 years since I've been around mud trucks and I probably remember some information incorrectly. Ask around to see if this sounds familiar. I may need a refresher course haha!
I use to live in a small town where the main road was on roughly an 18%-20% grade and at the bottom there was a decently busy railroad crossing. There is a no engine braking sign but I don’t think any of us ever judged a trucker for doing his best not to slam into the side of a train. I remember my brother and I climbing out the window and sitting on the porch roof watching the trucks go by. We would try and get them to blast the horn or listen to the jakes thunder down the hill.
@@erikmeyer5207 some backroads have very steep grades , the biggest I’ve seen is 12% in Pennsylvania and I’ve only been otr for a year.
@@KangX92 In the "PA Wilds" aka The Allegheny National Forest or over by the Pocono's? I've been down BootJack Summit in the ANF many times.
@@erikmeyer5207 there’s a road sign that says 18% I’m not kidding
This man is on point with his info. I am from Jamaica with very steep hills
I ride a freight shaker, that jake brake has been my friend my first day behind the wheel. Hell even my adaptive cruise control which uses the jake brake on its own was like my second trainer when I went solo for the first time.
Wonderful. Lesson learned. I've always believed once the vehicle is straight you won't have problem with the Jake.
My Jake saved my life on a icy downhill road in pa it was the only thing to slow me down
Love your vids. " her cuuter shakes when she hears them jakes" lol.
From my CDL instructor... "The jake is a tool, not a toy."
Good quote! He's right!
My impact wrench is a tool but I still love playing with it.
I was getting ready to say in not one video none of you guys show you actually pressing the engine brakes and what they look like to a new person like myself that's never used one. So thank you for being the smart guy you are and checking all your bases and providing us that information which is very useful and you used them all three back to back and made me feel comfortable in doing the same, so thank you very much.
And I always run my jakes on stage 2 .I jump to stage 3 when I am running anything over 45,000lbs and I keep the rev under 15 and I have no issues..
Thank you sir for all your videos. I read many dumb comments here, zero appreciation.
Thanks Benjamin!
I’ve been driving an automatic for 7 years. I decided it was time for a change and knew a test drive on a manual was inevitable for new employment. Thanks for the great refresher videos for the confidence I was looking for and I got the job.
I can’t even imagine driving without a jake break. Its a must have feature in any truck in my opinion.
A friend of mine uses his Jake Brake in town because we live in a giant bowl, you've probably been through my town once or twice on your forays through BC. He got fined for using it down a steep hill that has a lighted intersection right at the end, he went to court and said "this may not get the fine taken away, but I think that my full loaded logging truck's jake brake is a lot quieter going down that hill than it does slamming through your house". Not sure what came of it after that, but i'd have to agree with him
I agree with him too. He should have won that court case. I'm a bit surprised a local cop would ticket him for that!
@@SmartTrucking you might have been through my town in your forays through BC. There is a sign that says "no engine brakes $250 fine" half way down that hill but I have yet to hear one truck follow that sign, because a $250 fine is a hell of a lot cheaper than plowing through 10 cars and the intersection
That is 95% of the towns in BC (north or east) of Hope. They are at the bottom of a hill and they all have those ridiculous signs at the top of the hill that leads into them.
Glazed brakes are way noisier and more annoying to me, and way more dangerous than a Jake. People who don't drive a truck don't understand.
That cat sounds GOOD
Yeah, she does, thanks!
It baffles me how some people choose to live right over a freeway and then complain about jake brakes and other truck noises.
Yup, some people's kids! Don't have two brain cells to rub together!
Those are the same kind of people that move in next to an airport then complain about planes flying over their house.
The first tractor that I bought (and still own), a Cummins powered 1995 Freightliner FLD12064, doesn't have Jakes. It never bothered me because dad an grandpa taught me how to run grades LONG before Jakes became common so, I never had a problem. Every tractor I've bought since then has had Jakes though. Like you, I normally run all 3 heads and only turn them off completely is on ice.
With all that said, how about a video on why it's important to have and know how to use a power divider a.k.a. differential lock. Even in the summer months, I see MANY drivers "stuck" in short, steep loading docks because after unloading, their rear drive axle is off the ground. I can't believe how many of them don't know they have one, let alone how/when to use it! These days, my tractors all have full lockers so when I flip that switch, all 8 have power.
Great show as always! Thanks for sharing!
The term “Jake Brake” is kinda like Kleenex for facial tissue. A “Jake Brake” is a Jacobs Vehicle Systems Compression Release Engine Brake. Clessie Cummins invented it, Jacobs made it reality.
The one other option which exists these days makes use of an exhaust brake which provides a restriction in the exhaust. They’re basically a butterfly valve installed downstream from the turbocharger.
From a mechanic standpoint - thank God you’re here to explain this stuff to people! The day you and those like you retire I will have a much harder job.
Fun fact the Cummins doesn’t use a Jacobs brake anymore and they haven’t for years. It’s called a C-Brake and has been at least since the N-14s, same principles of operation apply.
Mack had that Renault engine and they called their brake a “power leash” - same operation.
A true Jacobs brake is easy to find on old alpine green Detroits.
I got one in my green leaker.
I am a huge fan of the “jake brake”! They work great for speed control and management. In all kinds of weather. Sometimes you adjust how and when you use them for traffic and road conditions, but overall they make for a better, safer operating and driving environment. I am also a fan for using them in combination with cruise control. With the modern computer controlled engines, you set your desired decent speed and let the computers adjust the settings as needed to hold speed. On the last trucks I drove, the cruise control could activate and deactivate individual cylinders. So instead of a 3 position setting jake, the cruise could choose between 6 settings. With the newer automatics, it could upshifts and down shift as needed for additional braking power adjustment to stay in the desired speed range. I enjoyed that capability and used it often. But remember, you still have to actively monitor the system, because if it shuts down or goes haywire, you speed can increase surprisingly fast. Don’t do Tesla driver autopilot stupid and become one of those drivers who didn’t pay attention and then wound up hurt or dead.
Thank you, brilliantly explained.
Great video! I love the Jake brake sound.
Thanks for the explanation. I'm grateful.
I had a co drive who always left the jakes so when ever he let off the accelerator it slowed. He never wanted to use the brakes he wanted to save them for when you where really needed. Only one time was there a issue. I was asleep in the top bunk and he almost had a wreck and the jake was on 3 in a frieghtliner and he hit the brake pedal pretty hard. Short story I was thrown into the window and had internal bleeding. I learned a lesson and so did he haha
I truly appreciate your videos. You teach me so much.
Yes sir the knowledge is unreal.
Thank you for the knowledge and wisdom.
Great Information on all of your videos
The Jake in the truck I drive is a necessity, definitely comes in handy when grossing 100k lbs. If you're ever looking for ideas for videos. I'd love to see a video on "Michigan special" trucks.
Yeah, some of those things are amazing! Thanks!
On the hardball here in Maine we get 100K. Off road 200K+ with a single truck and trailer up to half a mil running two full length log trailers
Jake brake !!!! Love that sound!!!
Very helpful. Thanks!
ONE of the best videos you have made THANK'S
Always learn something, glad I found your channel
Welcome aboard!
Hey thanks great video talking about those super truckers I seen a guy used stage 3 in the fuel island line unbelievable 🤠👍🏼
Informative as always, never heard of the brake saver.
The best truck expert...so educating
3 stage Jake brake. I use position 3 when I have a heavy load. Position 2 when hauling an MT trlr. And position 1 when Bobtailing
I think a lot of the complaints about Jake brakes and the cause for signage saying don't use them is the Lowder more extreme Jake brake applications. Most of your newer more modern trucks aren't near as loud and noticeable. I agree safety trumps your choice to live right next to a hell on the highway.
Love your videos. Thank you very much.
Thank you so much for your info, really helpful
That Cat has 3 valve covers but only one head
You're right!
It’s a good kitty cat too because it only has 1 charger on it and no ACERT junk
@@andrewkeasling1065 god acert motors suck ass in trucks
My dad said of the Accert Cat's
They painted a Silver series Detroit Yellow.
Interesting, I was using the Jake brake on my motorbike long before I'd ever heard of the term.
Fifty years ago when bikes were basic single cylinder machines and brakes were hardly adequate, I accidentally pulled the valve lifter open on my 500cc single cylinder Ariel and realised how effective it was as a brake. It gave almost infinite smooth control when used in conjunction with the throttle opening to the degree that I used it all the time. The greater the throttle opening and the better the retardation. The only thing to remember is to close the throttle before releasing the valve lifter.
Well Said. However, I disagree with your comments on the CAT Brakesaver. I drove two 359’s with them, and they worked far better than any Jakes that we had on our 3406’s at the time. I do believe those Jakes did need adjustments, but they weren’t my regular trucks. But the two B/S’s that I drove worked incredibly well. Dropping off the Grapevine n/b, I rarely had to touch the brakes. The two bad aspects of a B/S is that they are very heavy and also, you have to watch the oil temp as it will heat up very quickly. But thanks for all of the other great tips, including the common-sense approach to making noise needlessly. Come on, folks....use your heads!! You wonder why people get pissy when trucks make noise. Use your Jake coming off of a hill, not bobtailing through town....with straight pipes. Really?!?!
You'd be surprised!
Love the sound of the engine brake
Floating gears and jaking while bobtailing still sounds good to me. Especially right beside a sign that says(no Jake brakes)🤣
I'm getting the impression that you may be a bit of a trouble maker. Carry on!
@@SmartTrucking yes sir just a little 🤫
Best information video I have seen this whole month. Thanks
Thank you!
Thanks for this info ... a very good invention for trucks
Thank you for doing a segment on jakes, I've been seeing more and more drivers not using them especially in the mountains and smoking their brakes
Live the videos, just recently started watching your channel, I am starting at training academy next month so I have been trying to learn as much as I can before hand, great job, thanks
Welcome aboard!
Learned something new today!
Very informative video.
Thank you sir I’ve learned a lot from you over the years. You’re truly a great man 👨 I appreciate your patience and kindness to show us a bit of what you know. Thank you 🙏 thank you 🙏
Going thru Pennsylvania today trying to not use the jake brake in heavy rain today like my mentor said stabbing the brakes to keep the 20k lbs on my trailer going on these 5-7% grades in heavy rain was not working I would slow down but the rain was causing the trailer to slide sideways I had truck fly by I could hear there jakes on finally I gave up and turned them on level one and it made a big difference never slipped and held those hills perfect I was slowing down before a hill down to 50-55 mph just so I could coast down and brake before a corner and try and bring it down from 63-55 mph but the three second rule on stab braking was not slowing me down enough with wet brakes. Thankfully I gave up that method and went with the jake brake it worked like a charm I could even tap the throttle to keep it off and let it do it’s thing towards the start of each corner. The rig was holding the lane fine. When applying the brakes I found myself sliding a bit but the jakes didn’t slide. I will use them in rain on straights before a corner now
Great video, thanks.
Thank you Mike!
Once again I learned something from you even though I have been out here for awhile. LOL. I do always appreciate your historical perspective info!
Thanks for watching Stephanie!
Loved this explanation. Be safe.
Thanks Nancy, you too!
Great video !
Thank you!
I wished he could teach me how to drive trucks love his youtube videos great wisdom on trucking.
Great video I pull oversize-overweight I always have my jake in high
Love your channel
Thank you!
Your truck sounds amazing
Kind sir, I enjoy what you contribute to trucking culture and education. Keep on trucking, sir. Thank you.
Thank you for sharing your knowledge
My pleasure!
I appreciate this video. Thank you.
You are so welcome!
Excellent driving advice
Glad it was helpful!
There is nothing that sounds like a CAT with the Jake on 3, love it.
Me too!
Lived just off the I-215 in Salt Lake City for many years, west side not east side next to the richies. Heard Jakes every day, including fire trucks, never bothered me. Now when I was going down Parleys Canyon and wouldn’t hear a Jake and smelled brakes I always got worried.
You live in a beautiful part of the country Jack!
Excellent video on jakes! Been driving since 93 first 4 n cab over didn’t know what a jake was until 97 just knew those Pete’s on I 81 hanging those curves without hitting brakes were pros and when I grow up I’m going to be a pro too. 😂
Great info on the Jake, totally agree with Evermore. Absolutely can't stand open pipe bikes, just useless junk toys. But a truck is working making our countries go and yes, a big truck on the Jake coming down the grade sounds great to us kids at heart!
Right on!
Yes u really do great video I'm a truck driver in Jamaica on I love watching videos im driving for about twenty years on I still learn a thing r two from them
Hello Dave, I really enjoy all your videos! They are very informative. I'm a wannabe trucker. But only haul sugar beets in the fall and love every minute of it. I've been in the building trades for 34 years and love everything about heavy trucks and driving. Thank you for the content!!
Thanks for watching Jim!
Man that thing purrs!!! Awesome!!!
She's a good old truck!
Great great information........👍👍👍👍👍
Thank you sir!
Thank you got you video help me a lot yo understand the motor break I have 18 speed Peterbilt
Thank you for the video. As a new trucker this was very educational and informative.
Glad it was helpful!
I love me the sound of a good Jake brake!
I do food service and drive a 2019 freightliner but these videos still feel very comforting and provide some great info. Keep up the good work
Thanks, will do Raymond!
Great video i was looking for tips on engine breaking before my cdl exam.
