I don't know how to thank you, sir! You nailed this extraordinary air brake relay video down to the science. Excellent devery style and methods to my mind's taste buds. I was blind about this concept, but you made me see! Once again, thank you and may God bless you!
Very clear and understanding video. First year Apprentice trying to understand all the fundamentals in the heavy diesel mechanic world and videos like this help alot. Thanks
I'm a mobile 24 hour diesel mechanic here in Michigan America....I've watched one video and I'm already hooked.... already subscribed on to the next videos lol....thanks keep up the great work my English brother....Britain and America... boyfriend girlfriend FOREVER lol
Awesome video! Now I feel like I completely understand air brake relays, and this is extra helpful because I now know I have a faulty relay on my school bus. Cheers mate!
I love this kind of straight forward video and they really takes a lot of theory and time to do this kind of video! Thank you SOOOOOOO SOOOO MUCH! Have you moved on in life and so never upload since 4yrs ago? :P Wish u good life and happiness in whatever you are doing
Thank you so much for this video! Very well explained. I just discovered your channel and am looking forward to watching more of your educational videos!
Wooooo. Slow down mate. Easy to see that you know your stuff. But remember... good teachers speak slowly enough so that everyone will understand. This is not a race... 10/10 for the graphics!
very nice video cleared up the lag issues i was concerned about in air brakes as well as where the sound is coming from when air is released out the exhaust port when you let off the brake pedal as well as the brake button/throttle's on dash. Its this simple relay component that i over looked. The relay is an important components :)
I've been driving trucks for 15 years. I had a feeling there were relays used but i didn't know how they work. Now i know. I just uploaded a video show how air brakes work.
One misconception people have about airbrakes is that "Air presure" activates the brakes. As a matter of fact, it is the other way round. By default, the beakes in an airbrake system are already activated without airpresure. Cos the brake actuator is actually powered by a set of very powerful springs. So when you start your engine, airpresure build up to the desired guage and when you release the parking brakes, air presure goes into the actuator and releases the brakes. and that's when you can move the vehicle. Now, what happens when you apply the service brake, is that you are releasing air presure from the actuator which in turn allows the springs to activate the brakes.
I’m sorry, but that’s incorrect. You are right that the parking/emergency brake is applied by spring pressure and held off by air pressure. That’s why it is called a “spring brake.” But the service brakes work the other way: they are held off by springs and applied by air pressure. Loss of air pressure will stop the vehicle because of the parking brakes, but air pressure is needed to operate the service brakes. There is a good series of videos by Bendix about this. Railroad trains apply air pressure down the brake line to release the brakes (and charge a reservoir on each car), and they reduce the brake line pressure to apply brakes.
Its a pretty good video i know for dumies it would be nice to explain how is the air going from the supoly through the bolt/inlet valve into the brake delivery
Let it be noted that air brakes are designed to fail safe. IE if NO air is available ( burst hose) the spring will apply the brakes. There is also the dead man's brake. That is a brake that can apply brakes to the trailer only if it is Jackknifing. Usually fitted to specialist vehicles such as recovery trucks.
This is the clearest explanation and visualization of air brake systems that I've ever encountered. Thank you!
You're very welcome, thanks for watching.

lol, I'm an instrument tech looking for information on pneumatic relays and this was the best video I could find to explain it. well done
Thanks Kevin 😀
I'm about to start the journey of studying every one of your videos.
Thank you for this great video. You must have spent a lot of your valuable time making it.
This was just awesome! I LOVED the "tu tu du..." part. Reminded me of one of the most epic stand up comedians I know, Eddie Izzard!
I love Eddie Izzard!
Im soooo happy that ive found you! You could not beleve how much easier my studies are now! Thanks again!
Very good explanation-you made it very simple and easy to understand
Finaly, a video about air brakes that can be understood by everyone!
Great video really clarified how it works over what books tell you
This is EXACTLY the information I was looking for. Thank you!
Short concise and informative. Thank you
Thanks for taking the time to put this together. Great explanation, graphics are a big help.
Thanks BirdDog, glad it helps.
Great video!!!!The simple graphics make the principles much easier to understand.....thank you very much!
Thanks Mark. It means a lot to us.
You're sooo good at explaining, keep it up
thanks 😄
What's even more marvellous is the durability of these parts.
Awesome video! Now I feel like I completely understand air brake relays, and this is extra helpful because I now know I have a faulty relay on my school bus. Cheers mate!
Thanks a lot for the good teaching, I love this, very easy to understand
Very well explained, can be understood by everyone

Have you moved on in life and so never upload since 4yrs ago? :P
Wish u good life and happiness in whatever you are doing
Hi. I’m still here. I’ve got a few more videos to make. I’m just really busy teaching. Thank you for your kind words. :-)
Thank you so much for this video! Very well explained. I just discovered your channel and am looking forward to watching more of your educational videos!
Fantastic explanation and illustration. Great video!
Thanks. 😉
Excellent video. Relay just acts like a diaphram control valve.
Excellent work. Keep it up.
Thanks Abid Mahmood. 😀
That was easily understood, thank you.
This satisfies my curiosity of that air below vehicle blown on the road. Exhaust... Air released from delivery pipe line.
Thank you.
Fantastic Video. Thank you so much
Very nicely explained & the sound you make in between daa daaa makes me laugh. Keep it up. Thanks for the video.
Namaste
2:29 made my day
Wooooo.
Slow down mate.
Easy to see that you know your stuff.
But remember... good teachers speak slowly enough so that everyone will understand.
This is not a race...
10/10 for the graphics!
I passed my test yesterday but yet here I am still doing refreshers 😂
Very well explained. Thank you.
wow , you explained it in so nice way , i can do better tomorrow in my exam, thankyou
Thanks Shubham Mishra, good luck tomorrow.
Thank you sir , i've watched lots of your videos that would be very helpful , thanx a lot
Outstanding explanation. Graphics are awesome. Thank you for posting
Thanks for a thorough explanation
Great video, very informative.
For a small valve, there's a lot going on there. I'll have to look at this video a few times to take it all in. Thanks
Superb explanation. Someday (if you like) would love to see a similar video for DD3 (bus, non-spring brake) brake systems. Thanks.
Good 👍
This guy is legit! Very educational and it made me laugh!🤣🤣😂😂👍🤘
Thanks Willie B. 😘

Great video. Just subscribed!
I was just working on one of those relays last week. Really threw me for a loop I think now I can fix it
Good stuff. Just like been a DAF training school but without felt tipped pens and no nodding off lol
Still got my red, yellow and blue felt tips! 😉
Thanks for explaining the functioning of RV in a simple way...
You're welcome. We're glad it helped.😀
Brilliant video, cannot thank you enough!
If I put another axle with brakes , I have to take the same signal from the pedal and putting one tank of air obiusly, great video .....
Finally, I got it.
Thanks to your video
Happy Thanksgiving day
Well Done Private One.🙂
om a truck mechanic so am loving this video
Thanks for sharing this video sir
Thank you for watching. It means a lot to us.
Thanks for the information, very well presented😀😀😀😀😀😀
Excellent. Greetings from Venezuela.
Спасибо , за видео очень информативно и полезно!
Now what is difference between relay valve and quick release valve.
Fantastic video we need more
Well done!
Interesting. I’ve never seen a hand control valve of that style for the spring brake release before, just dash mounted popoff valves here in NA.
Thank you, this video is very helpful for brake system analysis
I have a 2017 Frieghtliner Cascadia and the Air Dryer is located right in front of the passenger tire off the chasis, very easy to get at !!!
Who cares
Thank You Sir, Great Observed Good Idea Video Channel I love this post to learn more about
Good video and clear to understand mate
Thanks Muchie
Very very good
excellent video
NICE e explanation, THANKS😃😃
VERY WELL DONE VIDEO !!!!!!!!!
Thanks Robert

Thanks.
blackericdenice do you know why some air brakes squeak when releasing the pedal ?
Would like to get into it, tips ?
Thanks for the great vidio sr.it help me alot
Thanks for Teaching And God Bless

Best among available...
Nice channel mate
ON THE TEST QUESTIONS, DOES 2000 FLATBED TRUCK REQUIRED THIRD OR TOP BRAKE LAMP ASSEMBLY
You are brilliant
Good job.
Great video but where does the exhaust hose(yellow) from the parking brakes goes to?
Super clear!
Thank you for sharing. very good video.God bless you.
Thanks Alex.
amazing...explain ❤
Thanks for video
