Air Brake Relay - How it Works. Air braking systems and Commercial vehicles

A more detailed look at the air braking system, in particular with this video at the air brake relay.
Relays are fitted to an air braking system for larger vehicles to speed up the application and release of the brakes, minimising brake lag, which is the time it takes between the driver operating the controls (park brake/foot brake valve) and the action actually happening at the brakes.

This is the clearest explanation and visualization of air brake systems that I've ever encountered. Thank you!

[@EducationalMechanics]

You're very welcome, thanks for watching.

[@5wh1]

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!

[@vincesmith5846]

Yes! Very good video!! Thanks

[@c.a.mcneil7599]

Thank you for this great video. You must have spent a lot of your valuable time making it.

[@VivekAnandJ]

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!

[@EducationalMechanics]

I love Eddie Izzard!

[@Kevin-ip8uf]

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

[@EducationalMechanics]

Thanks Kevin 😀

[@TheSuperKnug]

Im soooo happy that ive found you! You could not beleve how much easier my studies are now! Thanks again!

[@Gary-ld6ht]

Very good explanation-you made it very simple and easy to understand

Thanks BirdDog, glad it helps.

[@mr_nice.]

Finaly, a video about air brakes that can be understood by everyone!

[@colerobison6916]

This is EXACTLY the information I was looking for. Thank you!

[@tankosl]

Great video!!!!The simple graphics make the principles much easier to understand.....thank you very much!

[@EducationalMechanics]

Thanks Mark. It means a lot to us.

[@r0ckworthy]

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!

[@GunawanWidihardjo]

Thank you, this video is very helpful for brake system analysis

[@patodwyer721]

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

[@zues2013]

Short concise and informative. Thank you

Great job

[@sam111880]

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 :)

[@truckcaretv8649]

Good 👍

[@Kami-dz3pc]

You are brilliant

[@harjindermaan8891]

Thanks for video

[@edmourgagnon1504]

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!

[@charlieabbot3649]

Well done.

[@ovidiofs1]

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 .....
