Air Brakes - Principles of Operation 

These old Army videos are just awesome :)

this video is too deadly!!! explains things perfecly for young simple minded, non mechanicly inclined suburbanite potheads like myself. thnk u so much for posting!! very helpfull

Thanks for putting up, informative simple and clear!

THIS WAS VERY HELPFULL IN MY UNDERSTANDING OF HOW AIR BRAKE WORK, YES IT IS SOMEWHATE DATED, BUT I BELIEVE THE PRINCIPALS ARE THE SAME, THANKS AGAIN.

Good video. Would have appreciated more if it started by explaining why brake fluid system of brakes found in smaller vehicles was not brake system of choice for these heavy vehicles and can not be used here.

Great video, really cleared things up, adding park brakes and anti compound valves would be great too!

best airbrake tutorial ive seen so far!

that was a great explanation. I'm taking my air brake test next week and this helped me understand the reading material I just read!:D

This video is awesome I use in in my brakes class easy to understand can see all the parts moving and working

wow i learned both how compressors and air brakes work in just 10 minutes!!! years of research.

This video is superb. Excellent.

This video is great and easy to understand. Thanks US Army.

Thank you🙏🙏🙏🙏🙏

Congrulations to US Army... Now, I really understand how air brake system is operating... Thanks.

This video is great, it helps me a lot.

old but gold.

well my trainer said study your airbrakes and this helped alot

The US army does it right! Damn fine learning material.

You are both right! He was correct at that time, and you are correct today.

thats some good info!!! 5 stars

thanks aloooot man it helped me alot with my project you rockzzz

ESTA MUY INTERESANTE EL VIDEO AUQUE ES ALGO VIEJITO, ES EL MISMO PRINCIPIO DE SISTEMA DE FRENOS DE AIRE, GRACIAS POR COMPARTILO CON TODSS LOS USUARIOS DE ESTA PAGINA, SI TIENS MAS VIDEOS ASI SE LE AGRADESE

if I'm not mistaken, the air disc brake's rotor is made of Carbon fibre-reinforced silicon carbide as well as brake pad. TGV passenger train is using this type of brake since 1980+, used on heavy truck will gave it a passenger car like feel. air disc brake work like a disc brake on many passenger cars, but the material of the brake is different and is actuated by air pressure

in 21th centry, the air disc brake appeared, they have more stopping distance than drum air brake, same braking performance when it was heated. air drum brake on the other hand tend to stop longer distance when heated. air disc brake was used by TGV passenger train and large percentage of truck/buses in europe

check out the guy jack hammering away at 33 sec in. check out that protective gear " a hat"

i want a tv show like this

the dmv should give this on dvd for the cdl manual on airbrakes

It's good easily understood

Cool. Ah how things have changed since then.

@tomas599 The video is from 1967, that is the date at the start when it says "The United States Army Presents"

can't explain it better

Salute

It is amazing how 95% of the parts haven't changed in 40 years.

@qazwas2001 MANY parts have changed and are different. I have just taken the AirBrake course.

Except that my brakes operate on release of pressure, not by the pressure itself. If I lose pressure, my brakes are applied and I can't move. I believe that's true of all modern air brake systems.

there was no metion of the park brake release valves

that coil spring is just as big as the ones used in the suspension of a prius

@11:24, WTF that animation is cute!

@qazwas2001 oh yeah 1967 at the start, yeah your right. wow looked 50's at the lates to me anyway.

I have 2 army trailers. Both 6 ton. When the air is in the reservoir but is not connected to the tractor the trailer will not move. Its backwards from civilian trailers. Mostly because in an emergency a guy could open the valve and drain the air in the trailer tank and release the brakes. Thus pulling the trailer to a safe location or whatever the army wants. Just no brakes on the trailer when the valve is open, not safe but they don't really care about that when in a combat mode. The design i

And that is why city buses go: PSSSSSSHHHHHHH

@qazwas2001 40 years, that would make this video from 1970, this video was probley made in the late 40's

💀🖤

@qazwas2001 little more advanced, but yea pretty much the same

still don't understand

if you decide to coast downhill with the engine off or the engine suddenly dies.....you're fuuuuuucked.

looney tunes! oh wait my bad

why did i watch this?
