Spring brake chamber

[@ethanbunch3274]

Currently in diesel school and my instructor was great about explaining this but something with the service brake wasnt clicking. This showed me exactly what I needed to know

[@RC-Heli835]

Nice to finally understand exactly how these work!

[@red---paulvanravenswaay2247]

Thank you for posting this. after a few times watching I think I finally understand.

[@theminihistorian781]

My grandfather invented the spring break and I have been looking for something talking about it. So thank you.

[@ugursakarya8995]

ho ho hooo. My grandfather was a Santa Claus and he died in the car accident

[@stealhty1]

Finally a video that explain it all

[@patodwyer721]

Great video, very informative.

[@randellentz836]

This video is wrong!!!!!!! During engine start up,air is not applied to the emergency side of the brakes. The only time air is Applied to the emergency side of the brakes is When the parking break button is pushed in. Yes after the engine is started, and enough air is built up, when you push that parking break button in, air is applied to the emergency side of the chamber releasing the parking brake

This is why I don't chock my tires on a hill. Once the spring brakes are on. The truck can lose all air pressure but it's not going to roll.

了解，謝謝分享！

So why spring breaks can’t stop a truck downhill when the service brakes fail ?!

[@peteranoia4570]

Brakes fail going downhill because the friction surfaces overheat. The friction material (brake shoes) glaze over, and the drums expand as temperature goes up. Glazed shoes mean less friction. Expanded drums increase stroke length, so there is less effective effort applied to the shoes (disc brakes don't have this problem). On top of that, spring breaks are about equivalent to applying 60psi to the braking effort (when the springs are fresh), instead of full reservoir pressure that service brakes can apply when you mash it.

Thank you so much

[@SpikerDragon95]

[@Dr.Fingertips]

Thank you so much!

changed my life THIS video literally CHANGED my life .. told myself I wouldn't cry booooohoooooooooooo boohoo ........... 1st comment

[@VaidasMaldzius]

so if you driving and one of your pressure hoses snap for some reason the trick will automatically lock all wheels? How it that fucking safe?

[@GachaRobloxianAndrew]

Safer than not having brake power, that's for sure. Welcome to the life of a trucker.

[@PropperNaughtyGeezer]

I thougt spring brake is vocation for college students.

[@channeltimes3548]

Air cylinder..

[@alexnavarro3567]

I had to be more specific with my search. Just “spring breaks” give you something way different

[@hekapro]

It’s spring brakes, not spring breaks :)

[@jaimevladimirsoto6110]

Está mal explicado

[@neelpatil4224]

I am a 13 year old boy and i know how to repair it

[@camdenk9730]

Ok… and?
