Introduction to Trucking - Air Brake Chambers

Answering a fan's question with a video is better than answering it in 500 characters or less. *LOL*

This video describes the newer Maxi-Chamber design, which you'll find on almost every air-brake vehicle today. The older design, a "Roto-Chamber" design, may still be found on antiques. For a view of the Roto-Chamber components refer to the image below;

I'm glad I watched this video. Everything just clicked on how it's a dual system that uses the same controls. Even though my instructor had explained it and showed us a brake chamber I still didn't get it but now it all makes sense. So both the emergency brakes(spring brakes) and the service brakes use the same brake drums and lining but they're only applied when you hit the brake pedal because your putting air into the service brake system. The spring brakes are held back by 60 PSI

@MarioAldanaJumuzna Exactly, that's why when you loose air your emergency brakes lock up the tires.

Hello is a Brake chamber and Maxi chamber the same

[viperzeroone]

Good question! A Maxi-Chamber is simply a term for the newer style of spring break chamber. The older design, which you may still find on antique air-brake vehicles, was called the Roto-Chamber. The Roto-Chamber was basically a can that contained the components, it wasn't actually separated into two brake chambers like the Maxi-Chamber is. I've included a link in the description for this video, should you wish to see a Roto-Chamber design. Once again, great question!

Very good, thanks

I remember this primitive system well and that's why I don't long for it at all. The basic elements are the same as brake chambers, an air dryer, anti freeze systems etc.

Electronically controlled brakes help in many ways, ie. the 8th axle's brakes at a trailer bite at the same time as the steering axle's ones, no lag between 'em. ECB make possible brake blending between brakes and auxiliary brakes as the motor brake and retarder, they're disc brakes of course , The ABS is mandatory in modulars

This was a helpful video I learned so much about the air brake system.

I can't hear it

@tetanus1234 When you release a brake you are actually adding air to the front chamber, which pulls the pads away from the drum and allows the wheels to turn freely.
