I wish I could say some more about each component that the Air brakes have, but I guess that’s topic for one of my next articles, since I need to focus here on explaining how do Air brakes work?
Why Do Trucks Use Air Brakes? How do Air Brakes Work With Trucks?
There are millions of reasons why the heavy trucks are using Air brakes, but as the most obvious I will give these two:
- Air brakes are much more practical (especially when you are repeatedly coupling and uncoupling the truck from the trailer).
- No need to bleed brake fluid of air (the fluid is air).
Sure, Air brakes have their shortcomings too, such as the more aggressive application and the initial expense, but they are definitely way better system for heavy set vehicles.
When a hydraulic system rests, there is no pressure in it. That is how they are set up; there is no braking power, until you apply pressure.
