I believe that the main reason why the Air brake equipped vehicles stop better, is because they have drum brakes, which have more surface area than disc brakes. And we all know that more friction area equals better brakes!
So basically Air brakes and their advantages only come into play on heavy vehicles. At least that is what I believe, and most people will agree with me I am sure!
Why do Cars Only Have Hydraulic Brakes?
It is hard to tell, but wouldn’t they stop quicker with Air brakes?
Well, yes, you are probably right for thinking this. Especially if you take in consideration the hydraulic fluid in the car braking systems, which can run out in the event of a leak!
And here we go again, disc vs. drum, the ongoing debate since the don of time!
Most cars have 4 wheel disc brakes despite being problematic and prone to warping. Since modern disc brakes can lock up all wheels (without using ABS), there is no chance to make them stop better.
