Most people do not understand how air brakes work. They think if you lose the air you lose the brakes. When in fact the opposite is true. You lose the air and the brakes lock up. I have lost count at the number of times I have seen movies where the air is lost and they have a run-a-way with no brakes.

I am already very familiar with the air braking systems on trains, being a train nut, and while knowing that air brakes on commercial road vehicles must work in a similar manner, I did not know the functional differences. I also did not realize there can be a delay between pressing the brake pedal, and the brakes being applied.

From what I can gather, air brakes work in a sort of opposite way to hydraulic brakes. In hydraulic brakes, you need fluid to compress the pads against the discs, but in lorries, you're sort of taking air away, allowing the brakes to 'unlock' and compress against the rotor, so if you have no air, the brakes stay 'unlocked'. Does that sound about right?

@vasiliymedvedev1532 Ай бұрын

So when you engage, the handbrake air is pumped into a chamber in the brakes, releasing them. When the brake pedal is pressed is the air released from the handbrake chamber? or more air is pumped into an opposite to the handbrake air chamber (working against the handbrake) and engages the brake and then when foot pedal is released the air from this second air chamber is released make the brakes free?

@dhxl 4 жыл бұрын

Hmm...Still don't get how the amount of brake torque is regulated? The more you press the brake pedal the more you get air input to the brake chamber. But? But! Let's say we have infinite amount of time and the brake pedal is 1% pressed. Versus. The same conditions but brake pedal is 100% pressed. So will we have the same brake torque at some point with the difference that 100% pressed brake pedal will generate that max brake torque much faster, while 1% pressed pedal will take considerable time to generate that max brake torque?

@EducationalMechanics 4 жыл бұрын

Hi Igor. I'll try and help. The driver's brake pedal is a proportional valve, so if the pedal is pressed down 1% it will only deliver 1% of the total pressure. The pressure will not climb. With the brake pedal (the foot control valve) pressed down 1%, the foot control valve would hold at 1% and the air would make it's way to the brake chambers to apply 1% brake torque/force. If the driver pressed the brake pedal at 50%, this would apply the brake force at 50% and so on. It's why the majority of valves have a "HOLD" position, to maintain a pressure/force. I hope that helps and welcome anyone else who can explain it a bit better. Thanks.

The high pitch air expell.....is it from the gap in the slack adjuster??? I'm no rookie but I'm just curious lol

@GuerillaManifesto 7 жыл бұрын

So for the parking brake, you're essentially forcing air into the chamber to compress the discs? And the same for standard braking, you're forcing air to compress the discs? And when you let off the pedal (or release the parking brake) you're letting the air out of the chamber?

@kristupasantanavicius9093 4 жыл бұрын

Yes, but its the reverse. The actual braking is done with a powerful mechanical spring. When there is no air in the system, the spring is engaged and pushing hard on the brakes. When the truck is started, air pressure pushes back against the brake spring, releasing the brakes. When you push on the pedal, air pressure is relieved from the spring, and in turn the spring pushes on the brakes again. This means that if for some air pressure drops, the truck will automatically stop until air pressure is built up again.

as i understand. the parking brake is powered by large springs, when the parking brake is released, air pressure overcomes the springs and releases the parking brake. Im brand new on the subject but heres a simple overview of how things go. kzfaq.info/get/bejne/e9KGrLx8rMu5YZs.html
