Dual-Air Brake System: All You Need About To Understand
Dual Air Brake System is a supplementary type of air brakes. Although each of the following air brake systems uses its own connections, pneumatic cylinders and cables, they all have a typical set of brake settings.
This kind of air brake system shares one circuit. It uses simultaneous braking or combines loops into one while each method allows its systems. This braking system brakes one brake on the front hub and the second on the rear hub.
This braking mechanism dates from around 1971 and is still common. This type of braking system undergoes frequent modifications due to continuous modifications. It also results in a continuous increase in usage.
What underlies the fundamental concept of the dual air brake system?
According to friction theory, a Dual Air Brake System uses two loops. If one loop has a problem, the other loop will work.
The air is drawn from the main reservoir via the bead lever and transferred to the distribution lever. It happens when the brakes of the car are on.
It sends air from the main reservoir to the brake pedal cylinders. The air is drawn from the auxiliary reservoir by the heel cylinder and simultaneously transferred to the front brake cavity.
What purposes do dual air brake systems serve?
The dual air brake mechanism promotes safe and reliable driver alignment when all brakes fail. If a car’s brake pads have a problem, the goal is to prevent complete brake failure.
The secondary system continues to operate autonomously, preserving the vehicle’s braking power. Even if the essential brakes are not working properly for some reason or the system has an air leak. A heavy tractor can be stopped safely by the driver.
What features do Dual-Air braking systems have?
- The Dual Air Brake System separates the other loop if one loop fails due to a fault. In this situation, the other paths continue to work as intended.
- The working fluid in a Dual Air Brake System can never run out. Many other brakes, on the other hand, are more at risk of fluid leaks.
What are the disadvantages of dual air brake systems?
- A pressure regulator is required to ensure that the pressure in the primary and secondary tanks is comparable. If not, the brakes will not work properly.
- Typically, dual air brake systems are more expensive. Air brake units generate moisture by compressing the air, which must be dried with an aspirator. This increases maintenance costs.
How Do Dual Air Braking Systems Affect Cars?
Today most cars with air brakes have a Dual Air Brake System. Several different types of cars have these types of brakes. Large vehicles in particular use this type of system.
Several car manufacturers currently use dual brakes. Dual braking systems are more commonly used. Today, all heavy trucks are required by law to have dual-circuit braking systems.
How do I know if my car has dual air brakes?
The air pressure gauges placed on the display, which are usually labeled “primary” and “secondary”, are the basic sensory indicators that a driver has a car with a dual-circuit braking system.
A single indicator with two sticks shows the pressure in the first and second system. It is more common in cars than in two different gauges.
All cars with air brakes have at least one air pressure indicator on the cockpit. So it can monitor while the car is driving.
How to start with a dual braking system?
The oxygen concentrator takes time to build up in the first and second sections while moving using Dual Air Brake. Before moving the car, the pressure of both systems must be at least 100 psi.
Why would you consider the pressure of the dual air brake system to reach 100 psi?
The air pressure of the primary and secondary cylinders must reach at least 100 psi before the air brake mechanism is activated.
This pressure should be above 60 psi. If it is 60 psi then the activation air brake system becomes complicated. The warning of the equipment must be activated as soon as the car starts to descend.
Low air pressure alerts and readings
Pressure indicators and low pressure warning systems are located in the first and second loops. When the air pressure in the cylinder drops below 60 psi, it indicates that one of those air systems is pressurized, so the front or rear is not working properly.
The pressure in one or both channels is negligible for normal braking operation. Usually a red warning indicator will activate and a loud beep will sound. Both warning systems are standard on most cars.
When the air pressure, including both circuits, reaches the proper level, the low air pressure warning indicators and the siren will turn off. The manufacturer’s recommendations usually dictate this and consistently exceed 60 psi, which is 414 kPa.
When to stop, show up and park safely?
If the alarms start to sound while you are moving, stop as soon as possible. Put it on a stand and park it safely.
Do not drive until you have determined the reason for the air exhaustion and why the alarm gadgets lit up. If you cannot be sure that the braking system is secure, do not continue driving.
It boils down
The brakes of a large truck are among the most crucial parts of that vehicle. It’s because of riders carrying thousands of pounds of cargo.
Air brakes are the braking mechanism in large diesel trucks, coaches and commercial vehicles.
Large cars rely on dual air-actuated brakes because they are made to prevent complete brake failure. It offers more control by allowing the truck to stop in a safe place.
Understanding the importance of Dual Air Brake Systems for regular maintenance and the safety of your vehicle is essential.
