Dual-Air Brake System: All You Need About To Understand

what is dual air brake system

Dual Air Brake System is an additional type of air braking. While each of the following air brake systems uses its own connections, pneumatic cylinders, and cables, they all have a typical array of brake settings.

This sort of air brake system shares one circuit. It utilizes simultaneous braking or combines loops into one, while each method allows its systems. This braking system applies one brake to the front hub and the second to the rear hub.

This braking mechanism dates back to around 1971 and is still prevalent today. This type of braking system undergoes frequent modifications due to ongoing modifications. It also results in an ongoing rise in usage.

What Underlies The Dual Air Brake System’s Fundamental Concept?

According to the friction theory, a Dual Air Brake System uses two loops. If one loop has a problem, the other loop will function.

The air is pulled from the main reservoir through the heel lever and transmitted to the relaying lever. It happens when the car’s brakes are engaged.

It sends air from the main reservoir to the brake pedal cylinders. The air is pulled from the auxiliary reservoir through the heel cylinder and transferred to the front brake cavity simultaneously.

What Purposes Do Dual Air Brake Systems Serve?

The dual air brake mechanism promotes safe and reliable driver tunability when all brakes fail. If any car’s brake pads have a problem, the idea is to prevent complete brake problems.

The secondary system will keep working autonomously, preserving the car’s braking capacity. Even if the essential brakes malfunction for any purpose or if the system has an air leak. A heavy tractor can be stopped securely by the operator.

What Characteristics Do Dual-Air Brake Systems Have?

  • The Dual Air Brake System separates the other loop if one loop ceases operating due to a malfunction. In this situation, the other pathways continue to operate as intended.
  • The functioning fluid in a Dual Air Brake System could never run out. In contrast, many other brakes are more at risk of fluid leakage.

What are the Drawbacks of Dual Air Brake Systems?

  • A pressure regulator is required to assure that the pressure in the primary and secondary tanks is comparable. If not, the brakes will not work correctly.
  • Typically, Dual Air Brake Systems are more expensive. Air brake units generate moisture from compressing the air, which has to be dried with an aspirator. The expense of upkeep goes up as a result.

How Do Dual Air Brake Systems Impact Automobiles?

Nowadays, most automobiles with air brakes have a Dual Air Brake System. Multiple distinct kinds of cars have this kind of brake. In particular, big vehicles use this kind of system.

Several auto manufacturers employ dual brakes at the moment. Dual brake systems are more frequently used. Today, all heavy-duty trucks must have dual-circuit braking systems as a legal obligation.

How Can I Tell Whether My Car Has Dual Air Brakes?

The air pressure gauges positioned on display, which are typically labeled “primary” and “secondary,” are the fundamental sensory indicators that a driver has a car that has a dual-circuit brake system.

A singular indicator with two sticks shows the pressure in the first and second systems. It is more common in cars than in two distinct meters.

All cars with air brakes will have at minimum one air pressure indicator positioned on the cockpit. So it may check while the car is moving.

How To Begin Dual Brake System?

The oxygen concentrator needs time while moving to build up within the first and second sections using Dual Air Brake. Before moving the car, both systems’ pressures should reach a minimum of 100 psi.

Why Consider Dual Air Brake System Pressures To Reach 100 Psi?

The primary and secondary cylinders’ air pressure must reach at least 100 psi before the air brake mechanism activates.

This pressure needs to be greater than 60 psi. If it is 60 psi, the activation air brake system becomes complicated. The equipment’s warning must activate once the automobile starts to drop.

Low Air Pressure And Measurement Cautions

Pressure indicators and low-pressure alert systems are within the first and second loops. When the air pressure in the cylinder falls below 60 psi, it indicates that one of those air systems is under pressure, so either the front or the back is not working correctly.

The pressure in one or both channels is negligible for regular brake operation. Usually, a red alert indicator will activate, and a loud beep will sound. Both of these alert systems are standard on most automobiles.

When the air pressure, including both circuits, reaches the appropriate level, low air pressure alert indicators and siren turn off. The manufacturer’s recommendations typically determine this and consistently exceed 60 psi which is 414 kPa.

When To Cease, Turn Up,  And Park Securely?

If the alarm signals start to sound while you are moving, come to a halt as soon as possible. Carry it to a stand, and park it securely.

Only proceed to drive if you’ve determined the reason for the air depletion and why the alarm gadgets lit up. If you cannot be sure the brake system is secure, don’t continue to travel.

Bottom Line

The brakes of a big truck are among the most crucial parts of that vehicle. It is because of riders that haul numerous thousands of pounds of cargo.

Air brakes make up the braking mechanism in large diesel lorries, coaches, and commercial vehicles.

Large cars rely on dual air-powered brakes because they have been created to avert complete braking breakdowns. It provides greater control by enabling the truck to stop in a secure area.

Understanding the importance of Dual Air Brake Systems for regular maintenance and the safety of your vehicle is essential.
