What is the purpose of the storage tanks in an air brake system?

The purpose of the storage tanks in an air brake system is to hold compressed air. In an air brake system, these tanks, often referred to as air reservoirs, are crucial for maintaining a consistent supply of high-pressure air, which is essential for operating the braking mechanism effectively. When the driver applies the brakes, air is released from these storage tanks to activate the brake chambers, which then engage the brakes. This system allows for rapid engagement and disengagement of the brakes, ensuring optimal performance and safety.

The presence of these tanks enables the brakes to function correctly under various conditions by storing additional air that can be used as needed, especially when frequent braking occurs. This is vital for heavy trucks and buses that rely on air brake systems, as they require significant air pressure to achieve the necessary braking force.
