Using the correct type of brake fluid in air brake systems is crucial because it prevents deterioration of seals, which are integral to the overall functioning and safety of the braking system. Different types of brake fluids have varying chemical compositions, and using an incompatible fluid can lead to chemical reactions that cause seals to swell, harden, or degrade. This deterioration can result in leaks, loss of braking efficiency, and potential brake failure.

Each type of brake fluid is formulated to maintain specific properties, such as viscosity and boiling point, which can affect the performance of the brakes under different conditions. Maintaining the integrity of the seals ensures that the brake system operates effectively, providing reliable and consistent braking performance, which is vital for safety.

While other considerations such as braking response, compatibility with brake lines, and legal requirements are important, the preservation of seals directly impacts the longevity and reliability of the braking system, making it paramount to use the appropriate brake fluid.
