What is one purpose of a brake debooster?

The purpose of a brake debooster is to increase the volume of fluid going to the brakes, which is crucial for optimizing the brake system's performance. In many aircraft brake systems, especially those that use hydraulic actuation, the debooster is designed to convert higher pressure, lower flow hydraulic inputs into lower pressure, higher flow outputs. This allows for better modulation and responsiveness of the braking system, ultimately leading to more effective braking actions during various phases of flight, such as landing or slowing down on a runway.

By ensuring that a larger volume of fluid reaches the brake actuators, the debooster can help maintain the necessary braking force without overwhelming the system with pressure, which could lead to brake lock-up or inconsistent braking performance. This balanced flow characteristic is vital for ensuring safety and control in aircraft operations.
