Which component in a high-pressure hydraulic system helps decrease brake pressure?

• A. Brake controller
• B. Debooster cylinder
• C. Pressure sensor
• D. Fluid reservoir

Answer: (B)

The correct answer is the debooster cylinder because its primary function is to reduce brake pressure in high-pressure hydraulic systems. When a pilot applies the brakes, the debooster cylinder simultaneously receives hydraulic pressure and mechanically reduces the force applied to the brakes. This is particularly advantageous, as it provides appropriate braking force without overwhelming the system or causing excessive wear on the components. The brake controller, while integral to managing brake application, does not specifically work to decrease brake pressure. It primarily regulates the overall braking system's performance rather than altering the pressure itself. The pressure sensor measures hydraulic pressure within the system but does not actively modify or decrease that pressure. Similarly, the fluid reservoir serves to store hydraulic fluid necessary for maintaining system pressure, but it does not engage in pressure modulation directly.
