What is a potential hazard of using brakes designed for lower pressure with a high-pressure system?

Using brakes designed for lower pressure in a high-pressure system can lead to brake failure due to overpressure. This is because the components of the brake system, such as the seals, lines, and pistons, are engineered to withstand specific pressure limits. When subjected to pressures beyond these limits, the structural integrity of these components may be compromised, leading to potential rupture, leakage, or complete failure of the brake system.

This situation poses a significant safety risk, as brake failure can result in a loss of control of the aircraft, leading to catastrophic outcomes. Understanding this hazard underscores the importance of matching brake components with the operational specifications of the aircraft's hydraulic system to ensure safe and reliable performance. Proper alignment of brake systems with pressure ratings is essential for maintaining both the effectiveness and safety of the braking mechanism.
