Key Takeaways:

Multiple aircraft incidents involved brake system failures, with the master cylinder consistently identified as the root cause.
Master cylinder issues ranged from manufacturing defects (stuck valves, metal shavings) and internal damage (sheared piston rods, faulty seals) to general wear.
These failures led to serious consequences such as loss of directional control during taxi or landing, runway excursions, and propeller strikes.
