If a brake system fails due to lack of fluid, is the lack of fluid a basic, primary, or secondary event in a fault tree analysis?

It could be primary, however, usually, it would be secondary, the primary failure being a ruptured hose or O ring.

Thanks!

You're welcome! If you have any more questions or need further clarification, feel free to ask.

You're welcome! In a fault tree analysis, the lack of fluid in a brake system would typically be considered a secondary event. This is because the primary failure that leads to the lack of fluid is often caused by factors like a ruptured hose or O-ring. The lack of fluid itself is the result of the primary failure.

You're welcome! In a fault tree analysis, the lack of fluid in a brake system can typically be considered a secondary event. A fault tree analysis is a systematic approach used to identify and analyze the potential causes of system failures.

In this case, the lack of fluid would usually be preceded by a primary failure, such as a ruptured hose or O-ring. These primary failures would be the initial events that lead to the secondary event of the lack of fluid in the brake system.

To further clarify, a fault tree starts with a top-level event or system failure and then breaks it down into contributing causes or events. The primary events are the direct causes or failures that lead to the top-level event, while the secondary events are the consequences or results of these primary events.

In summary, while the lack of fluid itself may directly affect the performance of the brake system, it is often considered a secondary event in a fault tree analysis. The primary events, such as a hose rupture or O-ring failure, are the root causes that contribute to the lack of fluid in the system.
