What are common signs of hydraulic system failure?

Unusual noises and fluid leaks are clear indicators of hydraulic system failure. When a hydraulic system is functioning properly, it typically operates smoothly and quietly; any unexpected sounds, such as grinding or whining, can signal mechanical issues or component wear. Fluid leaks further confirm problems within the system, as they indicate a loss of hydraulic fluid that is essential for maintaining pressure and ensuring proper operation. The presence of such leaks can lead to a drop in system performance and efficiency, potentially resulting in costly damage or complete system failure if not addressed promptly.

High efficiency and smooth operation, a low pressure alongside excessive fluid, or a clear and steady flow are all characteristics of a well-functioning hydraulic system, not indicators of failure.
