Which of the following is a typical sign of hydraulic system leakage?

Explanation:
Leaks in a hydraulic system show up as fluid escaping and a drop in system pressure. When seals or hoses fail, fluid leaks to the environment, often leaving wet spots, and the pump can’t maintain the same pressure, so the hydraulic pressure falls. That combination—visible leaks plus decreased pressure—is the clearest, most direct sign that a leak is occurring. Increased motor power, higher ambient humidity, or faster startup don’t reflect a leak in the same way and are not reliable indicators of this issue.
