Hydraulic systems such as a vehicle’s brake system, are systems that operate, moves or are affected by a fluid. Depending on the system, the fluid may be water-based or oil-based.
Hydraulic fluid is a medium that transmits power in a hydraulic system. The viscosity, wear protection, oxidation stability and foaming resistance are typical factors that determines the type of hydraulic fluid. The viscosity of the fluid must match the operating temperature of the hydraulic system.
