AdvantagesSimple in construction.The hydraulic brake system works on the principle of Pascal’s law, i.e. it applies equal pressure everywhere in the circuit.Provides an increased braking effort.Self-lubricated system.More flexible linkages.Provides mechanical advantages without long and heavy levers.
Environmentally Friendly Hydraulic Fluids

The design of hydraulic systems is complex and outside the scope of this chapter. However, a brief overview is provided here for necessary perspective. Hydraulic systems convert mechanical power into hydraulic pressure via the fluid. Pascal’s law applies to hydraulic fluids since they are non-compressible media in confined spaces; hydraulic systems are designed to magnify forces so that the force generated is greater than the load, thereby permitting work to be performed. This contrasts with pneumatic systems, which involve air (which is compressible) as the transmitting media. The size of a hydraulic system is therefore proportional to the power output needed. The volume of the hydraulic oil needed in the sump and the equipment weight increase in greater power systems. See Table 42.2.

According to Pascal’s law, pressure exerted on a confined fluid will act in all directions with equal force. Pressure = Force Area or Force = Pressure × Area

Using a fluid to transmit loads can present several advantages, comparing to other solutions. Pascal’s law, on hydraulics, defines that a pressure increase in a point of a confined fluid is transmitted for any other point, without losses. So, reducing crossing sections of the fluid is possible to amplify loads. In pavement energy harvesting, that type of system has a big potential, because the mechanical energy can be amplified, increasing the conversion efficiency.
