Hydraulic systems play an important role in mechanical engineering. Various projects can be designed which employ the principle of hydraulic systems which is transmitting the force applied at one point to the second point using means of an incompressible liquid. Hydraulic brake is one such project designed using the principle of hydraulic system. The property which differentiates hydraulic brakes from normal brakes is that it helps to stop easily when vehicle is moving at a speed. These brakes are first choice of professionals and bikers. The components that make up hydraulic brake are master cylinder, lines, fluid, slave cylinder, pads, rotor etc. the advantages of hydraulic brakes are that there are less rates of tear, the construction of these brakes is very simple and also the hydraulic brakes offer high mechanical advantage. When you are thinking about a topic for your project at graduation level, then you can consider the project of designing a hydraulic brake. It will help you know the theoretical concepts of the hydraulic systems and the construction will help you know the whole design of the hydraulic brake.
