Hydraulic Brakes

The principle behind the hydraulic braking system is about forces applied at one point from which they are transmitted to another point by an incompressible fluid. In brakes, we call this brake fluid. The initial force which is applied to a braking pedal and then to the main piston is multiplied in the process. The amount of multiplication can be found by comparing the sizes of the pistons at either end. The pipes containing the fluid can be any size, length or shape. Pascal discovered that the pressure at a point in a fluid at rest is the same in all directions; the pressure would be the same on all planes passing through a specific point. This fact is also known as Pascal’s principle.
