How hydraulic disc brakes work? What is it's mechanism? Answer fast it's urgent
Dear Student,
Hydraulic brakes work on the principle of Pascal's law. Any pressure applied on the liquid is transmitted uniformly in all directions and with same magnitude and is constant.
Pressure = F/A = constant
Now, if a large pressure is channelled through a small cross-section, the force applied will be very large, as the pressure is same.
Hence by applying smaller force, by a lever, pressure is channelled through small cross-section area, a large force is generated which stops a vehicle easily. This is how a hydraulic brake works. Have a look at the given figure for better understanding:
