What is hydraulic:
A hydraulic system is basically a system that use a liquid to transmit motion or pressure from one past to another. Modern brake systems are hydraulic. They use a confirmed brake fluid to transfer brake pedal pressure and motion to each of the wheel brake assemblies. Several principles apply to the operation pf a hydraulic system. These include:
- Liquids in a confirmed area will not compress.
- When pressure is applied to a closed system pressure is exerted equally in all directions.
- A hydraulic system can be used to increase or decrease force or motion.
How Hydraulic brake system action or work Hydraulic system :
Suppose two cylinders of equal diameters are placed side-by-side with a tube connection the,. the system is filled with hydraulic liquid and pistons are placed at each end of the cylinders. If you push down any one of the pistons, the other pistons will move an equal distance and with equal force.
Since the liquid will not compress and the cylinders are of the same diameter, the same amount of liquid is moved from one sylinder to others. By this action Hydraulic brakes apply in vehicle or cars.
When pistons of different sizes are used, motion and force can be increased and decreased. Suppose a small piston acts on a larger piston. The piston. The larger piston will move with more force. However it will move a shorter distance.
When a larger diameter piston acts on a smaller piston the result will be opposite. Th smaller piston slides faster in its cylinder but with less force. That is all hydraulic brakes work by hydraulic pumping system.
