Why is a liquid (the hydraulic fluid) used to operate the brakes in a car ?
According to Pascal's law the pressure remains constant at all the points in the fluid which is at rest.The car brake's consists of a master cylinder filled with liquid oil and provided with airtight frictionless piston.The master cylinder is connected to wheel cylinder by a tube.The wheel cylinder is having two pistons connected to brake shoes. the similar system is connected to all the wheels.when the brake pedal is pressed the lever is pressed the piston of the cylinder is pushed inwards.There will be increased pressure on liquid which is transmitted equally to pistons of the wheel cylinder due to which pistons move outwards which in turn press against the rim of the wheel & hence retard the wheel.
