What is Brake
Brakes are
generally used to halt the rotating wheels of a vehicle. It is used to retard
the velocity of the wheel. In hydraulic braking system pascal’s law of pressure
is used. According to pascal’s law the pressure in the system remains constant.
For that reason, the ratio of force to area is needed to remain constant.
Suppose that F1 and A1 are the force and area of the brake respectively. So,
Simple Principle of Braking System
When the
brake pedal of the car or any other vehicle is pressed the force is magnified
as the braking oil flows through the pipes. This magnified force is then
applied in the braking pads. These pads hold the hub of the rotating wheels
like a clamp. And because of the friction generated between hub and the brake
pads the wheel comes to a stop. This is hydraulic braking system explained in a
very simple way. For a better visualization have a look at the video which
describes how the hydraulic brakes work and how the bleeding of the hydraulic
break is done.
Bleeding of
the hydraulic brakes is the process with which the trapped air in the braking
system is removed. It is done occasionally to remove the trapped air when
hydraulic brakes are not working properly or not giving proper efficiency.
What is a
clutch? Working Principle of clutches
Clutch is a component used to
disengage gears while driving. Clutch is found in the gearbox close to
transmission. The important component of the friction clutch is the flywheel
which is attached with
the engine with help of crank shaft. The clutch pressure plate is attached with
the flywheel. This plate is connected to the gear box by another shaft.
And there is a diaphragm spring on the plate in front of which a clutch
release bearing is situated. When this bearing is pushed inwards the spring also
deflects and the power generated in the engine is transferred to the gear box.
