Question

Two general types of vacuum assisted power brakes are:

Answer 1

Hint: In this question, we will first understand the basics of power assisted brakes. Also, we will study about the working of these brakes. This will help us to get the required result. At last we will discuss the basics of power for our better understanding.

Complete answer:
As we know, power-assisted brakes are also known as power brakes. The power-assisted brakes are designed to use the power of the engine and battery to increase the braking power. To reduce the driver’s pedal effort, power assisted brakes can use hydraulic, vacuum, air pressure or gearbox-drive assistance.
Further, when we do in detail, the atmospheric suspended brake booster has normal air pressure on both sides of the diaphragm when the pedal brake is released. Now, when the brakes are applied, a vacuum is formed in one side of the booster. So, atmospheric pressure then pushes on and moves the diaphragm.
In a vacuum suspended unit, when the brakes are kept on, the piston and diaphragm has atmospheric pressure on both sides of it.
Therefore, now we can say that atmospheric power brakes and vacuum suspended power brake are two classifications of vacuum assisted power brakes.

Additional information:
As we know, most of the power brake systems use the difference between atmospheric pressure and intake manifold vacuum to develop the additional force, which is required to apply the brakes. When the operator or the human depresses the brake pedal, the power booster increases the amount of pressure applied to the piston within the master cylinder without the operator having to greatly increase brake pedal pressure.
We should also know about the power. It is the amount of energy transferred or converted per unit time. In the International System or S.I Unit of power is the watt. The S.I unit of power can also be written as one joule

Note:
Here, we should remember that the power brakes systems are designed to reduce the effort while stopping or holding a vehicle. Also, a power assisted brake can use hydraulic, vacuum, air pressure or gearbox-drive assistance as well.
