What is a
power brake booster? In case you don't know, this is one of the most important
parts of your vehicle. While driving, when you apply the brakes of your
vehicle, you feel a pressure. This pressure is generated by the brake booster.
On the other hand, if you don't feel the pressure, know that the device is not
doing its job in an efficient manner. In this case, what you need to do is get
it fixed or replaced. Let's read about some tips that can help you buy one.
How do they work?
The brake
booster starts its job as soon as you hit the pedal to reduce the speed of your
vehicle. If you open up this device, you will see two chambers divided by a
strong diaphragm. When you hit the gas pedal, the chambers become free of air.
What happens is that the system sucks all the air out based on how hard you hit
the brakes. The higher the pressure, the higher the amount of air that is
sucked out of the chamber.
How to buy one?
If you are
interested in buying this device for your car, know that they come in two
types: hydraulic and vacuum. If you are a beginner and have no idea about which
one is good for you, we suggest that you follow the tips given below. They will
make it easier for you to choose the best device to meet your needs.
Hydraulic
These
devices can be seen working in engines that are fueled by diesel and comprise a
steering pump. This pump is full of a hydraulic fluid that is put in an
accumulator.
As soon as
you put pressure on the pedal, air pressure gets released. This process
generates a tremendous amount of pressure, which can be as high as 2,000 psi.
However, there is a disadvantage of this system. This system cuts down on the
horsepower as it makes use of a good deal of electric power to work optimally.
Vacuum
Another type
of brake booster is known as the vacuum power brake booster. When you step on
the brake pedal, the air inside the diaphragm is forced out. As a result, your
vehicle slows down to prevent a possible crash or accident. So, they can be a
great choice for your vehicle, especially if you own a large vehicle for
commercial purposes.
The biggest
benefit of using a vacuum power brake booster is that if the engine of your
vehicle stalls, you can still use the brakes. However, in this case, you will
have to push with more force. You may want to ensure that your units are tested
for vacuum for reliability.
So, these
are two types of power brake boosters for a vehicle. If you are going to buy
one, make sure you know the type of device your vehicle needs. If you have no
idea about it, you can consult an expert. Lastly, if you want to maintain your
vehicle, make sure you keep the power brake booster in the best condition.
