What is the brake booster?
The brake booster is an important part of the car braking system that increases the pressure applied to the brake pedal and thus makes it possible to brake the car faster and with the least effort from the driver. This device is usually located in a container in the form of a metal can, inside which various components are used.
Symptoms of brake booster failure
The stiffness of the brake pedal
One of the multiple signs of brake booster failure is a stiff brake pedal, which may lead to an unpleasant experience for the driver. When the brake pedal becomes stiff, braking the car becomes a time-consuming and difficult activity.
The reasons for the stiffness of the brake pedal:
Reduction of air pressure in the booster: One of the main causes of the brake pedal being stiff is the reduction of air pressure in the brake booster. This can be caused by a number of reasons, including a malfunction in the brake air system or air leaks from various components.
Damage in the booster diaphragm: Diaphragm, as one of the main components of the brake booster, if it is damaged or punctured, it can reduce the performance and finally the stiffness of the brake pedal.
Smart booster valve: The smart booster valve plays an important role in regulating the air pressure, if this valve is damaged, the proper pressure will not be created to help braking, which will cause the brake pedal to be stiff.
High pedal
When the driver feels that the brake pedal suddenly rises, this may also be a sign of failure in the brake booster. This issue is usually related to problems in the brake air pressure system and requires immediate troubleshooting.
Suggestions to fix the problem:
Checking the air pressure levels: First, check the air pressure levels of the brake system to ensure that they are within the proper range.
Checking the smart valve: The booster's smart valve plays an important role in pressure regulation, so it is necessary to check and repair or replace it if needed, in parallel with checking the diaphragm and other components of the booster.
Check for air leaks: Air leaks from various parts such as pipes or connections may cause a decrease in air pressure and thus the pedal is high, so all possible points for air leaks should be checked.
The weakness of the car brake
One of the signs of failure of the brake booster is the weak braking performance of the car. When the driver feels that the car's brakes are significantly weakened and unable to brake in the best way and with the desired efficiency, this may indicate a defect in the brake booster.
The most probable causes of brake weakness: defects in the booster diaphragm: the diaphragm, as a vital part of the brake booster, if damaged or cracked, can cause a decrease in pressure and as a result brake weakness. Insufficient air pressure or air leakage: if the air pressure required for If the optimal performance of the brake booster is not provided or if it is reduced due to air leakage from the brake system, the car's brakes will be significantly weak.
The sound of the sound in the brake booster
Unusual sounds in the brake booster can also be a sign of failure or problem in this system. These sounds are usually recognized as voice abnormalities that require immediate attention and repair.
The most possible reasons for the noise in the brake booster: Defects in the valve or diaphragm system: Squealing or whining sounds can be caused by a defect in the valve or diaphragm system. These problems usually require repair or replacement of parts. Dirt or abnormal wear: The presence of dirt particles or improper wear in the brake booster can lead to unpleasant noises. Cleaning or replacing parts according to the problem causing the sound can be effective.
Brake booster components
The booster is in the form of a black metal can, but this can contains components that perform the booster's task together. These components are:
Braving Booster Body
The body of the brake booster acts as the backbone of this very vital system. This body, which appears in the form of a black metal can, is actually a compartment inside which the vital components of the brake booster are placed. The ability of this body to withstand high pressures and maintain the integrity of the internal parts, as a protective cover against external factors, has made this part one of the important elements in the brake system.
Smart Booster Brake Boost
The brake booster smart valve is one of the key components that helps to improve the performance and efficiency of the booster. By intelligently controlling the air pressure inside the booster, this valve plays an important role in adjusting the pressure and sending it to other parts. The ability to precisely adjust the pressure takes advantage of the complexity of the brake system and in this way provides the driver with an easier and more efficient brake pedal.
Diaphragm
The diaphragm is one of the basic components of the brake booster, which plays the main role in creating the necessary pressure for the brake function. This piece is responsible for transferring air pressure from outside to inside the booster. In other words, the diaphragm responds to pressure effects by changing its state, and as a result, presses the brake pedal and provides the necessary pressure for braking. Diaphragm with high precision and suitable resistance is very important in the correct operation of the brake booster.
One -way valve
The one-way valve in the brake booster system is an essential part that plays an important role in controlling the air flow and pressure inside the booster. This valve has the ability to control the air flow in one direction and thus prevents the brake pressure from the pedal to return to the opposite side. In other words, the main function of this valve is to ensure that when the brake pedal is pressed, the air flows to the booster and does not return to the pedal from the opposite side. This feature increases the efficiency and speed of the booster in creating the necessary pressure for braking.
Interface rod
The interface bar is one of the basic components In the brake booster system, it is responsible for transferring the pressure applied by the brake pedal into the booster. This rod is an important mediator between the brake pedal and the booster diaphragm, and when the pedal moves, it transfers the pressure into the booster. Since the connecting rod is exposed to a lot of pressure, it must be strong and reliable. These features ensure correct pressure transfer and high efficiency in the braking system.
Booster spring
The booster spring is one of the basic components in the car brake system, which plays a very important role in the performance of the booster. In addition to influencing the pressure and performance of the booster, this spring plays a major role in returning the booster to its original state after braking. When the driver releases the brake pedal, the booster spring as an auxiliary and support element returns the booster to the brake ready state. This spring plays a very vital role especially in continuous braking or in hard braking conditions and ensures the stability and correct operation of the brake booster even in stressful conditions.
Booster piston
The booster piston is one of the main parts of the brake booster, which is used in the process of creating the necessary pressure for braking. This piston is directly connected to the booster diaphragm and is responsible for applying pressure to the brake system. As the piston moves towards the diaphragm, the pressure created by the air inside the booster increases and helps convert this pressure into a braking force.
