What role does the Vacuum Booster Play on the Brakes?

As a Power Brake Booster Factory, share with you.

Vacuum Brake Booster Kits are the soul of the brake system. There is another key component indispensable during the entire braking process, which is the vacuum booster for the brake. The reason for this component is very simple, just because the power of pressing the brake pedal with your foot is not enough to stop a high-speed galloping car, and it needs a vacuum booster to assist it. Out, black pan-like things are.

Vacuum booster is a component that uses vacuum (negative pressure) to increase the driver's force on the pedal. The vacuum booster is usually located between the brake pedal and the brake master cylinder. For ease of installation, it is usually combined with the master cylinder into a component, and a part of the master cylinder penetrates into the vacuum booster housing.

The working principle of the vacuum booster is that there is an air chamber diaphragm partition in the vacuum booster, which divides the vacuum booster into two left and right air chambers. When not working, the left and right air chambers of the vacuum booster are connected and both are under vacuum. 

When working, the brake pedal is pushed to move the pusher to the left, and the air valve and vacuum valve on the pusher is also moved to the left. The vacuum valve stops moving after closing the left and right air passages, and the air valve continues to move to the left. Until the valve opens to fill the right air chamber with air. Due to the pressure difference between the left and right air chambers of the vacuum booster, the diaphragm of the air chamber pushes the brake master cylinder push rod through the rubber reaction disk, thereby playing the role of brake booster.

When the braking force needs to be maintained, the gap between the air valve and the vacuum valve will be reduced until the air passage is closed, so that the interior of the booster is in a balanced state to maintain the braking.

The role of the vacuum booster on the brake:

The vacuum booster is a brake servo device in the brake system of light and passenger cars. It uses the vacuum generated by the gasoline engine to work or the vacuum generated by the vacuum pump installed in the diesel engine to amplify the brake pedal force to push the master cylinder by a certain proportion. The piston causes the brake master cylinder to generate hydraulic pressure, which causes the wheel brakes to generate resistance, thereby controlling the vehicle to decelerate or brake.

The vacuum booster is generally located between the brake pedal and the brake master cylinder. For ease of installation, it is usually combined with the master cylinder into a component, and a part of the master cylinder penetrates into the vacuum booster housing.
