Function of vacuum booster

The function of automobile vacuum booster is to make full use of vacuum (negative pressure) to increase the force exerted on the pedal by the driver.

The vacuum booster is usually located between the brake pedal and the brake master cylinder. In order to facilitate the installation and use, it is usually combined with the master cylinder as a component. A small part of the master cylinder goes deep into the vacuum booster shell. When the vacuum booster fails or there is no vacuum in the vacuum pipeline, the push rod of the control valve will directly push the diaphragm seat and the push rod of the brake master cylinder to move through the air valve, so that the brake master cylinder will produce brake pressure, but the force acting on the pedal will increase.
