Vacuum booster

The vacuum booster is an important part of the brake system, and the vacuum booster is a larger diameter chamber. Inside, there is a diaphragm (or piston) with a push rod in the middle. The cavity is divided into two parts, one part is connected to the atmosphere, and the other part is connected to the engine intake pipe through a pipe. The vacuum booster utilizes the principle of inhaling air during operation of the engine, causing a vacuum on one side of the booster and a pressure difference from the normal air pressure on the other side, and utilizing this pressure difference to enhance the brake thrust.
