• Brake booster pump is an important part of automobile braking system, which aims to help drivers apply braking force more easily.
• Principle of vacuum booster pump: Based on the vacuum produced by the engine intake manifold, the force exerted by the driver on the brake pedal is amplified by the pressure difference on both sides of the diaphragm. When the driver steps on the brake pedal, the diaphragm inside the vacuum booster pump moves, changing the pressure difference and boosting braking.
• Vacuum booster pump is mainly composed of shell, diaphragm, push rod, check valve and so on. The shell is divided into a front part and a back part, and the middle part is separated by a diaphragm to form two chambers.
• The vacuum booster pump is generally installed in the engine compartment, close to the brake master cylinder and the firewall, and connected with the engine intake manifold through a vacuum tube.
• Significantly reduce the driver's stepping on the brake pedal, making the braking operation easier, especially in emergency braking or frequent braking.
