• 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.
• The ultra-silent air pump is made of aluminum and plastic materials, featuring a durable structure and long-term reliability.
