Its primary role is to amplify the force the driver exerts on the brake pedal, reducing the effort needed for braking while improving the efficiency of brake response. lts core principle relies on the pressure difference between vacuum pressure and atmospheric pressure to generate auxliary thrust. This thrust works with the driver's input to push the brake master cylinder, building hydraulic pressure that ultimately enables wheel brakingSpecification:Color: BlackMaterial: SteelBrake Booster Diaphragm Style: DualMaster Cylinder Stud Thread Size: M x 10 x 1.5Package Contents: 1 Power Brake Booster Note: This product is intended for replacement use.

• Function: The main function of the vacuum brake booster is to amplify the force applied by the driver to the brake pedal, reducing the effort required for braking and improving the efficiency of the braking response
• Reliable Design: The vacuum power brake booster is primarily composed of mechanical components, including a diaphragm, vacuum valve, atmospheric valve, and push rod. It has no complex electronic components, which contributes to its reliability
• Features: The vacuum brake booster directly utilizes the natural vacuum from the engine's intake system, without consuming additional fuel or electricity
