A vacuum booster, also known as a brake booster or vacuum servo, is a critical component in modern automotive braking systems. It amplifies the force applied by the driver on the brake pedal, enabling safer and more efficient stopping power with minimal physical effort. The device utilizes engine vacuum (or an electric vacuum pump in hybrid/EVs) to create a pressure differential across a diaphragm, which in turn multiplies the input force. This technology is standard in passenger cars, light trucks, and heavy-duty vehicles, directly influencing braking safety and driver comfort.

The global vacuum booster market is driven by increasing vehicle production, stringent safety regulations (e.g., FMVSS 135 in the US, ECE R13 in Europe), and the shift toward advanced driver-assistance systems (ADAS) that require precise brake actuation. As automotive electrification grows, electric vacuum boosters (EVBs) are gaining traction, offering independent vacuum generation for start-stop systems and electric vehicles.
