An electric brake booster is a component used in automotive braking systems to assist in applying brake pressure. Traditional brake boosters use vacuum pressure from the engine to amplify the force applied to the brake pedal. Still, electric brake boosters use an electric motor to achieve the same effect. The electric motor in the brake booster applies extra energy to the master cylinder when the brake pedal is depressed, raising the hydraulic pressure on the brakes and facilitating a more efficient stop for the car. This can improve braking performance, especially when the driver needs to apply sudden and heavy braking force. Electric brake boosters can also provide additional features, such as regenerative braking, which captures energy during braking and stores it for later use, improving the vehicle's efficiency. Moreover, they can offer more precise control over braking force and better integration with other vehicle systems, such as stability control and autonomous driving features.
