There are several types of brake boosters used in cars, including:

Vacuum Booster:

Working principle: The vacuum booster utilizes the vacuum from the engine’s intake manifold to generate assistance. When the driver presses the brake pedal, the vacuum force in the booster pushes the internal piston. This force is then transmitted to the master cylinder through a linkage, increasing the brake system pressure and providing additional braking force.

Hydraulic Booster:

Working principle: The hydraulic booster relies on hydraulic pressure to provide braking assistance. It consists of a pump that supplies hydraulic pressure, a booster unit, and control valves. When the driver presses the brake pedal, the control valve in the hydraulic booster opens, allowing fluid to flow from the pump into an auxiliary chamber of the booster unit. The pressure of the fluid pushes the piston inside the booster, increasing the brake system pressure and providing additional braking force.

Electric Booster:

Working principle: The electric booster uses an electronic control system to provide brake assistance. It includes an electronic control unit, sensors, and an electric booster unit. When the driver presses the brake pedal, sensors detect the pedal force and transmit the signal to the electronic control unit. The electronic control unit calculates the required assistance based on the signal and provides the corresponding brake assistance through the electric booster unit.

These brake boosters work by utilizing external forces (vacuum, hydraulic pressure, or electric power) to enhance the force applied by the driver on the brake pedal, thereby providing stronger braking performance. They are designed to make braking easier, quicker, and more efficient, ultimately improving driving safety.
