Why are the brake servos fitted to most modern car?

Brake servos, or brake boosters, are fitted to most modern cars to enhance braking efficiency and reduce the driver's effort required to engage the brakes. By using vacuum or hydraulic pressure, these devices amplify the force applied to the brake pedal, allowing for quicker and more responsive stops. This is especially important in emergency situations, where rapid deceleration is crucial for safety. Additionally, brake servos contribute to overall driving comfort by making braking feel smoother and less strenuous.
