What is the main purpose of a hydraulic system in brakes?

The main purpose of a hydraulic system in brakes is to amplify brake force. Hydraulic brake systems utilize fluid mechanics to increase the force applied by the driver on the brake pedal. When the brake pedal is pressed, it creates pressure in the brake fluid, which then transmits this pressure to the brake components at each wheel. This allows a relatively small amount of force applied to the pedal to be converted into a much larger force applied to the brake pads or shoes, enabling effective braking.

By using hydraulic principles, the system efficiently transfers the force, ensuring that the brakes can stop the vehicle effectively with less physical effort from the driver. This is crucial for vehicle safety and performance, as it ensures that the brakes engage smoothly and provide the necessary stopping power even under heavy loads or high speeds.
