Which brake system is responsible for applying and releasing the brakes based on the driver’s input?

The service brake system is the primary brake system utilized in a vehicle, specifically designed to respond directly to the driver's command. When the driver presses the brake pedal, the service brake system engages to slow down or stop the vehicle. This system is typically hydraulic, meaning it uses fluid to transmit force from the brake pedal to the brakes themselves, facilitating effective and responsive braking according to the driver's input.

The service brake system is essential for regular driving conditions, providing the necessary control and stopping power. It operates in tandem with various braking components to ensure safety during the vehicle's operation. Other brake systems, while important for specific scenarios, do not function in the same direct and immediate way as the service brake system when it comes to everyday driving and stopping the vehicle.
