What is the function of the service brake?

The service brake's primary function is to slow down or stop the vehicle during normal driving conditions. This braking system is designed to provide effective deceleration and control while traveling on roads, allowing the driver to respond to traffic signals, stop for pedestrians, or reduce speed when necessary.

Service brakes are integral to vehicle safety, as they need to be responsive under varying conditions, such as wet or slippery roads. Their operation is essential for maintaining safe driving speeds and ensuring the vehicle can stop in a controlled manner, which helps prevent accidents.

Although parking brakes and other systems assist in specific scenarios or conditions, they do not replace the fundamental role of the service brake, which is critical for everyday driving situations.
