What is the purpose of the emergency brake system?

The emergency brake system serves multiple important functions, primarily focused on safety. One of its key purposes is to provide a reliable means to stop the vehicle in case of brake failure. Regular brakes can occasionally fail due to a variety of mechanical issues, and the emergency brake system is designed to activate and help bring the vehicle to a stop in such an emergency, preventing potential accidents.

Additionally, the emergency brake, often referred to as the parking brake, is crucial for securing the vehicle when it is parked, particularly on hills. Engaging the emergency brake helps to ensure that the vehicle does not roll away, which can be particularly important in preventing accidents or damage to property.

So, the emergency brake system fulfills these vital safety roles by both providing a backup braking method in case of failure and enabling secure parking on slopes, making the correct answer a combination of both stopping in an emergency situation and assisting with parking on hills.
