What is the role of emergency brakes in vehicle operation?

The role of emergency brakes in vehicle operation is to provide an extra layer of safety to stop the vehicle in case of failure of the primary brakes. This is crucial for ensuring the vehicle can still be halted effectively even if the main braking system is compromised. Emergency brakes, also known as parking brakes or hand brakes, are designed to engage the braking system independently of the primary brakes, allowing the driver to maintain control and prevent accidents in critical situations. They serve as a backup system that is vital for safety, particularly in emergencies where immediate stopping power is necessary.
