The primary function of the emergency brake system, also known as the parking brake or handbrake, is to provide a means of stopping the vehicle during a brake failure when the regular hydraulic brakes are compromised. This system is designed to engage the rear brakes independently from the primary braking system, allowing the driver to halt the vehicle safely if the main brake system fails. It serves as a critical safety feature, ensuring that drivers have an additional layer of control over their vehicle in emergency situations.

While the emergency brake can also be used for holding a vehicle stationary when parked, its most crucial purpose is to serve as a backup in situations where the primary braking system does not function correctly. Understanding this vital role helps ensure that drivers recognize the importance of maintaining their emergency brake in good working condition.
