When should the emergency brake be used?

The emergency brake, also known as the parking brake or handbrake, is specifically designed to secure the vehicle when it is parked, particularly on an incline. Its primary use is in situations where the regular brake system might fail, making it essential during true emergencies. This includes situations where the driver needs to quickly secure the vehicle from rolling when the primary brake system is compromised or in a situation where stopping down a steep grade is necessary, thus providing additional security.

Using the emergency brake in other scenarios, such as in all driving conditions or whenever you stop the vehicle, can lead to unintended consequences, like wear and tear or malfunctioning of the brake system. While it helps prevent a vehicle from rolling back on hills, its misuse in regular driving conditions can be counterproductive. Thus, the best practice is to reserve the emergency brake for true emergencies where its application ensures safety.
