Which type of brake system should be used for parking a vehicle securely?

The parking brake system is specifically designed for securing a vehicle when it is parked. It is intended to hold the vehicle stationary, preventing it from rolling away, especially on inclines or uneven surfaces. This system operates independently of the service brake and is activated by a lever or pedal, ensuring reliability when the vehicle is not in motion.

While the service brake system is used to slow down or stop the vehicle while driving, and the emergency brake system is typically used to bring a vehicle to a stop in the event of a failure of the primary braking system, neither is meant exclusively for parking purposes. The primary function of the parking brake is to keep the vehicle in a fixed position, making it the optimal choice when securing a parked vehicle.
