Which type of system is known as a cable or electrically operated brake system?

The identification of a cable or electrically operated brake system as a parking brake is based on how these systems are typically designed and employed in vehicles. Parking brakes, also known as handbrakes or emergency brakes, are primarily intended to keep a vehicle stationary when parked.

These systems often utilize cables to engage the braking mechanism, allowing the driver to control the brake manually without relying on the vehicle's regular hydraulic brake system. In many configurations, the parking brake lever pulls on a cable attached to the brake components, creating friction that holds the wheels in place.

Additionally, some advanced vehicle systems have started to incorporate electric parking brakes, which allow for even more convenience and automation. These systems may engage the brake electronically, further emphasizing the association between parking brakes and cable or electrical operation.

In contrast, service brakes, drum brakes, and disk brakes are typically part of the primary braking system that is engaged during regular vehicle operation and are not specifically designed for parking purposes. Therefore, recognizing parking brakes as the system most closely aligned with cable or electronic operation is accurate and aligns with their functional use in vehicles.
