Which statement best describes the emergency brake usage?

• A. A device to start the engine.
• B. The parking brake; use to secure the vehicle when parked or in an emergency if the regular brakes fail.
• C. A backup braking system that should be used routinely at high speeds.
• D. A tool to help steer in a pinch.

Answer: (B)

The emergency brake, often called the parking brake, is a separate brake system used to keep the vehicle from rolling when parked and to provide a backup in a brake failure scenario. It’s designed to hold the car in place when you’re stopped and to be used if the regular braking system fails, but it’s not meant for normal stops or for high-speed braking. It can lock the rear wheels and reduce steering control if used improperly, so it’s not a substitute for regular brakes or for steering assistance.

That’s why this description fits best: it describes a device intended to secure the vehicle when parked and to serve as a backup in an emergency if the regular brakes fail.
