To slow down the vehicle while driving

To secure the vehicle while parked

The primary purpose of using the parking brake is to secure the vehicle while parked. When a vehicle is stationary, especially on an incline, the parking brake helps to ensure that it remains in place and does not roll away. This is crucial for safety, as it prevents accidents that could occur if a parked vehicle were to move unexpectedly. The parking brake engages only the rear wheels and operates independently of the main braking system, which is particularly useful in maintaining stability when the vehicle is not in motion.
