Do You Need to Press the Brake When Turning Off the Engine?

No, you don't need to. After the vehicle comes to a complete stop, shift to neutral or Park (P), engage the parking brake, and then you can turn off the engine. Below is a detailed introduction about automotive brakes: 1. Brakes: Brakes, also known as stopping mechanisms, refer to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The braking device is a mechanical braking mechanism that slows down the vehicle's speed, also known as a decelerator. 2. Braking System: The braking system consists of a control system, hydraulic system, and power assist system. The control system includes the pedal, handbrake, etc. The hydraulic system is composed of hydraulic fluid, brake pump, and hydraulic lines. The power assist system is the vacuum booster. The electronic control system consists of an ABS pump, ABS sensors, and ABS computer. The execution system includes brake calipers, brake pads, and brake discs.
I've been driving for over twenty years and often get asked whether you need to step on the brake when turning off the engine. In automatic transmission vehicles, you must press the brake to shut down the engine because the car has an anti-start system; if you don't, the vehicle might slightly move or sound an alarm the moment the engine stops. I once witnessed a friend forgetting to press the brake before turning off the engine, and the car rolled down a small slope nearly hitting a wall—how scary. Manual transmission cars are more lenient; putting them in neutral or pulling the handbrake can also prevent slipping, but for safety's sake, I recommend everyone develop the habit of pressing the brake when shutting off the engine. Modern cars have complex electronic systems, and pressing the brake helps stabilize voltage to protect electrical components. In short, this simple action can prevent accidents and damage, especially for beginners or when parking on slopes—don't be lazy.
I place a high priority on driving safety and consider turning off the engine while pressing the brake pedal as a fundamental principle. Automatic transmission vehicles are designed to require the brake pedal to be depressed when shutting off the engine; otherwise, the vehicle remains in drive mode, which may cause slight tire rotation and lead to collisions. Imagine parking in a mall garage or on a slope—failing to press the brake before turning off the engine poses significant risks. Having studied automotive engineering, I understand this involves the transmission lock mechanism. While manual transmission vehicles are less strict, pressing the brake can prevent slippage caused by improperly engaged gears. Make it a habit: always press the brake to confirm the vehicle is stationary before shutting off the engine. This not only protects you but also prevents harm to pedestrians or accidental contact with other vehicles.
As an ordinary driver who commutes daily, this is a very practical issue. In an automatic transmission car, I always press the brake to turn off the engine; if I don't, sometimes the car will warn me or not shut down to prevent the wheels from moving. I don't use manual transmission cars much, but I press the brake to prevent rolling. Simply put, pressing the brake once is not troublesome but ensures safety. Remember the procedure: park properly, press the brake, and turn off the engine. Good habits can avoid the embarrassment of needing a tow truck in the middle of the night.
