Does Turning Off the Engine Before Engaging the Handbrake Have Any Impact?

Regular handbrakes are mechanical and can be engaged or released at any time. Below is relevant information about engine stalling: 1. Reasons for stalling: Automatic transmission models: Vehicles with automatic transmission rarely experience stalling, whereas manual transmission models may stall frequently due to lower driving proficiency. However, it's not impossible for automatic transmission vehicles to stall; the primary cause is the use of substandard fuel leading to engine carbon buildup and stalling. 2. Precautions: For automatic transmission vehicles stalling, the main reason is the use of inferior fuel. It is advisable to refuel at reputable, larger gas stations with higher-grade fuel, such as 97-octane gasoline. Although more expensive, it ensures longer vehicle lifespan and better driving performance.

I've been driving for many years and think that turning off the engine before engaging the handbrake is generally fine, but it's not a good habit. Especially on slopes, if you turn off the engine first, the car might roll slightly before stopping, which increases the burden on the handbrake and causes faster wear on the brake pads over time. I always insist on engaging the handbrake before turning off the engine—this keeps the car more stable, particularly on urban slopes or in crowded parking lots, preventing minor accidents like rolling into a wall or another car. Developing the correct sequence is simple: when parking, don’t rush to turn off the engine; first, firmly engage the handbrake, confirm the car doesn’t move, and then shut off the engine. Don’t stress if you mess up occasionally—modern cars are designed to be sturdy and won’t have major issues right away—but for safety, it’s better to be consistent. During routine brake system maintenance checks, mechanics also remind you of this to ensure longer-lasting parts.

As a safety-conscious individual, I believe there are potential risks in turning off the engine before engaging the handbrake. If the car hasn't come to a complete stop before shutting off the engine, especially on mountain roads or inclined surfaces, the vehicle might slightly slide before being held by the handbrake, increasing the chance of accidents. For example, when parking on a slope, I strongly recommend engaging the handbrake first and then turning off the engine. This protects the parking brake system and prevents the car from moving and causing harm to people or objects. In the long run, although incorrect sequence doesn't directly damage the vehicle, it may accelerate the aging of braking components. Developing the right habit while driving is simple: stop, engage the handbrake, and then turn off the engine—a one-step process for safety and peace of mind. Occasional negligence may not be a big issue, but prevention is always better than regret. Ensuring driving safety is of utmost importance.

From a mechanical perspective, turning off the engine and then applying the handbrake has minimal impact, as the parking brake can still function, though the instantaneous load may be slightly higher, potentially increasing friction. Incorrect sequence: applying the handbrake after turning off the engine might allow the car to slide slightly before stopping, leading to slightly faster wear on the brake cables or pads. However, modern cars are designed to be durable, and major malfunctions are rare. It's better to apply the handbrake first before turning off the engine to ensure the system operates normally.
