Does applying the electronic handbrake in D gear damage the car?
3 Answers
Applying the electronic handbrake directly in D gear will not damage the vehicle. The electronic handbrake is a technology that uses electronic control to achieve parking braking. Its working principle is similar to that of a mechanical handbrake, both of which control parking braking through the friction generated between the brake disc and brake pads. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. The car's electronic handbrake, also known as the Electronic Parking Brake (EPB), is marked with a "P" button on the vehicle. Its working principle is the same as that of the traditional mechanical handbrake, both achieving parking braking through the friction between the brake disc and brake pads. The only difference is that the control method has changed from the previous mechanical handbrake to an electronic button. Method to activate the electronic handbrake: Press the brake pedal and pull the electronic handbrake switch upward until the indicator light on the dashboard lights up. At the same time, the indicator light on the handbrake switch will also light up. If the vehicle is turned off without activating the electronic handbrake, the electronic handbrake will be automatically activated. Method to deactivate the electronic handbrake: Press the electronic handbrake switch while stepping on the brake. At this time, the indicator lights on the dashboard and the switch will turn off. Pressing the accelerator while the engine is running can automatically release the electronic handbrake.
I've been driving automatic transmission cars for over a decade and have tried pulling the electronic parking brake while in D gear a few times. The car would lurch forward slightly, which feels quite unnatural. Modern cars do have safety designs—for instance, my car will emit a warning sound or automatically release the parking brake—but this doesn't entirely prevent wear and tear. The core function of an electronic parking brake is to apply braking force to the rear wheels, while the transmission continuously delivers power in D gear. Frequent or prolonged operation can cause friction wear on the brake pads and drive shafts, potentially shortening component lifespan. In daily use, I always follow this sequence when parking: press the brake pedal first, shift to N or P gear, and then engage the parking brake for a smoother stop. Developing good habits can also reduce repair costs, as replacing parts isn't cheap—especially in urban areas with frequent traffic lights, where paying attention to this small detail becomes even more important.
As an ordinary car enthusiast, I must say that pulling the handbrake while in D gear is really not advisable. If the transmission system gets damaged, you'll have to pay for repairs. The electronic handbrake essentially controls the brakes via an electric motor and is designed for use when stationary. In D gear, the vehicle tends to move, and forcibly pulling the handbrake can cause conflicts leading to premature wear of components. From my experience, I've never operated it this way—I always follow the proper procedure: after coming to a complete stop, shift to P gear and then engage the handbrake, which is safe and reliable. One more thing: many new cars now come with an auto-hold function that can hold the wheels at traffic lights without manual intervention. This design is much more considerate. Don’t overlook these small tips—they can extend your car's lifespan.
