What are the effects of driving with the electronic parking brake engaged on a car?
2 Answers
Here is a detailed introduction to the consequences of driving with the electronic parking brake engaged: 1. Degree of engagement and driving distance: If the parking brake is not tightly engaged and the driving distance is short, the impact on the car is minimal, but it will cause more wear on the parking brake pads and increase fuel consumption. 2. Tight engagement: If the parking brake is tightly engaged and the driver fails to notice it, or if the car is driven at high speed over a long distance, the parking brake pads will wear out severely, potentially reaching the point of needing replacement after just one instance. Excessive wear and heat generation from the brake pads can lead to smoking and a burning smell. The heat can also transfer to surrounding components, and high temperatures may reduce the strength of these parts or even cause deformation. 3. Outcome assessment: If there is no smoke or strong burning smell, there is certainly no problem, and no inspection is needed. However, if there is a strong burning smell and visible smoke, check whether the parking brake is still functional, whether it can return to its original position after being released, whether the braking force is the same as before when engaged, and whether it can still hold the car on a slope.
When I accidentally forget to release the electronic parking brake while starting the car, it's crucial to be aware. The brake discs and pads endure extra friction, causing temperatures to soar, which may lead to deformation or accelerated wear. Doing this long-term can significantly shorten the lifespan of the entire braking system, leading to costly repairs and potential damage to the drivetrain. Fuel consumption also increases as the engine has to work harder to overcome the brake drag. Worse still, the control system might overheat and fail, posing safety hazards. I always remind myself to develop the habit of checking the electronic parking brake indicator on the dashboard before moving off, ensuring it's off before driving. This protects the car and avoids unexpected risks, especially during frequent starts in urban areas where attention to such details is vital.
