What Are the Consequences of Driving with the Electronic Parking Brake Engaged?
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 brake is not tightly engaged and the driving distance is short, the impact on the car is minimal, but it causes more wear on the parking brake pads and increases fuel consumption. 2. Tight Engagement: If the brake is tightly engaged and the driver fails to notice it, or if the driving speed is high and the distance is long, the parking brake pads can wear out severely—potentially to the point of needing replacement after just one instance. Excessive wear and heat generation from the brake pads can lead to smoke 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. Assessing the Outcome: If there is no smoke or strong burning smell, there is likely no issue, and no inspection is needed. However, if there is a strong burning smell and visible smoke, check whether the parking brake still functions properly—whether it releases fully when disengaged, whether the braking force remains consistent when engaged, and whether it can still hold the car on a slope.
I often drive to and from work. Once in a hurry, I forgot to release the electronic parking brake before starting, and the car was obviously dragging along with increased engine roar and a sharp spike in fuel consumption. After driving a few hundred meters, I felt something was wrong. Upon checking, I found the brake discs were frighteningly hot. As a result, the brake pads were severely worn, costing me several hundred dollars to repair at the shop, and nearly damaging the electronic control unit. Doing this long-term not only shortens the brake lifespan but could also lead to overheating and fire risks. I recommend developing a habit of checking if the dashboard indicator lights are off or listening for warning sounds before each start. Don't let small mistakes lead to big troubles. Driving requires attention to detail—safety first ensures peace of mind and saves money.
