Is it harmful to drive with the handbrake on for a while?

Driving with the handbrake engaged will most directly cause accelerated wear on the brake discs, hardening of the brake pads due to overheating, and elongation of the handbrake cables. This leads to reduced braking performance, and in severe cases, smoke may emerge from the rear of the vehicle. If driving with the handbrake on for an extended period, it may also result in the brake calipers seizing, brake fluid leakage, and excessively high brake fluid temperature, leading to a complete loss of braking function. Below is some relevant information about the handbrake: 1. Function: It is used to stabilize the vehicle after stopping, preventing accidents caused by rolling on inclined surfaces. 2. Principle: The parking brake only acts on the rear wheels, using two metal cables to pull the rear brake pads to achieve braking.
Once, I drove a short distance of about two kilometers with the handbrake still engaged. After getting out of the car, I noticed the brake discs were extremely hot and even smelled a bit burnt. This is actually quite common, especially among beginners, mainly due to rushing or failing to check the dashboard. The extra friction on the braking system causes heat buildup, and prolonged driving like this can even burn out the brake pads, potentially leading to complete brake failure in severe cases. While driving, you might feel the car dragging, sluggish acceleration, and a noticeable increase in fuel consumption—when I took it to the repair shop, my fuel consumption had risen by at least 10%. To avoid further issues, I immediately found a safe spot to pull over and inspected the brakes. Developing good habits is key: always release the handbrake before starting the engine and avoid rushing to hit the gas. Remember, even if short trips seem harmless, repeated occurrences can significantly shorten brake life, and repairs can easily cost hundreds or even thousands. I recommend glancing at the indicator lights before every start—protect your car and ensure safety.
Driving with the handbrake on can indeed cause problems. Based on my years of driving experience, the severity depends on the distance and road conditions. For example, driving about one kilometer may only cause slight brake pad wear or increased fuel consumption. However, driving more than five kilometers on the highway can have much more serious consequences: overheating of the brakes may lead to disc deformation or even fire. A friend of mine once ruined his car this way, costing thousands in repairs. Additionally, the vehicle will experience increased load, making it harder to drive and the steering wheel heavier. If the warning light on the dashboard comes on, be alert. After parking, immediately check the tires and brake components. If you smell smoke or hear unusual noises, don’t hesitate—take it to a professional shop for inspection. Daily prevention involves training yourself to habitually confirm the handbrake is fully released before starting. Beginners often forget this, so it’s advisable to put a reminder in the car. In short, prioritize safety over luck, and practicing good habits will save you trouble in the long run.
