Is Driving with the Handbrake Not Fully Released Harmful to the Car?

Driving with the handbrake not fully released is very harmful to the car, as it accelerates tire wear and damages the handbrake system. Handbrake: Professionally known as an auxiliary brake, it operates differently from the main brake system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Hazards: Driving with the handbrake engaged directly causes accelerated wear on the brake discs and hardening of the brake pads due to overheating, as well as stretching of the handbrake cable. If driving with the handbrake engaged for an extended period, it may also lead to the brake caliper seizing, brake fluid leakage, excessively high brake fluid temperature, and complete loss of braking function.
Last time my buddy forgot to release the handbrake and drove hard for two kilometers. When we took it apart at the repair shop, the brake discs had blue scorch marks. The mechanic said this situation is most damaging to the brake calipers—the high temperature can deform the oil seals, causing brake fluid leaks, and in severe cases, the entire brake caliper may need replacement. Plus, the tires were terrifyingly hot to the touch, and fuel consumption skyrocketed. Now I get nervous whenever I see that red exclamation mark on the dashboard. I recommend everyone take a quick glance at the dashboard before driving—don't rely solely on warning sounds, as loud music can sometimes drown them out. Developing the habit of checking the handbrake before starting can save you thousands in repair costs.
My driving instructor always says that driving with the handbrake on is like running in high heels. Even if it's not fully engaged, the rear brake pads and discs keep grinding against each other. After just 3-5 kilometers, you can smell burning. Last time my old car went through this, the repair shop said the rear wheel bearing grease had melted from the heat, and it cost over 800 yuan to replace the bearing. What's worse, overheated brakes can lead to reduced braking power, which is especially dangerous when going downhill. I recommend checking the dashboard at traffic lights—if the handbrake light is slightly lit, stop immediately to inspect it. Don't wait until you smell something burning to take action.
