Should the Handbrake Be Pulled Up or Down When Driving?

When starting the car, the handbrake needs to be released, and when parking, the handbrake should be pulled up. The commonly referred to "releasing the handbrake" means lowering the handbrake. For small cars, the handbrake is sometimes located behind the transmission, connected to the driveshaft with a brake disc, similar to a disc brake. Then, through a steel cable, the pulling force is transmitted to achieve parking braking. Below is an introduction to the handbrake: The professional term for the handbrake is auxiliary brake. Its principle differs from that of the main brake, as it uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel will increase. Handbrake principle: After pulling the handbrake, it utilizes a hydraulic auxiliary cylinder to push the main hydraulic cylinder beneath the car, which then drives the air valve. Once the air valve is activated, it brakes the driveshaft. The handbrake only brakes the driveshaft. After completing the braking of the driveshaft, in the case of ordinary trucks, the handbrake lever's steel cable is pulled to achieve long-term braking.

When driving, the handbrake must be completely released and never engaged. Once, I forgot to release the handbrake and drove a short distance, which caused the brake pads to wear out unusually fast and even produced a burning smell. That experience made me realize it was a serious mistake. Driving with the handbrake engaged keeps the rear brakes dragging, leading to overheating, deformation, and even shortening the lifespan of the brake pads. In severe cases, it could cause a fire or loss of control. Now, before every trip, I habitually check to ensure the handbrake is fully released. Especially when starting on a slope, always release the handbrake before starting the engine to ensure safety. Developing this habit not only protects the car's braking system but also reduces the risk of accidents.

When I first started learning to drive, my instructor repeatedly emphasized the importance of releasing the handbrake before driving. He said that starting the car with the handbrake engaged is a common mistake made by beginners, which can put excessive load on the rear wheels, potentially over-tighten the brake cables, and affect the overall drivetrain. Now I understand that the handbrake is designed for parking stability, and using it while driving adds unnecessary resistance, forcing the engine to work harder. This not only wastes fuel but also impacts performance. It's advisable to develop a good habit of checking, especially glancing at the dashboard before starting the engine to ensure the handbrake indicator is off. This may seem like a small thing, but it can save you from costly repairs and make driving smoother.

As a car enthusiast, I know the proper use of the handbrake: engage it when parking to prevent rolling, and always release it when driving. Keeping the handbrake engaged continuously applies pressure to the brake shoes, causing excessive friction and heat, which over time can warp or crack the brake discs. I once saw a car at a repair shop that cost over a thousand dollars in parts replacement due to this issue. Simply put, releasing the handbrake frees the system, allowing the car to run smoothly. If you check before starting and notice the warning light is on, address it promptly.
