What is the function of a car handbrake?

[MasonMarie]

The function of the handbrake is to prevent the car from automatically sliding when unattended, avoiding traffic accidents. The following is a related introduction about the handbrake: 1. Introduction: The professional term for the handbrake is auxiliary brake. Unlike the principle of the brake, it uses a steel wire cable connected to the rear brake shoe to brake the car. Long-term use of the handbrake will cause plastic deformation of the steel wire. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the travel of the handbrake will also increase. 2. Composition: It consists of a brake lever, cable, brake mechanism, and return spring, acting on the drive shaft or rear wheel brake to achieve vehicle stability.

I've been driving for many years, and the handbrake is like a daily safety assistant. It effectively prevents the car from rolling away when parked, especially on slopes or uneven roads. Without engaging the handbrake, the car might slide on its own, leading to accidents. I remember one time when I parked on a mountain road to enjoy the view and didn't tighten the handbrake properly—the car slowly rolled toward the edge of a cliff. It was terrifying, and since then, I've never been careless about it. Besides securing the car when parked, the handbrake can also help slow down the vehicle in emergencies, such as when the main brakes fail, preventing collisions. Regular maintenance is essential—check the cables for wear or looseness and ensure the dashboard light turns off after releasing the handbrake before driving, as neglecting this can damage the braking system. In short, making it a habit is always better than skipping it.

After working in the auto repair shop for so long, I often see car owners coming to ask about handbrake issues. It's essentially a mechanical parking brake device. When engaged, it activates the rear wheel brake shoes via a cable to secure the vehicle, preventing rolling risks when parked. After installation, the tightness must be tested – too loose and it may be ineffective, too tight and it becomes hard to pull, potentially damaging the car. Common failure points include cable rust/jamming or friction pad wear. Regular cleaning and maintenance are recommended to prevent hazards. In emergencies like brake failure, it can serve as a backup braking system, but don't expect it to completely stop a high-speed vehicle. Always release it before driving, otherwise it'll increase fuel consumption and damage components.

When I first started learning to drive, the instructor kept emphasizing that pulling the handbrake when parking is basic common sense. Its function is to secure the vehicle and prevent it from moving unexpectedly, such as when temporarily stopping at a traffic light or waiting for a friend by the roadside, which helps avoid dangerous unintended sliding. Beginners are most prone to forgetting to release it, driving with the brake engaged, which is bad for the brakes and wastes fuel unnecessarily. Developing good habits can enhance driving safety—simple actions with significant implications.

As an urban commuter who drives to work every day, I always use the handbrake. When parking in crowded lots or on sloped residential streets, it prevents the car from rolling into vehicles in front or behind, saving a lot of trouble and repair costs. In emergencies like being rear-ended at a red light, engaging the handbrake helps stabilize the car and reduce impact. Remember to make it a habit to always pull the handbrake when parked—don't cut corners, safety comes first. For maintenance, keep the cable dry to prevent aging.
