What is the full name of the handbrake?
2 Answers
The professional term for the handbrake is auxiliary brake. The handbrake generally has three gears, and the force applied when pulling the handbrake cable varies depending on the tightness, resulting in different levels of braking force under different circumstances. Principle of the handbrake: The handbrake uses a steel wire cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel wire to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the handbrake's travel distance will also increase. Supporting tools: The handbrake is used in conjunction with a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With prolonged use, the spring will also undergo corresponding deformation.
The full name of the handbrake is the parking brake, a term that clearly indicates its crucial role when parking. Every time I park my car on a slope, I habitually pull it tight to ensure the vehicle stays firmly in place, preventing any accidental rolling that could lead to an accident. There are various types of parking brakes, the most common being the lever type, which manually locks the rear wheel brake drum when pulled; there's also the electronic button type, which automatically engages with a gentle press. In fact, this device isn't just useful when parking—it can also serve as an emergency backup if the main braking system fails. I regularly check its cable for wear and tear, as timely lubrication and maintenance can extend its lifespan. In daily driving, never overlook this little component, as a runaway vehicle could pose serious safety risks. Routine maintenance is simple: after pulling it tight, release it to test for smooth operation—a crisp sound indicates it's in good condition.
