What are the main functional classifications of automotive braking systems?
2 Answers
Automotive braking systems can be classified into the following two types based on their primary functions: 1. Service Brake System: Operated by the driver using the foot, hence also known as the foot brake system. Function: To decelerate a moving vehicle or bring it to a stop within the shortest possible distance. 2. Parking Brake System: Operated by the driver using the hand, hence also known as the hand brake system. Function: To keep a stationary vehicle immobile on various road surfaces. Below is a related introduction to automotive braking systems: I. An automotive braking system refers to a series of specialized devices that apply a certain force to specific parts of the vehicle (primarily the wheels) to enforce a certain degree of braking. II. Functions of the braking system: 1. To forcibly decelerate or even stop a moving vehicle as required by the driver. 2. To ensure stable parking of a stationary vehicle under various road conditions (including on slopes). 3. To maintain a stable speed for a vehicle moving downhill.
When I was learning to drive, I paid special attention to the braking system, which is the foundation of driving safety. It is mainly divided into three functional parts. The service brake is the most commonly used—stepping on the brake pedal to slow down or stop while driving, often referred to as the foot brake. It works through the friction between brake pads and discs, and modern cars are equipped with ABS anti-lock systems to prevent skidding. The parking brake is used when the vehicle is parked, typically a handbrake or electronic button, to prevent the car from rolling on slopes. Experienced drivers know it must be engaged on inclines. The auxiliary brake is designed for specific scenarios, such as downhill driving or heavy trucks, utilizing engine braking or retarders to assist in deceleration and reduce the burden on the service brake. After long-distance driving, I realized how crucial it is—otherwise, the brakes can overheat and fail. In short, no part should be overlooked, and regular checks of brake fluid and wear are essential, as the consequences of failure can be severe.
