Drum brakes and disc brakes have distinct development trends. Here is an overview:
Drum Brakes
- Limited application in specific fields: Drum brakes are still used in some low - speed and low - cost vehicles due to their simple structure and low manufacturing cost. For example, they are commonly seen on economic - type bicycles, children's bicycles, and certain entry - level automotive models.
- Technological improvement: In the case of electric vehicles, new - generation drum brakes like the Continental EPB - Si are emerging. They combine hydraulic and electronic controls, featuring functions such as automatic gap adjustment for brake pads, corrosion prevention, and low noise. These brakes also have a long service life and a high - torque output, matching well with the characteristics of electric vehicle motors.
Disc Brakes
- Widespread application in various fields: Disc brakes are widely used in high - performance vehicles, heavy - duty vehicles, and most modern cars because of their excellent heat dissipation, reliable performance in different conditions, and easy maintenance. In the field of cycling, disc brakes are also increasingly favored by enthusiasts for their powerful braking force and stable performance.
- Continuous technological innovation: With the development of automotive intelligence and electrification, disc brakes are also being continuously upgraded. For example, the integration with electronic control systems such as ABS and electronic brake - force distribution is becoming more sophisticated, improving vehicle safety and control. Additionally, new materials and manufacturing processes are being applied to disc brakes to enhance their durability and braking efficiency while reducing weight.
