With the continuous development of automotive technology, the design and performance of braking system, as a key component to ensure driving safety, has also attracted increasing attention. Drum brakes and disc brakes are two common braking systems, each with its own characteristics.

Drum brakes work by using the friction between the brake drum and the brake shoe to generate braking force. When the brake pedal is pressed, the brake fluid enters the inside of the brake drum and pushes the brake shoe into contact with the brake drum, creating a braking force. The working principle of disc brake is to transmit the pressure of brake fluid to the brake pad through the hydraulic system, so that the brake pad is in close contact with the brake disc, so as to achieve braking.

In terms of braking performance, drum brakes usually have a high braking torque, which can provide effective braking for the vehicle in a short time. Disc brakes, on the other hand, have a faster braking response and are capable of braking multiple times in a short period of time. In addition, disc brakes are also better than drum brakes for heat dissipation, allowing them to maintain stable braking performance after long periods of high-speed driving.

The structure of the drum brake is relatively simple, and the maintenance cost is low. Since the brake drum and shoe are in direct contact, wear parts need to be replaced regularly. The structure of disc brakes is more complex and the maintenance cost is relatively high. Since there is a gap between the brake pads and the brake disc, the clearance needs to be adjusted regularly to ensure braking performance.

The advantages and disadvantages of drum brakes and disc brakes

1. Braking performance

In terms of braking performance, drum brakes usually have a high braking torque, which can provide effective braking for the vehicle in a short time. Disc brakes, on the other hand, have a faster braking response and are capable of braking multiple times in a short period of time. In addition, disc brakes are also better than drum brakes for heat dissipation, allowing them to maintain stable braking performance after long periods of high-speed driving.

2. Structure & Maintenance

The structure of the drum brake is relatively simple, and the maintenance cost is low. Since the brake drum and shoe are in direct contact, wear parts need to be replaced regularly. The structure of disc brakes is more complex and the maintenance cost is relatively high. Since there is a gap between the brake pads and the brake disc, the clearance needs to be adjusted regularly to ensure braking performance.

Although drum and disc brakes have their own advantages and disadvantages, why don't anyone wait to see drum brakes? There are several reasons for this:

In the eyes of many people, the image of the drum brake is relatively old and not modern enough. In contrast, disc brakes are more stylish and advanced. As a result, some people prefer to choose a model with disc brakes when choosing a car.

Due to the quality problems of the drum brakes of some early cars, some people questioned the reliability of the drum brakes. In contrast, disc brakes, as a more modern braking system, are considered more reliable and safe. As a result, some people prefer to choose a model with disc brakes when choosing a car.

For some motorists, they are more accustomed to using the traditional accelerator pedal to control the speed of the vehicle rather than using the brake pedal. In this case, they may feel that the drum brakes are not sensitive and linear enough, leading them to prefer to use disc brakes.

In summary, drum and disc brakes have their own advantages and disadvantages, and which braking system to choose depends on the individual's needs and preferences. However, no matter which braking system you choose, you should pay attention to regular maintenance and upkeep to ensure driving safety.
