Braking system is an important part of automobile safety, it can effectively decelerate or stop to avoid traffic accidents. In the automobile market, there are two common braking systems: drum brake and disc brake. So, what's the difference between them? This article will make a detailed comparison and analysis from many angles to help car owners.20betcasino50freespinsUnderstand the characteristics, advantages and disadvantages of these two brake systems.
one20betcasino50freespins. Structure and working principle
The working principle of drum brake is to decelerate or stop through the friction between brake shoe and brake drum. The brake shoe is in the brake drum, which rotates with the rotation of the wheel. When the driver presses the brake pedal, the brake shoe is pressed on the brake drum, causing friction to slow down or stop.
Unlike the drum brake, the brake disc of the disc brake is a rotating disc with brake calipers fixed on both sides of the brake disc. When the driver presses the brake pedal, the brake caliper will exert pressure on the brake disc, causing friction between the brake shoe and the brake disc, so as to slow down or stop.

Because the brake shoe and drum of the drum brake are wrapped in a closed space, the heat dissipation performance is relatively poor. When driving for a long time or at high speed, the brake drum may lead to a decline in braking effect due to overheating, thus affecting driving safety.
In contrast, the disc brake disc is exposed to the air and has better heat dissipation performance. Even in the case of long-term or high-speed driving, the brake disc can dissipate heat quickly through air flow to maintain a stable braking effect.
3. Braking effect
Disc brakes are usually better than drum brakes. Because the contact area between the brake shoe of the disc brake and the brake disc is larger, the friction force is also greater, thus achieving a faster and more stable braking effect. In addition, the brake calipers of the disc brake can also be adjusted according to needs to adapt to different driving conditions and vehicle loads.
However, the braking effect of drum brake is limited by the contact area between brake shoe and brake drum, which is relatively poor. On emergency braking or slippery roads, drum brakes may not provide sufficient braking effect, thus affecting driving safety.
4. Cost and maintenance
The structure of drum brake is relatively simple and the manufacturing cost is low. However, due to the poor heat dissipation performance of the drum brake, the brake shoe and drum need to be replaced regularly, and the maintenance cost is relatively high.
In contrast, the manufacturing cost of disc brake is higher, but because of its good heat dissipation performance and stable braking effect, the maintenance cost is relatively low. In addition, the brake calipers of the disc brake can be adjusted as needed to provide20betcasino50freespinsHigher flexibility and adaptability.
Summary:
Drum brake and disc brake have their own advantages and disadvantages. When choosing the braking system, car owners need to consider comprehensively according to their own driving habits, vehicle type and budget. Drum brakes are suitable for economical vehicles or short-distance driving, while disc brakes are more suitable for high-performance vehicles or long-distance driving. No matter which brake system is chosen, regular maintenance and inspection is an important measure to ensure driving safety.
