What are the two common types of brakes?

[Jake]

Brakes are divided into drum brakes and disc brakes. The comparison between disc brakes and drum brakes is as follows: In terms of cost: Drum brakes are cheaper than disc brakes, and disc brakes are less suitable for some special environments, such as areas with a lot of sand and gravel, where the brake discs are more prone to damage. In terms of heat dissipation performance: Disc brakes have excellent heat dissipation performance, and the braking system responds quickly, allowing for high-frequency braking actions. Compared to drum brakes, disc brakes have a simpler structure and are easier to maintain. Drum brakes have much poorer heat dissipation, and their braking force stability is insufficient, with significant variations in braking performance on different road surfaces, making them harder to control. Continuous braking may lead to brake fade and failure. In terms of brake pads: The friction area between the brake pads and the brake disc in disc brakes is smaller than that in drum brakes, resulting in less braking force. Additionally, the brake pads wear out more quickly and require more frequent replacement.
