What are the two main types of wheel brakes?

Wheel brakes are divided into drum brakes and disc brakes. The comparison between disc brakes and drum brakes is as follows: 1. Drum brakes are cheaper than disc brakes, and disc brakes are not very suitable for some special environments, such as areas with a lot of sand and gravel, where the brake discs can be easily damaged; 2. 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; 3. Drum brakes have much poorer heat dissipation, and their braking force stability is insufficient, leading to significant variations in braking performance on different road surfaces, making them harder to control. Continuous braking may cause brake fade and failure; 4. The friction area between the brake pads and brake discs 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.
Wheel brakes are generally divided into two types: drum brakes and disc brakes. I've been driving for over twenty years and have seen many brake system issues. Drum brakes have a simple structure, using internal drums and brake shoes for friction braking. They are inexpensive and not complicated to repair, but they have poorer heat dissipation and are prone to failure in rainy weather. I have to regularly check the brake shoe clearance; otherwise, it affects braking performance. Disc brakes are more modern, using rotors and calipers for clamping, offering faster braking response and greater stability during high-speed driving, especially providing a stronger sense of safety on mountain roads or in emergencies. My family car has been upgraded to disc brakes on both front and rear wheels, and maintenance is simpler too. Overall, the choice depends on budget and driving habits—older models often use drum brakes, while newer cars prioritize disc brakes for greater reliability.
There are two main types of wheel brakes: drum brakes and disc brakes. Having worked a lot at the car shop, I can say that drum brakes use a drum-shaped device working with internal brake shoes, making them suitable for economy models. During maintenance, the drum needs to be disassembled to clean dust and rust, which is time-consuming but cost-effective. Disc brakes have a superior structure, with an external rotor design that offers better heat dissipation, reducing the risk of heat fade. Brake pad replacement is quicker, making them ideal for frequent use or complex road conditions. Common issues include reduced braking performance in drum brakes when water gets inside, while disc brakes have ventilation holes to prevent water accumulation. From a safety perspective, disc brakes perform better on wet or slippery roads. It is recommended that aftermarket car owners opt for disc brakes to enhance reliability.
Wheel brakes are divided into two types: drum and disc. I've been into car modifications for several years. Drum brakes slow down through friction inside the drum, which is cost-effective but heavier and slower in response, commonly used in low-end cars. Disc brakes use a rotor and caliper, featuring lightweight design and faster heat dissipation, providing more responsive braking, suitable for high-speed or sports models. I've tried different brands, and disc brakes outperform in terms of heat resistance and braking distance, especially when upgraded with ventilated discs for better performance. For daily driving, disc brakes offer a safer and more comfortable experience. The core difference lies in performance and efficiency.
