What are the two types of wheel brakes?

Wheel brakes are divided into drum brakes and disc brakes. The comparison between drum brakes and disc brakes includes the following two aspects: 1. Advantages; (1) Drum brakes: Drum brakes are cost-effective and conform to traditional design. For heavy-duty vehicles, since the speed is generally not very high, the durability of the brake shoes is also higher than that of disc brakes; (2) Disc brakes: Disc brakes have good heat dissipation performance, and the braking system responds relatively quickly, allowing for high-frequency braking actions. Compared to drum brakes, disc brakes have a simpler structure and are easier to maintain. 2. Disadvantages: (1) Drum brakes: Poor heat dissipation, insufficient braking force stability, significant braking variations on different road surfaces, difficult to control, and continuous braking may cause brake fade and failure; (2) Disc brakes: Disc brakes are more expensive and are not suitable for some special environments, as they can easily damage the brake disc. The friction area between the disc brake pads and the brake disc is smaller than that of drum brakes, resulting in weaker braking force. Additionally, the brake pads wear out more quickly and require more frequent replacement.
There are two main types of wheel brakes: disc brakes and drum brakes. Disc brakes use a metal disc clamped by brake pads for braking, offering fast heat dissipation and excellent braking performance, especially providing higher safety at high speeds or in rainy conditions. Drum brakes, on the other hand, utilize brake pads inside a drum-shaped housing for friction-based braking, featuring a simpler structure and lower cost but poorer heat dissipation, which may lead to performance degradation after rain due to water accumulation. Having driven various vehicles, I've noticed many new cars combine disc brakes on the front wheels with drum brakes on the rear, balancing efficiency and cost. Regular maintenance should include periodic checks on brake pad wear and disc surface cleanliness to avoid overheating from prolonged braking, which can affect lifespan. When choosing, consider personal habits: prioritize disc brakes for frequent mountain driving, while drum brakes are more economical for city commuting. Overall, front-wheel braking is significantly more critical.
As a seasoned driver, I deal with two types of wheel brakes in daily use: disc and drum. Disc brakes use a rotor and caliper for quick stopping, offering responsive performance with a single press. Drum brakes activate inside the drum, requiring deeper pedal engagement with initially weaker force. Disc brakes excel in heat dissipation under high loads, resisting fade, though maintenance costs are slightly higher. Drum brakes are cost-effective and durable but may squeak when wet. During rainy road tests, I found drum brakes more prone to slipping, so I recommend frequent checks on tire pressure and braking distance. Different vehicles use different setups: off-roaders often favor drum brakes for dust resistance, while sedans balance safety with front discs and rear drums. Never neglect regular brake fluid changes, or the system may fail.
