What are the two common types of brakes?

The two common types of brakes are unidirectional self-energizing brakes and bidirectional self-energizing brakes. Introduction to brakes: Brakes are devices that have the function of decelerating, stopping, or maintaining the stopped state of moving parts (or moving machinery). They are mechanical components used to stop or decelerate moving parts in machinery, commonly known as brakes or stops. Composition of brakes: Brakes mainly consist of a brake frame, braking components, and an operating device. Some brakes are also equipped with automatic adjustment devices for the clearance of braking components. To reduce braking torque and structural size, brakes are usually installed on the high-speed shaft of the equipment. However, for large equipment with higher safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft near the working part of the equipment.
As a mechanic who frequently works on cars, I must mention the two most common types of brakes: disc and drum. Disc brakes use calipers to clamp the rotor to stop the vehicle, offering quick response and better heat dissipation, making them less prone to overheating during hard braking—ideal for front wheels or sporty models. Drum brakes rely on brake shoes expanding to create friction against the drum, featuring a simple structure and lower cost, but they dissipate heat slowly and are prone to overheating, though they are still commonly used on rear wheels. For maintenance, disc brakes make replacing brake pads easier, but you need to watch out for rotor wear. Drum brakes require disassembly to clean out dust, as accumulated dust can impair braking performance. It's recommended to check brake pad thickness every 10,000 km. If the brakes feel soft or make unusual noises, don't delay—repairs are affordable and crucial for safety.
