Brakes are devices that slow down or stop a motorcycle. There are two commonly used types, one is a disc brake and the other is a drum brake.
Their principle is the same, they use friction to generate braking force, this kind of brake is called friction brake.
The advantage of the disc brake is that the brake is timely, not easy to aging, the brake is not easy to violently die, but the disadvantage is that it is not easy to brake for a long time, and it is easy to brake.
The characteristic of the drum brake is that it will not cause brake failure when braking for a long time, but the time is long, and it is easy for the tire to die.
