What are the differences between expanding brakes and drum brakes?

[AustinDella]

Here are the differences between expanding brakes and drum brakes: Difference in sound: Expanding brakes produce loud and harsh braking noises, notorious as an ear killer. Most electric vehicles on the road today use this type of brake, which offers poor braking performance. Originally designed for bicycles, they perform adequately on bicycles but only moderately on electric vehicles. Drum brakes, once the brake pads are properly worn in, operate silently. Difference in performance: Drum brakes offer better braking performance and are commonly used on motorcycles with a displacement of 125cc. They are also cost-effective, providing good value for money. Once engaged, the wheels do not move in any direction, ensuring safety, making them very suitable for electric vehicles. Disc brakes provide excellent braking performance and are used on high-displacement motorcycles and sports cars (including four-wheeled vehicles). Once engaged, like drum brakes, the wheels do not move.
