盘刹与鼓刹的优缺点2（Advantages and disadvantages of disc brake and drum brake 2） Drum brake disc brake power relatively poor, poor heat dissipation, but good waterproof ability than disc brakes.

But there are a lot of off-road vehicles or the distribution of front disc and drum brake (such as Hummer), it can guarantee the maximum braking force, general car or car with four wheel disc brakes.
