Is the car brake good disc or drum?
Drum brake, also known as block brake, is pressed by the brake block on the brake wheel to realize the brake. Drum brake is an early designed brake system, and its brake drum design has been used in the carriage since 1920. It was not until around 1902 that it began to be widely used in the automobile industry.
And because of poor heat dissipation, a large amount of heat will be collected during braking. The brake block and drum are prone to complicated deformation under the influence of high temperature. The brake depression and chattering phenomenon are easy to occur, which results in the decrease of braking efficiency.
Compared with disc brake, drum brake has poor braking performance and heat dissipation. The brake stability of drum brake is poor, and the braking force varies greatly on different roads, and it is not easy to control.
Now the drum brake is the mainstream of the internal style, its brake block (brake shoe) is located in the brake wheel inside, when the brake, the brake block open outwards, friction brake wheel on the inside, to achieve the purpose of braking
