The brake disc of the disc brake is a round plate that turns as the car moves. Brake calipers are used to create braking force by holding the brake disc between two pieces. Its relatively rotating brake disc is fixed. When you step on the brake, it clamps on the brake disc to slow down or stop. What are the reasons for the better braking effect of brake disc than drum brake?

Disc brake braking force is weak, the actual no drum brake area is large, natural braking efficiency not good drum brake, is only a matter of drum brake is the biggest, hot recession, vigorously limit will make the brake drum brakes fever, eventually led to the gap bigger, longer, is a failure in the end. But the drum brake cost is low, the system power is big, so the truck is used drum brake...

Many small car rear wheel is also drum brake, the cost is low, and small car power, generally used for limit control, so rear wheel drum brake is very economical. But because the front wheel takes 75 percent of the force when braking, it's the front wheel and the back wheel. This includes a lot of rear cars, front and rear brakes, and the front brakes are larger and the back brakes are smaller. In the front is the hollow disc, in the back is the solid disc and so on.

But disc brakes have a gradual process, it is easy to control the brake, and the brake disc rotates with the wheel surface exposed to air, there are few signs of recession heat, long braking can keep good braking effect, some of the super sports car, the use of ceramic fiber before and after the brake disc, is in order to avoid the heat recession.
