First of all, let's talk about the most controversial drum brake. The drum brake is in a closed space as a whole. The static brake pads in the brake drum are used to rub the brake drum that rotates with the wheels through the injection of brake oil to slow down the car. Because of its large friction area, the braking force is also large. In some large trucks and buses, the frequency of use will be higher. However, the heat dissipation performance of the drum brake will be poor. After all, it is in a closed space. At the same time, the rust stains in the brake drum can not be discharged anywhere, so it can only be accumulated and cleaned regularly. Especially in high-speed driving, the heat dissipation of the brake is poor, and it is easy to accumulate heat to cause heat exhaustion of the brake, resulting in weakening of the braking force, so there is a hidden danger of brake failure.
The advantages of the disc brake will be obvious. At present, it has been widely used in household cars and performance cars. It has the characteristics of fast heat dissipation, light weight, fast braking and convenient adjustment. Most of the brake discs are made of steel, while some performance cars and supercars will use all-carbon or ceramic materials. Because its heat dissipation is very fast, it has obvious advantages in the continuous braking process. https://www.yhxbrake.com/brake-pad-for-toyota
The brake pad and the brake disc are in plane contact, and the braking is fast, which is very suitable for frequent braking.
For our family cars, the brake effect of the disc brake is better. Large vehicles like buses need greater brake effect, and the drum brake will be more suitable. As the most basic and important guarantee for perfect driving safety, the brake of the vehicle needs to be checked regularly. After all, life is not a joke. It is for the safety of ourselves and others.
