We often see drum brakes on the rear wheels of the rear wheels, and the same models in the four-wheel brakes will appear in the high-distribution vehicles. This has also prompted some consumers to form a potential awareness of drum brakes. In fact, from the mechanics principle, the disc brakes are not necessarily "high", and the drum brakes are not necessarily "inferior"!
Disc brakes are the most widely used brake system on passenger cars. Their main structure consists of brake discs, brake calipers and control systems. The working principle is that the oil pressure is used to push the brake disc in the brake caliper to clamp the brake disc, and the purpose of the deceleration wheel and the vehicle braking is obtained.
First of all, the appearance of the disc brake is more refined and scientific and technical than the drum brake. In addition, the disc brake has good heat dissipation and drainage performance, rapid response and uniform power, which is suitable for high frequency braking. This is also in line with the working requirements of active safety systems for vehicles such as ABS and ESP, so most of the current cars, SUVs and other vehicles use this type of braking.
Due to the phase contrast of the disc brakes, the cost of the brakes is slightly higher, so some models are low-match versions, and the ratio of using front-wheel brakes and drum brakes reduces costs.
