I believe that anyone who understands cars knows that the braking of a car is completed by multiple components in a complex system. At present, the braking system of a car is mainly divided into two types: disc brakes and drum brakes. The braking system mainly makes the road exert a certain force on the wheels of the car, which causes the car to brake.

What is the difference between drum brake pads and disc brake pads?

Drum brake is a traditional braking system. The working principle of drum brake is simple. It is composed of brake oil pump, piston, brake pad and drum chamber. When braking, the piston is pushed by the high-pressure brake fluid of the brake cylinder. Apply force to the two half-moon-shaped brake shoes to press them against the inner wall of the drum chamber, and rely on friction to prevent the brake drum from rotating to achieve the braking effect.

Disc brakes are also called disc brakes, which are mainly composed of brake discs, brake calipers, friction plates, sub-cylinders, oil pipes and other parts. Disc brakes, also called "disc brakes", as the name suggests, are mainly composed of brake discs (brake discs) and brake calipers. When the wheel is working, the brake disc rotates with the wheel. When the brake is working, the brake caliper pushes the brake pad to rub against the brake disc to produce braking.

In fact, the braking performance is also closely related to the price of the car. The braking technology and materials used in high-priced high-performance sports cars will naturally be better, and the braking distance is shorter than that of family cars. In fact, as long as you understand the basic principles of braking, it is better to buy a car according to your own needs. No matter what kind of braking method, it can definitely ensure driving safety.
