Braking principle
The working principle of the brake is mainly from friction. The friction between the brake pad and the brake disc (drum) and the tire and the ground is used to convert the kinetic energy of the vehicle into the heat energy after friction and stop the car. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder And each sub-pump, and avoid hydraulic failure and brake recession caused by high heat. The brake system on the car is divided into two categories: disc and drum, but in addition to the cost advantage, the efficiency of drum brakes is far less than that of disc brakes.

friction
"Friction" refers to the resistance to motion between the contact surfaces of two opposing moving objects. The size of the friction force (F) is proportional to the product of the friction coefficient (μ) and the positive pressure (N) in the vertical direction on the friction force surface, which is expressed in the physical formula: F=μN. For the brake system: (μ) refers to the friction coefficient between the brake pad and the brake disc, and N is the force (Pedal Force) exerted by the brake caliper piston on the brake pad. The larger the friction coefficient, the greater the friction force, but the friction coefficient between the brake pad and the disc will change due to the high heat generated after friction, that is to say, the friction coefficient (μ) is the change with temperature. However, each brake pad has a different friction coefficient curve due to different materials. Therefore, different brake pads will have different optimal working temperatures and applicable working temperature ranges. This is when you buy brake pads. all you need to know.

transmission of braking force
The force exerted by the brake caliper piston on the brake pads is called the Pedal Force. After the force of the driver stepping on the brake pedal is amplified by the lever of the pedal mechanism, the power is amplified by the principle of the vacuum pressure difference through the vacuum power booster to push the brake master cylinder. The hydraulic pressure from the brake master cylinder utilizes the incompressible power transmission effect of the liquid, which is transmitted to each sub-pump through the brake oil pipe, and the "Pascal's principle" is used to amplify the pressure and push the piston of the sub-pump to exert force on the brake pads. "Pascal's Law" (Pascal's Law) means that the liquid pressure is the same anywhere in a closed container.
The pressure is obtained by dividing the applied force by the force-receiving area. When the pressure is equal, we can achieve the effect of power amplification by changing the size ratio of the force-applying area and the force-receiving area (P1=F1/A1=F2/A2=P2) . Used in the brake system, the ratio of the master cylinder to the cylinder pressure is the ratio of the master cylinder piston area to the cylinder piston area.

brake pads
High-performance brake pads are the most direct, effective and simple way to improve braking power. At present, most of the high-performance brake pads use carbon fiber and metal materials as the main raw materials, and emphasize the environmentally friendly formula without asbestos. Since the Know-How of brake pads lies in the material formula, consumers cannot know the actual material from the product label. Therefore, the choice of brake pads is based on the friction coefficient-temperature curve and applicable working temperature provided by the manufacturer. (if any), only test reports or experience from professional media can be used as a reference. There are car owners who misuse pure competitive brake pads and spend a high price to get a braking effect that is worse than the original brake pads. The reason is that its gentle driving style keeps the brake pads from reaching the most basic working temperature. Of course the effect is bad. The most common problem when changing the brake pads is the accompanying noise. If the disc is flat, there is no solution. Either accept it or change it.
