Automobile brake pads refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and the friction lining bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Brake pads are also called brake pads. In the brake system of a car, the brake pad is the most critical safety part. The brake pad plays a decisive role in the quality of all braking effects. Therefore, a good brake pad is the protector of people and cars.

So...Automobile brake padsDo you know the brake principle?Automobile brake padsThe working principle is mainly from friction. The friction between the brake pads and the brake discs (drums) and the tires and the ground is used to convert the kinetic energy of the vehicle into frictional heat energy to stop the car. A good and efficient brake 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-cylinder, and avoid hydraulic failure and brake degradation 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. After the force of the driver stepping on the brake pedal is amplified by the lever of the pedal mechanism, the force is amplified by the vacuum power assist using the principle of vacuum pressure difference to push the brake master cylinder.

The hydraulic pressure emitted by the brake master cylinder uses the incompressible power transmission effect of the liquid to be transmitted to each sub-cylinder through the brake hose, and uses the Pascal principle to amplify the pressure and push the piston of the sub-cylinder to exert force on the brake pads. Pascal's principle means that the pressure of a liquid is the same at any position in a closed container.
