Brakes currently include disc brakes and drum brakes. Many older cars have front disc and rear drum brakes. Many modern cars now have disc brakes on both front and rear. Because disc brakes dissipate heat better than drum brakes, they are less prone to thermal degradation during high-speed braking, thus providing better braking performance at high speeds.
The principle of disc brakes is: braking primarily comes from friction, utilizing the friction between the brake pad and the brake disc (drum) and between the tire and the ground, converting the kinetic energy of the moving vehicle into heat generated by friction to stop the car. A good braking system can provide stable, sufficient, and controllable braking force, along with good hydraulic transmission and heat dissipation capabilities, to ensure that the force applied by the driver on the brake pedal is fully and effectively transmitted to the master cylinder and each sub-cylinder, and to prevent hydraulic failure and brake fade caused by high heat.
The material determines the braking level and wear speed. For example, most new Octavia owners report brake noise because of the material of the rear brake pads; the problem is resolved after replacing them with imported brake pads. When the brake pads are excessively worn and become thin, they should be replaced promptly to prevent direct contact between the steel plate and the brake disc, which would lead to loss of braking effect and damage to the brake disc. The part that is acted upon by the brake pads and rotates with the wheel is called the brake disc.
Car owners can usually judge the quality of brake discs by the sound of daily braking, especially after the vehicle has been used for a long time. For example, if there is a hissing sound or a loud noise when the brake pads rub against the brake disc during light braking, you can try it a couple more times to prevent sounds generated during the initial break-in period after brake pad installation. Brake discs have low thermal degradation, good recovery performance, and maintain braking performance on mountain roads and under high temperature and high-speed conditions. This significantly enhances vehicle safety. It is very suitable for use on mountain roads, highways, and various other road conditions!
