Car Brake Pad Basics(一)
1.Automotive brake pads are an important brake system component used to catch the wheels and slow down the speed.
Explanation:Automotive brake pads are one of the core components of an automotive braking system, which converts the kinetic energy of the vehicle into heat energy, thereby slowing or stopping the vehicle's movement.
2. Brake pads are divided into organometallic brake pads and semi-metallic brake pads.
Explanation:Organometallic brake pads are composed of organic materials and metal powder, they not only have good braking effect and low storage power, and relatively cheap. Semi-metallic brake pads, on the other hand, are made up of semi-metallic materials and are more reliable and efficient than organometallic brake pads.
3. Brake pads consist of friction material, support plates and bolts.
Explanation:The friction material is the material used for brake friction, the support plate is the carrier to fix the friction material on the brake system, and the bolts are used to fix the brake pads and brake calipers.
4. The material of the brake pads is inseparable from the friction performance.
Explanation: Different brake pad materials have different coefficients of friction and braking performance, the choice of different materials can be matched to the vehicle's use and driving habits.
5. Brake pad friction material contains copper, iron, graphite, silicon carbide and other components.
Explanation:Different brake friction materials contain different components, these components can improve the friction performance and wear resistance.
6. The grades of brake pads are classified according to braking performance.
Explanation: Brake pad grade refers to the braking performance level of the brake pads, which is usually divided into three levels: Grade A, Grade B and Grade C, corresponding to different braking performance.
7. When brake pads are worn excessively, metal-to-metal friction occurs, causing brake noise.
Explanation:When the brake pads are excessively worn, the metal between the support plate and the hub will collide directly, resulting in a harsh brake noise.
8. The detailed parts of the brake pads need to be cleaned and maintained in a timely manner.
Explanation:The detail part of the brake pad is easy to accumulate debris and dust, if not timely cleaning and maintenance, these debris will affect the overall braking effect and life.
9. Prolonged, high-speed driving tends to overheat the brake pads, and proper deceleration is recommended to reduce the burden.
Explanation:Prolonged, high-speed driving can cause brake pads to overheat, use brake pads to decelerate, and also recommend the use of engine braking, switching gears to slow down properly to relieve excessive heat.
10. The service life of brake pads depends on a number of factors such as the driving environment, vehicle speed and braking method.
Explanation:The wear and tear of brake pads may vary under different driving conditions, while different speeds and braking methods may also have an impact on the service life of brake pads.
