How often does the Brake Pad Change?

Brake pads are one of the important components of the braking system, which is very important to ensure the safety of the vehicle. However, the brake pads are actually wearing pants. Many owners may not know how often the brake pads need to be replaced. When problems occur, they are often over-serviced, which will cause certain safety risks to the vehicle. What are brake pads?

Brake pads are also called brake pads. In a car's brake system, the brake pads are the most critical safety part. All the brake effects are decisive. Therefore, a good brake pad is the protector of people and cars. The materials of the brake pads are different. For example, the Hummer Brake Pad, Lincoln Brake Pad, Mini Brake Pad, and other materials are different, which also affects the service life. The working principle of the brake is mainly to use the friction between the brake pads and the brake disc (drum) and the tire to the ground to convert the kinetic energy of the vehicle into frictional heat energy to stop the vehicle. If the brakes fail, the consequences are unimaginable. How often are the brake pads replaced?

Because the material of the brake pads is different, everyone ’s driving habits are different, the driving conditions are different, and the frequency of using the brakes is different, so the wear of the brake pads will be different. In addition, the wear degree of the front and rear brake pads of the same car may also be different (generally, the front brake wears quickly), and the automatic transmission and manual transmission will also be slightly different (the automatic transmission will often loosen the brake when the vehicle is blocked), which cannot be generalized.

Brake Pad

Determine whether the brake pads need to be replaced? First of all, the thickness of the new brake pad is usually about 1.5CM, but after continuous friction, it will gradually become thinner, and professional technicians suggest that if the brake pad is observed with the naked eye, the thickness is only 1 At / 3, then we have to start thinking about replacing the brake pads. Of course, some models ca n’t see the thickness of the brake pads with the naked eye, so only the repair shop will ask the master to observe, and some vehicles also provide self-inspection functions, meters The disc will indicate the wear of the brake pads.

Secondly, according to the braking force, if you are struggling to brake on the road, you will always feel a soft feeling. You often need to press the brake deeper to achieve the previous braking effect. When you apply emergency braking, you will obviously feel the pedal. If the position is low, it may be that the brake pads have basically lost their friction. At this time, they must be replaced, otherwise, serious accidents may occur. In addition, the reduction of the braking effect will lead to an increase in the consumption of brake fluid, so it is important to check the condition of the brake fluid while replacing the brake pads. Of course, this method depends on your driving experience for many years.

Or brake pad alarm. If the brake pads have induction wires, a red alarm “Please check the brake pads” will appear in the general alarm. Then there is an icon, which is a circle surrounded by dotted brackets. Changing when the warning light is on is already quite dangerous. Because some of this warning system directly senses the thickness of the brake pads, others cause the warning lights to turn on only after the brake pads have been completely worn out and the brake fluid is extremely reduced.

Finally, listen to the sound. During the process of braking, if you hear the harsh noise of "iron grinding iron" at the brake disc, this indicates that the brake pads have shown signs of wear and even reached the friction limit. Need us to check and replace the brake pads.
