How often to replace brake pads

Softening, hardening, etc. When it comes to the braking system, we have to talk about the car's brake pads, because the brake pads not only affect the car's braking performance, but are also a component that is easier for car owners to inspect and has a longer maintenance cycle. But many car owners still have doubts, what is the replacement cycle of brake pads, and when should they be replaced?

Brake pad composition

Brake pads are composed of friction material layer, heat insulation layer, adhesive layer, backing plate, etc. The brake pads push the backing plate through the brake cylinder to press the friction material of the brake pads against the brake disc for braking, so the quality of the friction pads is particularly important. Some brake pad friction materials are relatively hard and have poor braking effect but have a long service life. Some brake pad friction materials are relatively soft but have good braking performance. From this point, it can be seen that the life of the brake pad is directly related to the quality of the friction material.

Brake pad replacement cycle

Car owners may have some disputes about the replacement cycle of brake pads. The main reason is that the repair shop owner wants to extend the replacement cycle, and the repair shop wants to shorten the replacement cycle... Perhaps most car owners have encountered this situation. Car owners go to a 4S shop repair shop for maintenance. The people in the shop only look at the mileage of your car and immediately recommend you to replace the brake pads... Generally, car owners who do not understand cars may directly replace the brake pads. In fact, there are many times when the brake pads do not need to be replaced. Whether the brake pads need to be replaced is not only related to the mileage, but also the actual thickness of the brake pads.

When do brake pads need to be replaced?

In daily use of the car, car owners should pay more attention to the thickness of the brake pads. When the brake pads are worn to a visual inspection of 3mm, they need to be replaced. If the car owner does not have the habit of checking the vehicle, there is no problem, because there is an alarm sensor on the brake pad. When the brake pad is too thin, the brake pad sensor will alarm on the instrument panel. After the car owner confirms that the brake pad alarm is caused, don't be too panic and just drive to the 4S store to replace it.
