—There is no mileage and age limit for brake pad replacement. As far as the brake pads are concerned, under normal driving conditions, the service life of the front brake lining is 40,000-80,000 kilometers, and the service life of the rear brake lining is 80,000-120,000 kilometers. But it is also possible that this car can be used for 60,000 kilometers, and another car must be replaced after 40,000 kilometers.

—This depends on the specific circumstances of the model, vehicle weight, and driving habits of the owner. If you are driving on road conditions where traffic jams often occur, you will inevitably brake frequently, so that the wear of the brake linings will be greater. If you often drive on such road conditions, the frequency of replacement of the brake pads of the vehicle may be high. In addition, the life of the brake linings of vehicles driving on expressways for a long time is longer than that of driving on urban roads. Driving on mountain roads is shorter than that on flat roads, and the brake pads of trucks are longer than those of small cars. short lifespan.

—In fact, it is not possible to absolutely calculate the life of the car parts. Only regular inspections are required to determine whether to replace them according to the damage.

—It is reasonable to say that the brake pads need to be replaced when they are worn down to nearly one-third, because the brake pads are thinned by friction with the brake disc, and the friction will generate high heat, which will be heated through the heat conduction of the brake pads Brake fluid makes us feel that the braking torque is not enough to stop the car.

—In fact, some brake pads are equipped with mechanical alarms, and some high-end vehicles are equipped with electronic alarm lines. Two or four mechanical alarm brake pads are equipped with alarms. When the friction material is often worn to 2mm from the steel back of the brake pads When left or right, there will be harsh noises. When a luxury car or a high-end car wears to the electronic alarm, the vehicle trip computer will prompt an alarm icon to replace the brake pads. At this time, the brake pads must be replaced.
