There are many loss parts in the car. The brake pad is one of them. Under normal circumstances, when the thickness of the brake pad is worn to less than 5mm (1 / 3 of the thickness of the new brake pad), it should be replaced. The manufacturer of the brake pad manufacturing equipment tells you that although the limit thickness of the friction layer of the brake pad is 1.5mm, the brake pad is too important for driving safety. For the sake of safety, don't wait until the wear reaches the limit to replace, and don't wait until there is a sharp "iron grinding" sound to replace. Preventive replacement should be carried out in advance.
Generally qualified brake pads can be used for more than 60000 km under normal use, but there is an unavoidable problem for the actual loss of brake pads, that is, the normal driving habits will also have a great impact on the service life of brake pads. Some bad driving habits will aggravate the wear of the brake pads, such as the habitual quick acceleration and quick braking, whether the tire pressure is insufficient or not, whether the car deviates in a straight line or eats the tire or does not do four-wheel positioning, etc., so, the same brake pads can be used for a long time but also for a short time, and human factors can not be ignored.
When using a car, there are three simple driving habits that can extend the service life of the brake pads, which are simple but practical.
