The price of brake pads varies according to different models, materials, and brands. At present, the main materials used for brake pads are asbestos, high-carbon fiber, semi-metal and ceramics. Among them, asbestos brake pads have been eliminated. At present, the most common ones are semi-metallic and ceramic.Semi-metallicThe price is relatively affordable, mostly as long asDozens of dollars, one set is only a hundred dollars, Mostly used for ordinary cars, relatively speakingCeramicWill be better than metal, wear resistance and high temperature resistance, good thermal stability, fast heat dissipation, higher friction coefficient, but the price is more expensive, generally required300About RMB, one set is about 600-800about, More used in mid-to-high-end models.
The replacement of the brake pads requires disassembly of the tires, which is time-consuming and labor-intensive. It is recommended to go to the store to replace it. Of course, a certain fee must be paid.Generally charge50-100Working hours cost around RMB, Including replacement of brake pads andBrake FluidRaises.
How to judge whether the brake pads need to be replaced
One, look at the thickness
Generally, the thickness of a new brake pad is about 1.5 cm. If it is worn to one-third, that is, when the thickness is less than 5 mm, it is recommended to replace it in time;
Second, listen to the sound
If there is a metal friction sound when braking, it may be that the brake pads are worn to the lowest thickness, and the limit marks on both sides of the brake pads touch and rub and the brake discs make abnormal noises, and need to be replaced in time;
Three, look at the tips
Some models have brake wear warnings. If the brake pads are worn too much, the sensing wire will touch the brake discs, which will cause the resistance to change, which will generate electric current. If a signal is detected, there will be a brake pad warning light on the dashboard.
Four, by feeling
If you feel that the brake pedal feels light, or if you feel that the brakes are difficult to stop, it indicates that the brake pads are severely worn and the thickness is insufficient, and they need to be replaced in time.
Under normal driving conditions, the front and rear brake pads are different in the replacement cycle. Compared with the rear brake pads, the front brake pads will receive a greater braking force, often wear more and have a shorter service life. Generally, it needs to be replaced at about 30,000 to 50,000 kilometers; the brake pads bear less braking force and can be used for longer. Generally, they only need to be replaced for 60,000 to 100,000 kilometers.
