It is understood that there are about 300 domestic brake pad enterprises, and the annual demand for brake pads in the country is about 400 million pieces. The sales of regular enterprises account for about 280 million pieces, and other products are produced by informal enterprises. Relevant experts remind car lovers that 30% of the brake pads have problems, do not buy cheap and inferior brake pads, and risk your life!

According to the data, automobile brake linings, commonly known as brake pads, are an important safety part of the automobile braking system. If you accidentally choose inferior products, it is tantamount to planting a time bomb for yourself. However, there are many counterfeit and shoddy products in such a life-threatening auto parts.

Poor quality brake pads are popular

   
Automobile brake pads are divided into genuine and auxiliary factories, genuine and fake products, etc. When consumers buy brake pads by themselves, they often cannot accurately identify the quality of the brake pads. Brake pads are frequently replaced parts of automobiles. Some car owners only want to buy cheap price, and do not pay attention to quality, which is also one of the important reasons for the entry of inferior brake pads into the market.

Inferior brake pads are sold with name-brand labels. The retail price difference between counterfeit parts and genuine parts can reach up to 10 times, and a good pair of brake pads can generally be used for one to one and a half years. Unbranded brake pads of poor quality, worn out after three months, must be replaced, which not only increases expenses, but also easily leads to traffic safety accidents.

Exploiting policy loopholes

Car owners do not understand some hard standards for brake pads. When the car needs emergency braking during high-speed driving, the brake will be insensitive because the friction coefficient is too low, or the friction coefficient will be too high, and the phenomenon of locking will occur, causing the vehicle to slip and roll over. It is said that the accident is not due to improper operation, or it has been used for too long, and it has nothing to do with the quality of the brake pads.

Due to the complex use of vehicles, the state does not enforce the number of kilometers for the life of the brake pads. Some businesses seize this point and eat "policy meals". In fact, according to the national standard, the adaptable temperature of brake pads is 100℃-350℃. But for many inferior brake pads, when the temperature reaches 250 ℃, the brake will fail completely. In addition, the country also has standardized quality standards for the durability of automobile brake pads. For example, for disc brake calipers and brake pads, the standard stipulates that when the hydraulic pressure is 7Mpa, its durability should be able to brake 500,000 times at room temperature + high temperature? Move more than 45,000 times.

 

Price-performance ratio

   
For the purpose of profit, dealers take advantage of the lack of professional knowledge of ordinary users, and most of them recommend ordinary products with low quality, low price and high profit, or even inferior products.

   
The quality requirements of the supporting products are very strict, and the international quality standards are adopted. They have passed strict quality tests before leaving the factory. They are the "top" products in the automobile brake pads. The ordinary brake pad products are processed according to their domestic quality standards, and the standard parameters are lower than the international standards. At present, the supporting products include TEXTAR, MINTEX, FERODO, ACDelco brand brake pads, etc. You can decline the products that the dealer recommends to you that you do not understand. For normal driving vehicles, the service life of the front brake pads is 30,000 kilometers, and the service life of the rear brake pads is 120,000 kilometers. If the original brake pads are used, especially the supporting products, there will be no related safety issues during this period. accident.

   
Who decides the replacement cycle

   
The thickness of the disc brake pads can be checked by stepping on the brake plate, while the thickness of the brake pads on the drum brake pads must be checked by pulling the pads out of the brake. Whether it's the pads on disc brakes or the pads on drum brakes, the manufacturer specifies a thickness of no less than 1.2mm, before or after 1.2mm, the pads wear and peel faster. Businesses often require car owners to check the brake pads frequently, and the shorter the replacement cycle, the better.

   
In daily use, ordinary brake pads should be checked after 25,000 kilometers, and the replacement time should be determined according to the specific wear conditions. When installing new brake pads, the inside and outside should be distinguished, and the friction surface of the brake pads should be facing the brake disc to make the disc fit properly. Install the accessories and tighten the clamp body. Before tightening the pliers, use a special tool to push the plug on the pliers back into place so that the pliers can be installed in place. If you need to replace the brake pads on the drum brake, it is recommended to go to a professional repair shop to ask professionals to operate, so as to avoid errors.
