The truck travels all year round, and the wear and tear of many accessories on the car is inevitable, and the brake pads are one of the wearing parts, which need to be inspected and replaced from time to time.

How to tell the truth?

2. Comparați dacă prețul este rezonabil. Prices on the market range from dozens to hundreds, and businesses in the sale are emphasizing the original factory, in addition to price differences, for quality differences, businesses are also well aware. The two can be said to be the exact same size and shape, but their prices are three times different. Therefore, a point of price, a point of goods, is indeed the standard for judging the quality of things, as long as it is lower than the market price, it must be inferior.

4. The friction coefficient of the friction coefficient is too high or too low will affect the brake performance, especially in the high-speed emergency braking, the friction coefficient is too low will appear insensitive, the friction coefficient is too high will appear tire lock fenomen. According to the SAE standard, the friction plate will choose the FF grade rating coefficient, that is, the friction rating coefficient is 0.35 ~ 0.45. In addition, according to the national standard, the appropriate working temperature of the friction sheet is 100 ~ 350 ° C, and the coefficient of friction will drop sharply when the inferior temperature reaches 250 ° C, and there is a failure.
It is said that the driver is a high-risk occupation, a heavy truck loads dozens of tons of cargo, the operation and the car is completely comparable, once an accident, the consequences are unimaginable.
