？ Let the
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. In the replacement process, some black-hearted businesses, because they want to seek violence, will place some fake and shoddy products on, not only the quality is not guaranteed, but also the serious situation will cause great danger to the driving safety of the所有者。 How to tell the truth?
3。外観を観察します。特に摩擦材料の割合の高品質、そして外観は色に満ちているように見えます。滑らかなタッチがあり、塗料から簡単にはなく、良い仕上がりになりません。 Informal in order to reduce costs, work at will, a large number of cheap metal debris will be used in the production, the color may be red, the surface or has occurred oxidation phenomenon, the red substance is the old saying rust.
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現象。 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.
ドライバーは高リスクの職業であり、重いトラックが数十トンの貨物を積み込んでいると言われています。操作と車は完全に匹敵します。良いものは、事故の可能性を最小限に抑えることができます。大多数のドライバーの安全のために、購入時に品質保証を選択する必要があります。
