How to identify the pros and cons of brake pads
Now go to the market to buy brake pads, there are really all kinds of things, all of which can make you dazzled, and you don’t know what to choose and what is more suitable. In fact, when choosing brake pads, you must check a few key points:
1. Look at the product packaging and the certificate of conformity
The brake pads produced by regular manufacturers will definitely be clearly printed on the packaging, and the license number, specified friction coefficient, implementation standards and other data will be clearly marked. In good condition, whether the anti-counterfeiting logo and packaging logo are consistent with the logo on the brake pad, and whether the product model is consistent with the content of the certificate.
2. Is the price reasonable?
The price of brake pads in the market ranges from dozens to hundreds, but merchants claim to be original products in the products they sell. In addition to the price difference, merchants who sell fake and inferior products are well aware of the difference in quality.
3. Observe the appearance of the brake pads
Our original high-quality brake pads are very particular about the ratio of materials used in the friction materials of the brake pads, and the appearance looks full of color and luster. However, the irregular brake pads, in order to reduce the cost, are relatively rough in workmanship, and a large number of relatively cheap metal scraps are used in the production process. The color of the brake pads produced in this way may be reddish, and the surface has been oxidized and turned red. The material is rust as the saying goes.
4. Check the friction coefficient of the brake pads
If the friction coefficient of the brake pads is too high or too low, it will affect the braking performance, especially during emergency braking during high-speed driving. If the friction coefficient is too low, the braking will be insensitive, and the friction coefficient will be too high. It is easy to cause accidents. According to the SAE standard, the brake friction pads will use the FF rated coefficient, that is, the friction rated coefficient is 0.35 to 0.45.
