THE MAIN PERFORMANCE OF BRAKE PADS

The brake Diaphragm is our main product, what are the main properties of brake pads?

　　The performance of the same brake pad under different temperatures, different vehicle speeds, and different braking pressures is very different.

　　1. Braking performance: refers to the braking ability (friction coefficient) of the brake pads under the normal braking state (the braking temperature is relatively low).

　　2. Decay performance: In the road conditions such as downhill mountain roads, the brakes brake continuously and the temperature rises rapidly, and the brake disc may reach a temperature of 4, 500, or even 700 degrees Celsius. The braking capacity of the brake pads will become worse and the braking distance will increase. This phenomenon is called "recession", and we certainly hope that the smaller the recession rate, the better. The decline rate of high-quality brake pads is very small, and some even do not decline, while some fake and inferior products decline very seriously, and almost lose their braking ability at high temperatures.

　　3. Recovery performance: After the high temperature decayed brake pads, when the temperature drops, can the original braking performance be restored as soon as possible? This is also the importance of measuring the quality of brake pads

　　4. Brake pad wear: It is the wear of the brake pads when they are used. The braking effect depends on the formula and process of the friction material. For example, carbon fiber brake pads can be used for hundreds of thousands of kilometers without replacement. In addition to the wear of the brake itself, the wear of the brake pads should also be considered. During the braking process, the high-quality brake pads will form a protective film on the friction surface of the brake disc to reduce the wear of the brake disc, while the inferior brake pads contain a lot of hardpoints and impurities, which will pull out many grooves on the surface of the brake disc. , accelerate the wear of brake pads and brake discs.

　　5. Noise is also a very important indicator in today's advocating environmental protection. In fact, there are many factors that cause braking noise, and brake pads are only one of them. It is generally believed that if the hardness of the brake pads is too high, it is easy to generate noise.

　　6. Other performance indicators such as shear strength, hardness, compressibility, thermal expansion, water absorption, adhesion, etc.
