It is often used in harsh environments such as high temperature/ humidity/ dust and uneven piston spacing, which has a great chance of wear. 2. In normal use, the lining is in good condition if the disk surface is bright and in a mirror state. 3. If there are black friction marks on the surface of the disc, the disc can not be held in time, and the disc makes a sharp sound when the water brake is seen, it needs to be replaced with new lining and disc. 4. If the brakes cann t be held tightly in time, the brakes makes a strange sound, indicating that the brake disc and the pad are polluted by grease, so it is necessary to replace the brake disc and the pad together. 5. Semi- metal pads have direct and sensitive brake response. But the consumption is faster and the high temperature load capacity is weaker. It is suitable for riding. 6. It has stable performance and super high temperature load capacity after complete break- in, which is suitable for high intensity riding and various climatic conditions.
