Tell you about a few ways to check their own brakes. First, look at the thickness of the brake pads, brake pads in the general use of the process, not after the election of friction will be increased from 1.5 cm thickness about thinning, if thinner than 0.5 centimeters when the owners need to be aware that this Basic can be replaced when the brake pads. General according to their degree of environmental considerations drive to replace the brake pads wear, almost 60,000 km replacement. Secondly, when the brakes listen to the sound, if there is the kind of two iron voice came on, indicating brake friction with brakes said it had arrived, brake pads and brake discs are subject to damage, brakes manufacturer, then We will need to be replaced. Usually if you hear this sound explanation brakes have been damaged, so it is recommended to have a car of a friend this morning, check and replace the brake pads, brake discs because of the higher prices. Asbestos is a natural mineral fiber, it has a higher heat resistance and mechanical strength, but also has a longer fiber length, good heat resistance, flexibility and dipping is also very good and can be made from textile processing or asbestos and asbestos cloth impregnated with adhesive tape. Short asbestos fibers and their cloth with fabric can be used as the base friction materials. More because of its lower price (cost), so soon replaced cotton and cotton became a major friction material based materials. 1905 asbestos brake band began to be applied, Qingdao brakes manufacturer, friction performance and service life, heat resistance and mechanical strength of their products have greatly improved. 1918, people with short asbestos fibers are mixed with asphalt made molded brake pads. Early 1920s began the industrial application of phenolic resin, Hebei brakes manufacturer, because of its heat resistance was significantly higher than rubber, brake pad manufacturers offer, it soon replaced the rubber, and become the major adhesive friction material agent material. Since the phenolic resin and a variety of other heat-resistant synthetic resin as compared to lower prices, so since then, asbestos - phenolic type friction materials are widely used in the world today.
