Asbestos brake pads

Since the beginning, asbestos has been used as a reinforcement material for brake pads. Asbestos fiber has high strength and high temperature resistance, so it can meet the requirements of brake pads and clutch plates and pads. This kind of fiber has strong tensile capacity, can even match with advanced steel, and can withstand high temperatures of 316°C. What's more important is that asbestos is relatively inexpensive. It is extracted from amphibole ore, which has been found in many countries.

In asbestos-based brake pads, asbestos accounts for 40-60%, but people now find that most asbestos are potentially harmful. Asbestos has been confirmed by the medical community as a carcinogen, and its needle-like fibers easily enter the lungs. Staying, causing irritation, can eventually lead to the occurrence of lung cancer, but the latent period of this condition can be as long as 15 to 30 years, so people often do not recognize the hazard caused by asbestos.
