Problems solved by technology

Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and its needle-like limiters can easily enter the lungs and stay there, causing irritation, which can eventually lead to the occurrence of lung cancer
But in addition to the health hazards, there is another important problem with asbestos brake pads
Because asbestos is heat-insulating, its thermal conductivity is particularly poor. After repeated use of the brakes, the heat will accumulate in the brake pads. After the brake pads become hot, their braking performance will change, and the same friction and braking force will be produced. More brakes will be required, and if the brake pads reach a certain level of heat, the brakes will fail

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile brake pad and a manufacturing method thereof. Background technique [0002] Earlier car brake pads were asbestos-type brake pads, but it is now found that asbestos has been confirmed by the medical profession to be a carcinogen. Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and its needle-like limiters can easily enter the lungs and stay there, causing irritation and eventually leading to the occurrence of lung cancer. But in addition to the health hazards, there is another important problem with asbestos brake pads. Because asbestos is heat-insulating, its thermal conductivity is particularly poor. After repeated use of the brakes, the heat will accumulate in the brake pads. After the brake pads become hot, their braking performance will change, and the same friction and braking force will be produced. More braking times will ...
