Asbestos material brake pads
Before the 1970s, brake pads contained a large amount of asbestos material, which has the characteristics of high temperature resistance, fire resistance, and strong friction. However, due to the various harms caused by the powder generated during the production and use of asbestos to the human body, it can easily lead to respiratory diseases and even cancer. Therefore, asbestos brake pads have been banned worldwide.
Cooling of brakes
Excessive temperature is the main cause of brake pad degradation, so cooling the brakes becomes particularly important. For disc brakes, cooling air should be blown directly towards the fixture. The main reason for the deterioration of brakes is due to the boiling of brake oil inside the fixture. If cooling air can be introduced into the fixture during driving through appropriate pipes or specially designed wheels. In addition, if the wheel itself has good heat dissipation effect, it can also share some of the heat from the disc and fixture. Drawing lines, drilling holes, or ventilated discs can maintain a stable braking effect and avoid the sliding effect caused by high-temperature iron filings between brake pads and discs, effectively ensuring braking force.
