Operating temperature will depend on many factors, first of all it is material from which pads are made. There are four basic types of shoes on the variety of the material used for their manufacture.
- Their composition is from 30 to 65% of the metal, usually iron powder, graphite and copper, mixed with inorganic components and specific friction modifier is added for a better connection of all components.
- The composition of these pads include fibers, are made from materials such as kevlar, glass, carbon components, high temperature resin and rubber. This type of pad is softer to detail. Give less noise, but the drawback is the poor braking in contact with moisture and rapid wear, also they create a lot of dust, which and as the result, ventilated discs starting to clog.
- Law-metal or completely metal
- Their cost is higher than others, but the quality is much better. The composition contains the same components as in the organic, but with the addition of steel or copper, for improved braking and heat. They are effective, but lead to an accelerated wear of the brake discs.
- Ceramic brake pads
- Ceramic brake pads are the last type of shoes and the most effective but also the most expensive. Braking quality is better than in others, resistant to high temperatures and do not lose their properties in the moisture. It is composed of ceramic fibers, various non-ferrous metals, for binding and sometimes a small percentage of metal. Ceramic ones are more forgiving to the brake discs, less heated and produce little dust in comparison with the classic pads.
