Why are ceramic compounds used for brake pads?

Ceramic compounds are chosen for brake pads primarily due to their excellent heat resistance and low noise characteristics. The ability of ceramic materials to withstand high temperatures without degrading is crucial in maintaining braking performance, especially during heavy or repeated braking situations. This thermal stability helps prevent brake fade, which can occur when brakes overheat.

Furthermore, ceramic brake pads are designed to produce minimal noise when in use. The formulation of these pads includes materials that dampen vibrations, resulting in quieter operations compared to some other brake pad types. This feature is particularly valued in consumer vehicle markets, where noise reduction contributes to a more pleasant driving experience.

The other options present misconceptions about ceramic compounds. While they may not represent the most affordable option, and quick wear rates do not align with their typical performance characteristics, their weight is not a defining factor in their design for use in brake systems. Their balance of performance, noise reduction, and durability makes them a preferred choice in various automotive applications.
