The braking function of brake pads relies on the friction between braking components, which forces the components to brake. As a component of motor equipment and vehicles, brake systems are among the most critical safety components in motor equipment and vehicles.
I. Formulation System
Brake pads, as a braking material, are actually a composite material made from various minerals and mineral fibers through polymerization. Different vehicle models and geographical locations have different requirements for brake material products.
The coefficient of friction is the most fundamental parameter of braking materials, determining the braking performance of brake pads. National regulations strictly require manufacturers to indicate the coefficient of friction of the brake pads on the product packaging. A coefficient of friction that is too high will generate significant impact and vibration during braking, while a coefficient that is too low will result in excessively long braking distances; both can lead to traffic accidents. Therefore, it is essential to strictly control fluctuations in the coefficient of friction.
II. Service life and features
Many drivers are very concerned about how many kilometers their brake pads will last. However, this is a very unscientific way of calculating brake pad wear. This is because brake pad wear is greatly affected by road conditions and driving habits (frequent braking on poor road conditions). The wear and tear differs significantly between mountainous and plain areas, and the wear and tear of brake pads also differs between drivers with short driving experience and those with extensive experience.
Branded ceramic-modified brake pads can extend the service life of car brakes to 60,000 to 90,000 kilometers in flat areas, while also extending the lifespan of brake discs (hubs) by 1.5 to 2 times. This is because ceramic-modified brake pads utilize a sliding friction method that differs from the traditional shear friction method. Sliding friction does not scratch the brake disc (hub), and a continuous thin carbon film is formed during use. The disc (hub) surface is smooth as a mirror, without friction grooves, resulting in a smoother surface, increased friction area, more stable friction, and stronger braking performance. In contrast, traditional brake pads develop friction grooves during use and slip when braking in water. The reduced wear resistance and braking effect of the brake material come at the cost of a shorter brake disc (hub) lifespan.
