How Many Types of Car Brake Pads Are There?
1 Answers
There are three types of car brake pads. They are semi-metallic brake pads, carbon fiber brake pads, and ceramic brake pads. Car brake pads, also known as car brake linings, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks within them withstand external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. Classification of car brake pads: Semi-metallic brake pads, which use metal fibers (coarse steel wool) instead of asbestos fibers. Other parts are mainly reinforced with materials such as glass fiber and aromatic polyester fiber. Their advantage is that they are inexpensive, but the disadvantage is that their heat resistance is not very good. Because metal conducts heat, they are prone to thermal fade and have a relatively short service life. Carbon fiber brake pads, which are widely used in the aerospace field. Their characteristics include strong thermal conductivity and extremely high temperature resistance. Even with prolonged continuous braking, they can ensure no brake failure. Additionally, carbon fiber brake pads have lower wear on both themselves and the brake discs compared to semi-metallic brake pads, which not only extends the lifespan of the brake pads but also prolongs the service life of the brake discs. Ceramic brake pads, which are not actually made of ceramic but are a mixture of ceramic fibers and other fiber materials. They achieve hardness, wear resistance, and reduced dust generation through organic binder curing. The advantages of ceramic brake pads are that they are relatively durable, have good heat dissipation, provide shorter braking distances, and offer relatively better resistance to thermal fade.
