A disc brake operates by the action of a frictional material pressed against the sides of a rotating disc by a caliper. The caliper applies pressure to the disc through the use of brake pads. The brake pads are made up of a frictional material such as ceramic, organic, or metallic. The material is chosen on the basis of the application for which it is intended.
Disc brakes are further classified based on the type of disc used. There are two main types of disc brakes: solid and vented. A solid disc brake consists of a plain circular disc that is bolted to the wheel hub. This type of brake is commonly used in low to medium-performance applications. It is known for its simplicity and low cost.
On the other hand, the vented brake disc is a more advanced type of disc brake. It consists of two circular discs that are separated by vanes. The vanes increase the surface area and provide better heat dissipation. Heat is generated during braking and must be dissipated for effective braking. The vented disc provides better cooling and is, therefore, recommended for high-performance applications.
Vented brake discs are commonly used on race cars, sports cars, and other high-performance vehicles. They provide better stopping power, better cooling, and longer life. The extra cooling capacity of the vented disc allows for a more aggressive driving style and faster speeds without the risk of brake fade.
In summary, disc brakes are an essential part of modern-day automobiles. They provide better stopping power, longer life, and are more reliable than drum brakes. Vented brake discs are a more advanced type of disc brake that is recommended for high-performance applications. They provide better cooling and are, therefore, suitable for more aggressive driving styles. If you need to upgrade your brakes, consider vented brake discs for the best performance.
