Disc brakes are a type of braking system commonly used in vehicles. They consist of a flat, circular metal disc that rotates with the wheel. When the driver presses the brake pedal, hydraulic pressure forces brake pads against the disc, creating friction that slows down or stops the vehicle. This design allows for better heat dissipation, which helps prevent brake fade during heavy use. One of the main advantages of disc brakes is their effectiveness in wet conditions. Unlike drum brakes, which can trap water and reduce performance, disc brakes maintain consistent stopping power. They are also easier to inspect and replace, making them a popular choice for modern cars and motorcycles.
