Disk brakes are a type of braking system commonly used in vehicles, consisting of a metal rotor attached to a wheel and a stationary caliper that contains brake pads. When the brakes are applied, hydraulic pressure forces the brake pads against the rotating rotor, creating friction and slowing down the vehicle. Research in disk brakes focuses on improving their performance, durability, and efficiency, as well as reducing noise, vibration, and harshness during braking. This research includes developing advanced materials for the brake pads and rotors, optimizing the design and construction of the brake system, and enhancing the overall braking performance and safety of vehicles. Additionally, research is also conducted on the impact of environmental factors, such as temperature and humidity, on the performance of disk brakes.
