The disc brake is a relatively recent innovation in the field of braking technology. In order to slow down a vehicle, it uses friction between a disc rotor and pads to convert the kinetic energy of the wheel into heat. Brake disc and pad friction rises dramatically when applied suddenly, causing a great deal of heat to be produced. High-temperature zones are produced across the disc as a result of the frictional heat generated. The disc may undergo plastic deformation due to localised heating of its surface, which results in a temperature gradient throughout the disc's surface. Overheating, the creation of hotspots, and the occurrence of the thermal judders phenomena all contribute to the disc's eventual failure, which manifests as fractures across the disc's surface. As a consequence, there is a decline in braking efficiency and effectiveness. This article discusses a few specific problems with brake failure caused by overheating and offers solutions to those problems.
