Abstract-Disc brake is one of the modern technology in the braking system. It converts the motion of the vehicle wheel into heat by using friction between disc rotor and pads in order to retard the vehicle's velocity. When sudden brakes are applied, friction between disc and pad tremendously increases due to which heat is generated in this system. Heat generated due to friction induces high-temperature regions over the disc. Because of localized heating of disc surface, a thermal gradient is developed over disc surface which may plastically deform the disc. Due to overheating, hotspots generation and thermal judders phenomenon occurring on the disc, failure of the disc is witnessed in the form of cracks over disc surface. This results in a decrement of braking efficiency and an overall drop in braking performance. This paper draws attention to selective issues regarding the failure of brakes due to overheating and methods to reduce such kind of failure.
