When a braking system exhibits a smooth, shiny appearance on the brake pads or rotors, this is referred to as a “glazed” condition. This glazing occurs due to excessive heat buildup during braking, which causes the friction material to harden and develop a polished surface. Consequently, the coefficient of friction between the pads and rotors decreases significantly. An example is a vehicle experiencing reduced stopping power or exhibiting a squealing noise during brake application, both indicative of this condition.
The presence of this condition diminishes braking effectiveness, potentially increasing stopping distances and compromising safety. Understanding the causes, such as aggressive driving habits or the use of low-quality brake pads, is crucial for preventative maintenance. Historically, the development of improved friction materials and braking system designs has aimed to minimize the occurrence of this issue and enhance overall braking performance.
