Editing Brake fade (section)

==Causes of brake fade==
The reduction of friction termed brake fade is caused when the temperature reaches the "kneepoint" on the temperature-friction curve and gas builds up between disc and pad.<ref>https://www.delphiautoparts.com/resource-center/article/what-is-brake-fade-and-how-to-prevent-it#:~:text=Brake%20pad%20fade%3A&text=This%20new%20film%20causes%20the,the%20surface%20of%20the%20disc.</ref> All brake linings are cured under mechanical pressure following a heating and cooling curve backstroke, heating the friction material up to {{convert|450|F|C|abbr=on|disp=flip}} to "[[Curing (chemistry)|cure]]" (cross-link) the [[phenolic resin]] [[thermoset]] polymers: There is no melting of the binding resins, because phenolic resins are thermoset, not [[thermoplastic]]. In this form of fade, the brake pedal feels firm but there is reduced stopping ability. Fade can also be caused by the [[brake fluid]] boiling, with attendant release of compressible gases. In this type of fade, the brake pedal feels "spongy".<ref>{{Cite web |date=2022-11-28 |title=What is Brake Fade and What Causes It? |url=https://www.autozone.com/diy/brakes/what-is-brake-fade-and-what-causes-it |access-date=2024-11-07 |website= |language=en}}</ref><ref>{{Cite web |title=Welchen Zweck erfüllt die Bremsflüssigkeit? |url=https://www.autodoc.de/info/bremsflussigkeit-kontrolle-wechselintervalle-und-kosten |access-date=2024-11-07 |language=de}}</ref> This condition is worsened when there are contaminants in the fluid, such as water, which most types of brake fluids are prone to absorbing to varying degrees. For this reason [[brake bleeding|brake fluid replacement]] is standard maintenance.
