If the friction components of the braking system overheat because of continuous or excessive use, what is the consequence?

Question

DentroTest · Accepted Answer

Excessive or prolonged use of the service brake, especially when going down long slopes with a heavy vehicle, generates very high temperatures in the friction elements (discs, drums, pads and shoes). When they overheat, the friction coefficient drops sharply and braking effectiveness is lost: this is the effect known as fading, or brake fade. For this reason it is not true that heat increases braking capacity, since it rather degrades it, nor that nothing happens: friction materials have clear thermal operating limits.
