brake fade

fadiga dos freios

This page is in English. Where a word has a checked translation, it appears after the English term.

Loss of braking power because the brakes have overheated.

Heat changes the lining and expands the drum, so the shoes grip less. Fade comes from using the brakes too much instead of the engine on a downgrade. Brakes out of adjustment make the others overheat.

Tested: what causes brake fade, how to avoid it on a long downgrade, and what adjustment has to do with it.
