Compared with organic linings, semi-metallic linings are less prone to brake fade.

Brake fade happens when the friction material and brakes overheat, causing the friction coefficient to drop and stopping power to decrease. The material’s ability to handle heat is what determines fade resistance. Semi-metallic linings include metal fibers that conduct heat well and withstand higher temperatures before their friction properties degrade. This means they maintain consistent friction under heavy or repeated braking, so they are less prone to fade than organic linings, which can break down or glaze at elevated temperatures due to poorer heat transfer and binder degradation. While organic pads are often quieter and gentler on rotors, they fade more easily under heavy braking. Thus, semi-metallic linings are better at resisting brake fade.
