Which statement about semi-metallic brake linings is true?

Brake fade happens when heat buildup reduces the friction between pad and rotor. Semi-metallic linings include metal fibers that conduct heat and help keep the friction material from breaking down at high temperatures, so they maintain friction better under heavy or repeated braking. Organic linings, being softer and resin-based, tend to glaze or degrade more quickly when overheated, leading to greater fade. That’s why the statement is true: semi-metallics are less prone to brake fade than organic linings. Keep in mind that while they resist fade, semi-metallic pads can be noisier and may wear rotors a bit faster. The other options imply the same or worse fade behavior, which doesn’t align with the enhanced heat handling of semi-metallic materials.
