What causes brake fade?

Answer: A — Brakes overheating

When brakes overheat, the friction between the brake pads and rotor can decrease, resulting in a decrease in braking power. This is known as brake fade. Worn brake pads can also contribute to brake fade, as they are less effective at creating friction and stopping the vehicle. Low brake fluid can cause brakes to feel spongy and less responsive, but it is not a direct cause of brake fade. Poor brake adjustment can result in inconsistent braking, but it is not a direct cause of brake fade either. By eliminating the other options, it becomes clear that brakes overheating is the correct answer.
