Which is NOT a common cause of brake fade?

• A. High temperatures
• B. Moisture in the brake fluid
• C. Worn brake rotors
• D. Incorrect brake pad material

Answer: (C)

Worn brake rotors do not typically lead to brake fade. Brake fade generally occurs when the brakes are subjected to excessive heat, causing a reduction in their performance. High temperatures can arise from prolonged or aggressive braking, leading to a loss of friction between the brake pads and rotors.

Moisture in brake fluid can contribute to brake fade because it lowers the boiling point of the fluid, which can lead to vapor formation under high heat conditions, causing a spongy feeling and decreased braking efficiency.

Incorrect brake pad material can also be a source of brake fade. Certain materials may not withstand high temperatures, thereby losing their grip and effectiveness when heated.

Worn rotors, while they can cause issues such as uneven wear and vibration, do not directly contribute to the phenomenon of brake fade itself, making it an option that does not fit the common causes of brake fade in the same way as the other factors.
