What is the definition of brake fade?

The definition of brake fade refers specifically to the reduction in stopping power that occurs after sustained or repeated braking. This phenomenon is typically due to the overheating of the brake components, such as brake pads and rotors, which leads to a decrease in their effectiveness. When brakes are applied continuously, especially in high-stress situations like a steep descent or frequent stopping in emergency response scenarios, the friction material can become too hot, which allows for a decrease in friction and consequently reduces the vehicle's ability to stop effectively. This is crucial for emergency response drivers to understand, as it impacts their ability to brake safely and maintain control of the vehicle under demanding conditions.

In understanding this concept, it is important for drivers to recognize the signs of brake fade and implement techniques to manage it, such as using engine braking or avoiding prolonged braking when possible.
