Understanding Brake Fade Resistance

What is Fade Resistance?

In the world of high-performance braking, fade resistance is evaluated based on two primary factors:

1. How high the temperature is before fade begins (the "Fade Point").
2. How minimal the drop in the coefficient of friction is once fade has started.

How Brake Fade Occurs

Fade occurs when the resins within the brake pad's friction material begin to vaporise above a specific temperature. This process creates a film of gas between the pad and the disc rotor, which acts to separate the two surfaces. This gas layer dramatically reduces the coefficient of friction, leading to that "wooden" or unresponsive pedal feel.

Street vs. Sports Performance

The difference between a standard commuter pad and a dedicated sports pad is most evident in their thermal limits:

• Stock Pads: Typically have a fade point of around 300°C to 350°C.
• Sports Pads: Designed with a fade point between 400°C and 700°C, depending on the specific compound and application.

Understanding the Fade Rate

The fade rate is a numerical value representing the change in the coefficient of friction before and after fade occurs. It is calculated as a percentage, assuming the pre-fade friction level is 100%.

Quality sports pads are engineered to maintain a friction level even after fading that is comparable to a stock pad’s performance before it fades. By researching and developing advanced resin components and fibrous materials, manufacturers ensure that your braking remains predictable even under extreme conditions.
