The simulator demonstrates how repeated hard braking events raise pad and rotor temperature over time, how the coefficient of friction rises to a peak and then drops sharply once a threshold temperature is crossed, and how a driver's instinct to press harder in response to fade can create a self-reinforcing heat spiral rather than restoring stopping power.
Set the grade and length of a simulated descent or choose a repeated braking cycle, then adjust brake application intensity and duration to see how rotor and pad temperature accumulate over successive stops. Watch the live coefficient-of-friction-versus-temperature curve to see exactly when the pad crosses from its peak-grip region into the fade region, and observe how stopping distance changes as a result. Try adding simulated engine braking or switching to a higher-temperature pad compound to see how each mitigation shifts the fade threshold and changes the outcome.
Sliders for descent grade and length or number of repeated brake applications, brake pedal force/intensity, pad compound selection (standard versus high-temperature), an engine braking on/off toggle, and a rotor design selector (solid versus vented), with live readouts of pad surface temperature, current coefficient of friction, and resulting stopping distance.
On a sustained mountain descent, brakes alone can be asked to dissipate an amount of heat equivalent to the car's engine running at a substantial fraction of full power continuously for several minutes, which is why truck drivers are trained to descend in a low gear using engine braking rather than riding the brake pedal the whole way down.
