Abstract
An exemplary method for determining a remaining life expectancy of a brake component includes the steps of providing vehicle parameters that identify operating conditions of a vehicle, using the vehicle parameters to determine work done by a brake of the vehicle as brake work, using the brake work to determine brake rotor temperature, using the brake rotor temperature to determine a fatigue damage of the brake component, accumulating the fatigue damage to determine a cumulative fatigue damage of the brake component, and comparing the cumulative fatigue damage to a damage limit to provide an estimation of the remaining life expectancy of the brake component.
