1. A method of determining cumulative damage of an electric park brake system or an electromechanical brake system, the method comprising:
(a) estimating or measuring one or more brake forces based upon one or more parameters;
(b) determining a cycle for each of the one or more brake forces and associating each of the one or more brake forces with the cycle; and
(c) determining the cumulative damage of the electric park brake system or the electromechanical brake system based upon the cycle and the associated brake force; and
wherein a signal or warning is transmitted when the cumulative damage exceeds a threshold value.
