A method of operating a brake-retract system during a regenerative braking event begins with monitoring an amount of regenerative braking achieved. A set point threshold is linearly ramped from a first threshold to a max regeneration capacity if the amount of regenerative braking achieved exceeds a second threshold. The second threshold is less than the first threshold, and the first threshold is less than the max regeneration capacity. The max regeneration capacity is representative of a maximum amount of regenerative braking capable of being produced. A friction element is transitioned from a first, retracted-state to a second, ready-state if the amount of regenerative braking achieved exceeds the set point threshold.
