A prediction system and a prediction method for at least one brake system component of a brake system of a vehicle by ascertaining value groups of in each case at least two different variables during at least one driver-induced and/or autonomous braking process of the vehicle, the at least two variables of the same value group are ascertained simultaneously and in a braking situation in which at least one of the variables lies outside its respective specified normal value range and/or a temporal derivative of at least one of the variables lies outside a quasi-static range respectively specified for the respective variable, and estimating, using the ascertained value groups, whether the occurrence of at least one functional impairment of at least the one brake system component of the brake system is probable at least during a specified prediction time interval.
