The present disclosure relates to a method for operating a vehicle brake system which includes the following steps: () determining a first wear value, which indicates wear of the friction lining of the vehicle brake, by taking into account at least one of the relevant parameters related to the operational history of the vehicle; () In dependence upon whether the first wear value meets a predetermined criterion, measuring the wear of the friction lining by moving the parking brake unit and by recording the curve of operating parameters of the parking brake unit while moving; () determining, based on the measurement, a second wear value, which indicates wear of the friction lining of the vehicle brake. The present disclosure also relates to a vehicle braking system, as well as a computer program and a control unit for implementing the method.
