14. A method for issuing an early warning about a malfunction of a brake of a vehicle, the method comprising:
monitoring sensor data during subsequent stages of a braking process, wherein the brake is configured to perform a braking process, and wherein the vehicle includes a sensor to generate the sensor data indicative of an actuation force of the brake;
detecting, based on the monitored sensor data, a potential malfunction of the brake; and
issuing a warning signal when the potential malfunction is detected;
wherein the detecting of the potential malfunction of the brake is based on a comparison of a progression of the sensor data with a characteristic, and
wherein the method further includes storing the sensor data, and updating the characteristic based on the stored sensor data.
