Do I still have enough brake pads, or the brake disc is already broken

Hello together Does anyone have experience with changing the brake fluid at the Micra K13? I would like to work with overpressure on the brake fluid tank, but am not quite sure if this can be done and whether you can do it. In the service documents only the method is described with brake pedal pumping and opening ventilation nipples. In the service documents also the brake pedal is to be fully penetrated during the pumping. Actually you should rather avoid that or? Thank you [V] on Motor-Talk from the topic ‘Bremsflüssigkeit änder Micra K13’ transferred.]
