It is the second GTI Edition 30 that has the same symptoms, years apart. At the racetrack, during a track day event, under hard braking sometimes I feel that the pedal goes suddenly all the way to the floor. The car is still braking even during that brief moment but it is really worrying to feel this during a high speed braking zone.
Does anyone have any idea what is wrong? I know how boiling brake fluid feels and it is not that. It feels like a leak in the master cylinder. Any piece of advice is gold
