Brake enters the void, Omega A

Hello everyone, right at the beginning, I know it’s dangerous to keep driving the car and I don’t have to leave it. Do not drive it anymore I didn’t find anything suitable in the search. The following problem occurred yesterday at the Omega A Kombi BJ 92, I drove up to a crossroads and stopped, the brake I had kicked, because the road was slightly steep. Suddenly the brake pedal completely receded and the car rolled. I was down from the Peda In the first moment I thought I was stupid, that couldn’t be. I continued my drive and a few minutes later I stepped into the empty again with the brake, the second time he hit on it again normal, almost bit already poisonously braked. The whole thing happened to me up to home a total of 4 times Now stands autochen ignored in the yard. What could be the result of this? Neichtichtichtheit im Circulation? It drips but ni Somewhere and I think it’s funny that every time he kicks on it again he slows down again. If he goes on like this there are no new doors, then I weld handle to it and bring him to schrotti *stinksauerbin*
