The brake vacuum is leaking and it makes the brake hard when the car is off, as soon as I start the car after pushing the brake hard enough, the brake pedal returns to its normal state. I am concerned that if something happens to the break while I am driving, this is very risky. I went to the dealer four times and they are always telling me that the car is normal but before it didn’t have this problem. So the problem is not confirmed by the dealer. Also I have another Audi a6 same model that doesn’t have this problem.
