I got a 1995 honda civic a couple days ago and I'm not much of a car person. But my brakes are strange. Its like the pedal goes all the way to the floor sometimes randomly. And I have to push it in 1 or 2 times before stopping. Its worse than when I got it too. Which was was 3 days ago. Now it happens at every other stop probably. It feels like when the brake fluid on my old car just leaked out quickly. It seems pretty unsafe like this. Also I somehow skidded the other day because I was pushing hard on the break when it was loose. I didn't even make the turn. Also what does having air in your break line mean? Thanks!
