Well, almost none. Yesterday, I started off for work in my 2008 Passion. When I got to the bottom of the hill on our driveway, I hit the brakes to stop and the pedal went slowly down all the way to the floor!. The car slowed enough so that, with the help of the emergency brake, I was able to stop. It turned out that the cause was that one of the lines running under the car had deteriorated and was leaking. I had a new line fabricated and now all is well. So, just a cautionary tale to all of us driving the older smarts, the brake lines can wear out.
