I was driving and everyone stopped for the red light. My car was not stopping, so I turned to the right where there was grass. I hit 2 signs and was headed to an office building so I turned toward the left and the car stopped in a Ford Dealership lot. We were lucky and NO One got hurt, except the car. When the car was being repaired I asked the manager to check the brakes. They told me that they found air in the brake line and flushed it. The car I had for 1 year with only 5600 miles. The manager said that he did not know how the air got into the line especially since it was new with low mileage.
