I tried breaking and was on a hill with a small incline stopping behind a car as a pedestrian was crossing. When I pushed on the breaks lightly the car didn't break. So I pushed harder as the car in front of me was a few feet. When I pressed harder on the breaks the car actually accelerated and hit the car in front of me. The car made a strange noise and the warning that I was close to another car flashed on but the breaks failed to work at all. I had my breaks checked about 2 months ago when I had the tires changes and they said they were fine for now and just to have them looked at next tire rotation to evaluate. I've nver had issues with my breaks and my car took some damage. It was pretty terrifying.
