3/12/11 I was driving at 55 mph on state rt 104 in columbus ohio when I had to get on my brakes hevily to avoid hitting a van that was turning in front of me, the following car did not stop and collided with me forcing me into the van in front causing heavy damage to the rear vehicle and to mine . Immediately during the accident my brakes failed and I was unable to avoid hitting the van in front until I was able to think to put mine in park to stop the vehicle a few minutes later I tried my brakes again and they were o. K. I feel the antilock brakes failed either because I was into them or due to my vehicle being hit so hard from the rear. My vehicle is a 2008 Toyota Sienna van. The vehicle that hit me was a 1997 Honda civic the vehicle I hit was a Dodge caravan year unknown.
