The vehicle has received all scheduled and regular maintenance. I was driving right around the speed limit of 50 mph. Traffic was stopped ahead, and I had plenty of time and space to stop. I pressed the brake pedal, but continued to coast. I pressed it harder, all the way to the floor for at least four seconds, and there was no resistance, no feel of the antilock brakes kicking in, no emergency braking to avoid a collision, and no braking or slowing whatsoever. I could not safely swerve out of my lane, as there was no shoulder on my left and traffic on my right, and so there was an accident. The vehicle is currently at the body shop, and I told Stare Farm about the brakes, but they have no intention of investigating it.
