Upon trying to stop at a stop sign my son was unable to stop in time and rolled into the roadway which caused a collision with another vehicle. He depressed the brakes and clearly heard a grinding noise and never felt the pumping feeling under his foot for the antilock breaks. He thought he couldnt stop due to ice on the roadway, but have since seen the brake recall on my vehicle. The accident caused the vehicle to become a total loss. The witnesses said my son stopped at the stop sing and pulled into the roadway in front of car going 50mph. That could not have happened by the angle of the car at the time of the accident. Had he stopped like the 'witnesses" said, he would have entered the roadway a couple second later and then become t-boned by the other car. He was hit on the rear quarterfinal coinciding with my sons story he could not stop. My son has held to his story that he tried to stop and the car would not stop. I have felt on occasion since Dec my brakes feeling a little off at times but never on a consistant basis to get it looked at. My vehicle had a small leakage in Dec which we could not locate and it never occurred since. We checked the brake fluid and all fluids routinely since. Never seen the leak since. I also put four brand new tires on my vehicle two days prior to the accident. It does appear in the photos after the accident there were new parts on the wheel in the area of the brakes. I only owned this vehicle for 9 months prior to this incident.
