| Description of the problem | 1. Events leading to the failure: my wife was traveling north on peebles rd in allison park, pa in our 2004 toyota, sienna. After my wife proceeded through the intersection with duncan avenue the driver of the vehicle in front of my wife suddenly stopped short and that person's brake lights did not come on. When my wife realized the situation she hit her brakes hard and the pedal went quickly to the floor providing no braking and resulting in my wife? S vehicle to hit the vehicle in front of her. While all vehicles were traveling well within the speed limit the damage was extensive as the vehicle in front of my wife was a ford explorer. 2. The failure, frequency, and consequences: i have tried to replicate this failure and can readily recreate it. In a safe environment i have tried to suddenly and dramatically hit the brakes and the pedal quickly goes right to the floor. Some fairly limited braking does occur during these attempted re-creations but it seems to be too little and delayed. My wife's vehicle was significantly damaged requiring $7,083. 61 in total repair cost (documentation is available). 3. While the crash was the first time for such a dramatic failure, our concerns of the softness of the braking system had been previously reported to a local toyota dealer and their response was "that is how those brakes are". So nothing has really been done to correct the failure and i believe all the parts in the braking system currently are original to the vehicle. |
