I was traveling this past Tuesday, may 1st, and I notice a slight noise from the inside of my van when I had reached my destination. It happened when I applied my brakes but when I roll down my window I hadn't noticed any noise from the outside of the van. I was alone and did get out and I hadn't noticed anything in or around the front left tire. I had to travel another 1 and a half back home and by this time my car was making a horrible noise. I had a mechanic look at the car and informed me that the rotor was messed up and the brakes where metal to metal. I only have 29,000 miles on my van and he told me that this shouldn't be doing this until its due to a defect such as a bad caliper or the brakes where getting hung up. I called Toyota and they told me that they would correct this problem until I arrived and then they told me that this is normal for Toyota Sienna minivans. I am concerned that there is more to the problem because my brakes never squealed or squeaked and its only on the left side.
