You are right gpar2000, I get exactly the same noise as you described and I get that every 3rd or 4th time I apply the brake and sometimes even while accelrating After reading this post and searching on internet , I am getting a feeling that this is normal but hard to belive that Toyota did not do anything to fix it. Every 3rd or 4th time should be atleast every 15th or 30th time..as I drive mostly in city and apply brakes quite frequently..

I hope toyota does something to fix this normal beaviour as it is annoying.
