I have a 2001 Sienna, it was making a noise when I made a left turn, at very slow speeds (20 mph and under). After checking I found that the brake shims on the back of the pads had moved and while making a slow left turn would make a cherping / sqeeking sound. Again, I only heard this at low speeds, I removed the shims from the back of the pads and purchased a silicone spray backing compound (blue in color from a local auto parts store)and applied it, let it dry and reassembled. I left the shims off, according to instructions on can and the noise is now gone, (quiter than ever) has worked well for about six months, no problems.
