Brake Noise

[ahn22]

I purchased 2010 Prius 3weeks ago. I noticed a noise(squeak) Whenever I apply the brake at that time when I picked up my new car from dealership. So the next day I went to the Toyota service center and heard "Every Prius break system makes that noise and it is Normal".
Is it true?? The dealer said it comes from the hybrid system.... After three weeks driving I've come to doubt that every Prius owner can stand the squeak noise and Feeling. Is it really normal? Does everyone hear it?

I have never heard a squeak. When braking there is a noise that sounds something like a subway train braking (others have noted that too), but that's not an unpleasant sound, and I wouldn't describe it as a squeak or squeal.

The regenerative braking system makes a whine, similar to the motors on a subway. It isn't terribly loud or annoying, but it is obvious. There is also inverter switching noise, which is at a higher pitch, but still a whine.

If your squeal sounds like normal brake squeal, then your brakes may need to be cleaned. Forcing the Prius to do mechanical braking will clean off rust and dirt. Find an empty stretch of road, go up to 40 mph or so, shift into N and brake to slow down. Repeat a few times and your brakes will be shiny and clean.

The sound that I hear sounds like a low (meaning not very loud) metallic (tin-like?) noise, I mainly hear when only using regen brakes. If I really stop, or 'glide' without any regen, I do not hear anything. Even when I do hear it, it is usually only with the windows open.


From all I have seen read, and heard, this is normal for a Prius.

Without hearing the noise your explaining, it's hard to tell. It has a metallic rubbing sound, as someone said, similar to a subway car slowing...or in a rail yard? That sound is typically normal. But if your not used to it, it may seem odd, but get it checked if your concerned and let us know how you made out at the dealer.

On the dvd that comes with the car, there a section which will allow you to hear all the sounds which are normal with the Prius. Check it out and let us know if you can identify your sound on there.
