Squeaking sound from wheels during rolling start/Brake Noise (merged)

I tried that on purpose but it still squeeks

 

Oh I understand.. but I did stop from going really fast too

 

Rick, did it come back or is it gone for good?

 

Toyota should really figure it out at least for our ear's sake

 

IMHO, owners should get over it. It is NO BIG DEAL!!!

 

FWIW, since Seattle has had rain, my squeak has disappeared.

You'd think the rust would be having a field day !

 

Ok, so I read ALL 13 pages of this post so far, and I'm surprised no one has mentioned the problem I'm having. I do hear the squeeking, but only when i REVERSE! It happens when i first turn on my car after it's been sitting a while, and reverse out of my parking spot. Once I put the car into drive, no more squeeking. Has anyone else had this problem?

 

I dropped my Prius off for its first servicing.. I mentioned my rattles and the squeaking.. I'll report what they come up with.

 

I hear it as well only in the early morning with cold brakes, it has nothing to do with overall external temperature. I had it on my previous car as well. No noise after braking once. I don't even notice it anymore and in any case the engine noise covers it during warm up phase after a few seconds I am driving. Never heard it with a warm car, that is, with warm brakes.

I think it is due to the last final brake one gives at the end of the drive, before setting it into park/turn off.

 

My Prius was in for its first service this weekend. They said they couldn't hear the squeak (BS!) and everything looked good for each brake.

I think it's a lost cause

 

Just picked up my Prius V from its first 5000 service and mentioned the squeek coming from my right rear wheel (for the last 3000 miles) and how the car has to be turned off for a few minutes to keep reproducing it. Sure cold weather and rain makes it happen more frequently.

To my surprise, they were able to reproduce it and in fact when I questioned about it, the tech acknowledged that a few other customers have reported the issue and that Toyota has told them to re-lubricate the brake system as the tech noted that the side I was having issues with was not properly lubricated. What you ask they lubricated? I don't have the report in front of me, but he told me they disassembled the break system, lubricated and out of all the cars reported with this issue, none have come back.

I will see if the fix actually worked when I pull out from work tonight as the car always exhibits the behavior when I leave and you can hear it in the parking garage for sure.

He said unless Toyota tells them otherwise, they won't do anything else for the scenario but re-lubricate.

 

It would be interesting to know what they lubricated.

 

So as not to leave you hanging, here are the notes from the invoice when I got my wheel squeeking fixed:

********************************
Concern - Customer hears a rotational squeak coming from the R.R. brake. Gets worse if there is moisture/rain. Started happening around 2k miles. Please inspect and repair as needed.

Cause - Verified noise from rear brakes, tech found lack of lubricant on rear brake support plate and shims.

Correction - Removed rear brakes--lubricated with brake grease, backing and support plate--shim kit as well. Re-installed and no longer making noise after repair.
********************************

As of my drive to work this morning and moving out of my garage, there is no more squeak. Hopefully this fixes the issue. If it comes back, I guess they can redo this again, but as I can hear this every day and have not heard it since, I hope this fix works for a long time.

I hope this helps all of you as I know how annoying the wheel squeak is and mine was very loud and happened after every time I restarted the car after being idle for more than a few minutes.

 

Well I think it's minor so possibly why it does not get mentioned. I notice mine each day does it for a little bit while backing out of the garage, down the driveway.

I did note though, that once driven and you back up later NO SQUEAK. So I suspect dampness, or something, but have no brake issues with my car at all.

So, I am not overly concerned at this point. Just will monitor.

Similar to PAKITT's response.

 

Well, I'm not at all surprised! I have been to the dealer on two occasions in the last 5 months and neither time could they hear anything. We are sooo screwed!

 

it would be interesting if it goes away in another 5000 miles, or possibly get worse ;-). If the squeak is not that bad, dont get too worked up, it will take a while for them to figure it out... usually it could be dust clogging support plate/shims. It happened to european Auris for quite a while, took them a while to fix ;-)

 

I had the same squeaking sound from one of the wheels dring rolling start from the very beginning. However, after a while it is completely gone now. Hope it doesn't come back.
