Prius (Gen 3) :: 2012 - Squealing Heard From Rear Brakes
Jun 11, 2016
So, my 2012 Prius has 61,000 miles and I started hearing some terrible squealing from my rear brakes. This weekend, I decided to take the tires off and investigate. Turns out, that my rear pads were worn to metal.
I switched the pads with new ones. The rotor was still new and didn't need replacing. Torqued the caliper bolt to 25ft/lb and put it back together. However at the end, I forgot to put back on the two wire clips take keep the brake pads apart!
Do I need to put these clips on? I'm too lazy to take my tires off again.
Lesson learned: Turn clockwise and PUSH the rear piston at the same time to get it to go back in. Turning it alone does nothing.

Actually this started occurring at around 10k miles and I find it odd this would happen this early. It seems to happen more often on cold days and after a couple stops its gone. Why is this? I have heard of premature brake where on these cars and that braking power is biased towards the back under normal braking. I really do not how there is reduced brake dive using the brakes this way but its a vw. Is it just the stock pads that are bad?

I brought my prius v back to the dealer for the fourth time because of the groaning noise from the rear brakes. I was told that Toyota is aware of the problem and they are designing a new rear brake. They expect it to be ready for installation after January 1st, 2013. Let's hope it isn't too far after the first of the year.

I commute 35mi everyday. It's some stop and go, but at times it's a winding raceway up the valley. Yesterday about 45mins/25 miles into the drive I notice a squeak that's in rhythm with the speed of my car. Braking would dampen the noise, but it would return. I drove it over to the dealership where I work. They say they're booked, but they might have time to look at it in the afternoon between some other appointments. They call me about 2:30pm and say they drove the car around at 30mph, 40mph, and 50mph. No squeak. They say they'll take off the tires to look around. They call me again in 30minutes to say the car is ready, they didn't find anything. My drive home was quiet. Btw it was damp, but not raining yesterday morning. The afternoon was in the 80s and sunny.
This morning it was very damp and misting on the way to work. As I slowed for a toll booth the squeal reappeared and lasted for a few minutes as I got back up to speed. Then it disappeared. I had an idea it was a bad wheel bearing. I remembered reading that driving the car in circles clockwise and counter clockwise could identify a bad wheel bearing. I found an empty lot near the dealership and proceeded to drive in circles 25mph, but fairly tight. Not a peep out of the wheels except for the occasional squeal of the tires. Disappointed with my test, I drove right past the dealer quiet as a mouse.
Finally as I pulled into my work parking lot the squeal reappeared. I found an empty section of the lot and retested my circle hypothesis. Going in circles actually quieted the squeal in both directions. As the car returned to a straight course the squeal reappeared.

I have a horrendous squealing noise coming from one of my rear wheels. Sounds bad at low speeds, changes frequency to higher pitch when going faster. The sound isn't constant (some times nothing), other times loud as hell. Sometimes gets worse when turning, then nothing when straightened out. When breaking, sometimes the sound gets worse, then goes away. It doesn't sound like a bad wheel bearing (had one go before- more of a growly noise). This sound is too high pitched. Also, checked the brake pads (plenty of life left), and rotors are good too.

I have been doing my own brakes for years. I have had some that were not easy to keep from squealing but this one has me wanting to get rid of the car. We have a 2008 Dodge Magnum R/T package. Roughly 38K miles on the car. When the car reached around 10K miles the rear passenger wheel would squeal when you applied the brake. Rotor surface was smooth as glass. I took off the rear rotors only and had them turned. Problem went away for about 5K miles. Then the fronts started squealing.
I replaced the fronts because hte factory did not leave any material to be turned and noted that Dodge glued the pads to the calipers like they would never need to come off. Problem went away for a little while. Then it came back with a vengeance. I replaced the pad material on the fronts with ThermoQuiet pads from Raybestos. Problem is coming back again and now I cannot tell which end of the car it is even coming from because it it so loud. My wife drives this car very carefully. My thought is she is polishing the rotors too smooth and this is our source of noise.
We are at the point of squealing again and I am at my wits end with this. If I light foot it, no noise. If I stop like I think it should be stopped, not killing it, the noise is there. If I stop very quickly about 3 to 5 times in a row the noise is gone for a little while until the pads cool and then it is back even if I am on the same journey.

I have a 06 accent sedan and I have been having some issues with the back brakes that were just replaced prior to the motor vehicle being done the end of June. I had the brakes replaced and everything was working fine up until the middle of last week; now the brakes in the back are squealing like the warning plates are rubbing together again (loud high pitch squealing) what could be causing this...I took it back to where I had the brakes replaced and they did a check and said that it did not look like anything was wrong and they asked me when my front brakes were replaced, I told him they were replaced last August when I have a issues with a caliper freezing up and had to replace everything in the front (brakes, caliper etc). So long story short he said to keep driving and see if you can tell if the squealing is coming from the front or the back and come back when its happening or if you can determine which one it is..

The pads were replaced 5000 miles ago. Today the truck is acting hard to go, brakes are squealing, and I noticed a hot brake smell. I got home, grabbed a remote thermometer gun and the front rotors are 130 degrees, the back ones are 650 and 700 degrees! Super hot. I'm going to NAPA for new calipers and pads. I hope that fixes it.

99% sure it's time for brakes. Sounds like the wear indicators are squealing. I'll pop the tires off tomorrow and take a close look. Found a thread on here about doing brakes. Sounds pretty easy.

I'm the loudest Prius in CT right now. My brakes doing that loud scraping sound. Is it normal to need brakes this soon?

Is it my wheel bearing, rotors or brake pads?
How do I describe it... well it has this squealing noise and it's proportional to my speed.
Heard this while I had my windows rolled down.

I've been trying to pin point this golf ball rattle i hear from my passenger rear side of my car. I though it was the sway bar end links wearing out, so i changed those along with a pair of new rear struts as they were leaking.
I was still getting the that rattles when i drove on bumpy roads. I then though it was the sway bar bushings going out on me so i took the sway bar off to eliminate it all together.....WRONG AGAIN.
Ok, it must be something behind the bumper right? before i start pulling the bumper clips my spider man senses zoned in on the passenger rear wheel caliper that i had changed 6 months ago due to a rusted guide pin that i acquire while i was living in snow country New York.
I began rocking the caliper and to my surprise the damn thing was moving very loosely.
Time for some maintenance: Turned out that the lower guide pin on the 6 month old caliper was loose. Cleaned it up and tighten it with an Allen key applied some crc brake grease, installed new brake pads and hardware and that took care of that damn rattling.

Well I've had it with the low mph squealing of my brakes. I'm currently running the brembo 2bk 4 piston set up. I'm assuming it has race pads since it only squeals at low speeds. The pads are still good btw.
I do not track the car so I was thinking something in the middle pad wise. I was looking at the hawk hps street pads(they seem great with no noise) or the stoptech brake pads(pretty much the same as the hawks). They both will fit my brake setup.

I have a 1997 F150, 4X4. My mechanic says its time for new brakes and was curious if it would be worth possibly converting from drum brakes to disc brakes??
My mechanic has quoted me $300 to do the rear brakes, would it be worth the extra money to convert??? I really don't care for drum brakes. I have done a search on the internet and every time it brings up the issue with the parking brake.

2005 Prius. 190k miles. In San Diego, so hot summers...not Phoenix hot...90s. Mild winters. No san or salt on roads.
5k oil and filter regularly. Got new HV battery at 142k. Changed the coolant switching valve done . Coolant pump changed under Recall. Steering midshaft done. Front pads replaced at 120k. Rear shoes getting very close to replacement. Trans fluid change at 120k per manual and at 190k. Plugs at 120k.
Two new issues: when coasting in N, pretty quiet. Driving or coasting in D, there is a growl. At 35-40 mph, wind noise masks it. Frequency increases with speed. It isn't getting worse. And no better after the transaxle fluid change. Can't be CV or bearings because it only happens when in motion in D. No lights on MFD. I have not looked for codes.

Is there anything that can be done to stop my brakes from squealing all the time?

My brakes will not stop squealing and it is driving me nuts. I have the stock pads / rotors with 12k miles and three track days. To try and get ride of the noise I have:
- pulled wheels and cleaned all dust from wheels and calipers
- I have the TyrolSport caliper stiffening kit and pulled and greased front bolts
- re-bed in the pads and rotors
- when I had the wheels off and working on caliper bolts the pads looked like there was plenty of material left
I know people have complained about stock setup making noise in cold weather, but that cannot be the case here. It lonely happens at low speeds. What am I missing to get rid of the noise?

I am having some issues with the brakes on my Camry squealing when I don't have my foot on the brakes. Its an intermittent issue and it doesn't start making the noise until Ive been driving for 15 minutes usually and mostly does it at speeds above 45 mph. If I gently put my foot on the brake the noise stops and as soon as I take my foot off the brake it starts again.
Also, if I drive for more than 30 minutes without using the brakes the noise gradually gets quieter and then goes away. Last winter I had the passenger side rear inner brake pad get worn down to the metal. I think the caliper slides had stuck, because they were hard to push in and didn't spring back. I put some grease on them and didn't have any noise for about 9 months and just recently the noise came back.
Now, I didn't use actual caliper grease, I just used lithium grease and Ive read recently that you need to use caliper grease because over time lithium grease will dry up. I've checked all of the brake pads and none of them is down to the metal or even worn down to a point where the scratches would touch the brake rotor and cause a noise.
In fact, about a month ago I replaced the front pads and the noise was still there. Now, here's my question: do that sticking caliper pins on the rear caliper would cause this noise and that I simply need to grease the pins?
