Prius (2004-09) :: 2007 - Suspension Squeaking Noise While Applying Brake
Nov 20, 2012
It's a 07 prius with 65k miles. I realized that it is making this squeaking noise while going over bumps "ONLY" when the brakes are applied.
I have 2 toyota dealerships checked. 1st dealer said no noise and 2nd dealer also said no noise... then, i requested to drive with the mechanic and he somehow heard the noise while I am in the car.
I posted a youtube video w/ iphone video if you feel like hearing the noise...

2005 F-250 6.0 4x4. After about 50,000 miles on my original brakes, they started to make a squealing noise when applying moderate brake pressure and slowing down around 30mph-0mph. It only happens after Ive driven the truck about 30 mins. It must be warmed up. After 100,000 I decided to change the brakes.....they had plenty of life left on them, but I changed them anyway. I put on new rotors and pads and calipers in the front because one was hanging.
After about 10,000 miles, the exact same squeal has returned. With the windows down, its loud enough to physically hurt your ears if you are next to a car and the sound can bounce back into the cab. It sounds terrible. I thought it was the front brakes, so I took them apart this weekend to put in some Disc Brake Quiet. They pads look great, plenty left, the rotors look great, no grooves. Everything is tight. I relubed pins and brackets and clips. Today...same squeal still. I am at a complete loss here. It is some sort of harmonic squeal and the only thing I can figure is that the rears are the culprit. I have a drivers rear caliper that will hang and stick if you drive it really hard, so I am considering replacing the rear calipers too and do the disc brake quiet treatment there as well. Im not confident this will solve the problem.
Like I said, its so loud you can't drive with the windows down. Its a piercing squeal. Is there anything else that I can check? I can't imagine others don't do this. Its so loud and pronounced that it must be some sort of design flaw or something.

Looking for a suspension diagram that can be shared for this model? I need to fix the squeaking noise from front passenger side and would like to have an overview pic of the suspension system.

I always apply my parking brake whether im parked on an incline or not. Sometimes if I disengage the parking brake, and set my car in Drive on a flat surface, my car does not advance (I'm not pressing the gas). This tells me that my parking brake is sticking! If I apply the gas slowly, I hear the brakes "clunk" off and I finally get going.

My suspension has been creaking even when I get in the car. I'm not even that heavy (about 150 lbs). The ride feels the same as it has before, but I also notice squeaking when going over bumps. This mainly happens in the rear shocks. How to fix it?

I had been hearing bang noise from my front suspension at certain times like when reversing car and applying brakes. It was happening since I bought my car and every time I have complained about it to local VW service guys, I was told by them that they cannot replicate the noise so there is nothing wrong. I even told them to have a look at front suspension bushings but again they said everything is fine.
Last week I went for 45.000KM Service and I complained about the same issue again and luckily this time service advisor heard the noise himself. Next day, they called me to inform that my front lower arm bushings needs to be replaced, front brake pads and discs, and front wheel bearings as well. In my response I told them that bushings were bad for long time and no one figured it out earlier and due to this my front brake discs had abnormal wear along with the wheel bearings.
I am still trying to relate that it is technically possible for brake discs at least to wear off earlier if the suspension bushings are bad as when you apply brakes, the brake discs are stressed heavily as the bushing are not absorbing any stress.
I would like to have thoughts on this matter. Just let me know if my understanding is correct or it does not makes any sense and technically would not be proved.
Just to let you know that it is 3.2 4motion model. My driving is average within 120 KM speed and never hit any potholes etc. Plus my brake pads indicator never went on.

Looking for a fix for the annoying squeaking noise often happening when depressing the brake pedal?
Dealer "bled" the brake actuator...did not work, said I need new actuators for 2.5k.... 2007 LS 460L ....

I just purchased a LS 460 2007, 64k miles. The brake when apply squeal, but not all the time when the break is applied. 5 times out of 10 times when you apply the break when driving the car for more than 20 minutes it start to squeal. It does not squeal when you first drive in the morning, but after driving more than 20 minutes, when you apply the brake - it will squeal on and off during various application of the break. Does the LS460 have brake indicator that would squeal all the time when you need new break? I am not sure what the sign that LS460 would need new break and rotor.....

My right front disc brake started making a squeaking noise at about 50,000 miles when I applied the brakes. It was on and off at first but became more frequent. It wasn't a grinding noise and it wasn't the sensors for a low pad. I changed the pads and after about 2 weeks I started getting a grinding noise when I'd apply the brakes. I checked the pads and they were fine. After a few months I replaced the pads, grinding happened again after a few weeks of wear. Within the next few months I replaced the pads again, each time trying different types. Had the rotors turned recently and again, new pads. The grinding is gone but after a few weeks the brake makes a chirping sound now when applied. They work fine in stopping the car.

When parking on an incline, say my driveway which is pretty steep, I engage my emergency brake. When I release the brake I get a creaking noise as I put it in reverse to back out of the driveway.Two questions is using the emergency brake really going to keep my car from rolling back down the driveway and does the creaking noise mean the emergency or rear brakes are being stressed by holding the car in an incline for several hours each day?
I really worry some days I am going to walk outside and my car will be in the neighbor's yard.

Here's the story, noise first appeared while accelerating to merge onto highways and then applying gentle braking. Sounded like "seagulls". Not my description. To me it sounded like a rubbing pulsating noise. Would not go away unless you came to a full stop. Then would appear again every other time you entered highway at, say, 85 and applied brakes to slow down to 75-80.
The kicker is, that was 35+k miles ago. Annoying, but three different dealerships never found anything and the service techs always made big eyes once you mentioned 85+ mph. "Oh, we can't legally replicate that"
Fast forward to now (meanwhile rotors changed, pads, tires) - the noise seems to appear randomly at lower speeds. It is also quieter (barely noticeable above 65).
Example from today - left dealership sporting new tires and a fresh proper 4-wheel alignment.
After accelerating to ~50 noticed the sound. Couple miles down the road stopped, made a U-turn - sound gone. Could not replicate for a while. Then had it twice on "straight and level" segments, seemingly random. On cruise control at 55 (hear it the best at that speed) sounds stay the same regardless of rpm (6-5-4 gear - no changes). Pulsating gets quicker-slower with speed. Very gently decelerated to 25 - noise went away completely, pedal to the metal back to 60 - no noise.
I'm at a complete loss as for what it can be. Turning makes no impact, no play on bearings (and I'm pretty sure those would have died long ago if it was them), rotors changed with zero impact, tires too.
Changes over time - got quieter and started to appear at lower speeds.
All stock except for H&R Sport springs on stock shocks. 88000 miles

It feels a strange noise like a shutter closes around Gear Nob/Handle while applying brake and the brake pedal is half pushed, approximately;
Even the car is in Parking Position and you push brake pedal, it half way pushed and Tick/Click noise like a shutter closing sound and then goes.
It quite hear able noise and coming from some time now.

I have a 2006 Toyota Highlander Hybrid 4WD. Whenever I apply the brake pedal past a certain point, I hear some sort of clunking type of noise from the front of the car. The noise can be done when braking hard, or even if I am at a stop and just press the pedal down hard. It sounds bad but I have not noticed any issues in braking performance. Everything is stock, brake pads have 60-70% as of my last serving. What this is and if I need to be concerned?

Just hit 225k with my 2004 Prius about a week ago. I passed inspection without replacing the (slightly) cracked rubber bushings for now, but what worries me is the cracks and a slight hole (it has not rusted completely through). Pictures attached. Should I do anything about this, and if so what?
Also, I've noticed that when I let go of the brake pedal, especially after a medium to the hard stop, I hear a squeaking... what's the cause for that? I know the front rotors have a bit of rust on the edges, but not sure if that's the cause... it seems to come from the back.
Other than that, the only other noise I've noticed is a slight clacking/tapping when the A/C is on, usually in hotter weather. The only thing I needed to pass inspection was to replace the muffler after a year and 1/2 ago, the last non-OEM part they put in at another shop was junk and rusted through pretty badly leaving a hole that was leaking. Ended up getting it replaced at the dealer with the OEM part this time...

Noticed suspension squeaks in C? Seems like I have one that is on the left side of the car when I leave early morning. It seems to subside as the outdoor temperature climbs.

This morning I was driving my 08 Lexus RX350 in fresh snow in Boston area. When I applied brake I noticed the wheel slipping/sliding and I heard brake noise (some sort of cracking noise - I don't know how to define that sound :-). It was fresh snow, may be an inch or two and I was driving around 10 miles. I have to pound on the brakes and it took few seconds before it stopped and I narrowly avoid hitting the suv in front of me.
I was driving with all season tires and ECT snow mode was not on during that time. Could that be a problem?
A week back I replaced the rear brake pads (akebono ceramic) & rotors (raybestos) at a local garage. Will it be a problem with the way it is replaced? or will there be any issue with ABS?

Rear end Suspension noise, '13 Santa Fe Sport 2.0T? I purchased a new '13 Santa Fe Sport 2.0T in Sept. 2013. Shortly after I noticed the rear end of the car creaks/squeaks when the suspension compresses thru it's travel. This happens when driving over tall speed bumps at 2-3mph or into/out of steep driveways at 2-3mph. Rear end noise/squeak at anytime?

So I have a 2004 Jetta 1.8t. Recently I noticed an issue with the brakes. It is a rare occurrence that this issue happens. Maybe 1 out 6 times I slowly stop the brake pedal seems to put pressure back against me applying brake pressure and makes somewhat of a grinding noise and the brakes don't seem to grab as well. But a split second later the brakes return to normal and grab as expected. Could it possibly be air in the brake lines or something totally different?
- Front brakes are in excellent condition.
- Just replaced the driver side front abs sensor and put new rear brakes and rotors on.

We have an 07 Jeep Compass, 2.4L, 4WD. About 3 months ago we started to get a creaking/squeaking noise out of the rear suspension. First time I looked at it I found a lot of rust on the calipers and rotors, so new calipers, rotors and pads. Got quieter for a week or so, then it started again. Put the rear up on jack stands and pulled the wheels again. Used a 4' pipe to move the suspension up and done. Had a little bit of noise, but I could not pinpoint the source. Soaked all the bushings with light weight oil and put it back on the road.
A little better for a day or so, but still creaking. Had a problem with one of the new pads (the latest friction material, no abestos, no copper), so back on the stands and change the brakes again. Same thing, quieter for a day or so, then back to creaking. It does this at slow speeds in parking lots. Don't really hear it on the highway. Took it to a dealer for state inspection and told them find the squeak. Claimed they could not hear it.
My daughter drove the mechanic around, no noise. 5 miles after it left the dealer it is back. There is a TSB for parking brake cables with a boot failure. Checked our over the weekend and boots are good, cables are not rubbing. It seems if you fully extend the suspension by jacking it up, that makes it better for a day or so, then its back. Sprayed every joint with Lithium grease last time.

2010 VW Passat - Sedan
See the attached videos. The first one (night time) was made before I took the car to the dealer the first time. Dealer said that I was going too fast over the speed bumps, so I made another video (daytime) showing the speed (10-13 mph). Both times you can hear a squeaking noise coming from the front that I just started hearing last week. The car has only 23,000 miles on it. I bought it brand new back in September of 2010. I don't know what to do because the dealer (of course) says that they checked everything and there is nothing wrong with the car.
What was the cause of it. I can take it to a mechanic and check it myself and then bring it to VW for repairs and telling them exactly what's wrong and why.
