Porsche - Cayenne :: Brakes Grinding Sound While Stopping The Car
Jan 30, 2015
I purchased front brakes and rotors from O'Reilly Auto Parts, for my 2006 Porsche Cayenne. The brakes were grinding while stopping the car, so I went to O'Reilly and talked to them about the problem. They suggested that I get different pads. I ordered different brake pads, installed them and returned the others. Now the second round of pads are making that grinding sound again while stopping the car. I checked the rotors and they seem to be fine.Is there special pads that will not make that grinding sound? If so, where is a good place to get them from?

2008 Passat Komfort Wagon with 34,500 miles. Started to get grinding sound when I applied brakes, which diminishes as I drive. Thought it was rust, but sound is very loud and sounds just like pads are gone and digging into rotors. The brake warning light is not on.
Dealer told me rear caliper was closing unevenly and recommended service---not covered by warranty of course. When I picked-up car same noise as before. The service manager told be that the car was just washed and the rust built up in the last hour---I could believe some built-up, but the sounds made my teeth ache. When we went for a test drive the noise got quiter, but was still apparent. The SM told me this is a "normal" noise. I have had many cars with disc brakes, dating back to a 1960 Jaguar; none have made this "normal" sound.

I've got an 03 Camry (211K mi.) with front and rear disk brakes. I have a pulsing/grinding sound from the rear brakes. I think the pulse is from the run-out of the disk/rotor. Took it to a Toyota dealership last year and they pulled apart, cleaned and lubricated the parking brake assemblies on both sides. Brakes ran quiet for about 3 months and then the noise came back. When the climate is dry, it makes all kinds of noise. When it's humid (above 80%) or raining it's quiet. It still stops good and there is no pulling to one side or another, so I figure my calipers aren't leaking.
I bought the car used a little over 3 years ago and don't know when the last brake job was done. I was going to replace the front and rear disks and pads and inspect the calipers for cracked cups or seals. I was talking to an old school mechanic and he said something about opening the bleeder line(s) when I compressed the cups or I'd damage the ABS control. I looked at my manual and it said nothing about this. I'm not looking to replace the ABS controller because of a silly mistake on my part. Looking for info about cracking the bleeder when compressing a caliper??

I have a 2003 Impala, total mileage little of 122,000 miles, I bought the car back in Dec 2014. When I bought the car I got all the paper work on the work the dealership did on the car prior to me buying it. One of the things they did was put new brakes and rotors on the front. Since then I have replaced the backs. However after about 4-5 months I notices that from the front passenger side when I had to slam on the brakes or was braking from high speed I would hear a grinding sound coming from that area. I have taken it to two places and both have inspected both the wheels and rotor's and say they are fine, they commented that the pads were not the best but more then adequate for this car. Of course when they drove it around it didn't happen and it doesn't always happen. Both places said it could be the pads or rotors but without replacing them there is no real way to tell. How can they both be viewed as good and in good condition and I get this grinding sound from the one front wheel from time to time when I break.

I have fairly new brakes on my 97 Chevy Tahoe with 202,000+ miles. For the last several months when I come to a stop, sometimes the brakes make a grinding sound (or 'boy-yoi-yong' sound- it's hard to tell) and the brake pedal feels like it 'slips' although the brakes do always stop the car. The brake don't always do this but it happens at least once or twice a day. Sometimes the problems is very mild, other times it's very noticeable. have it checked by two mechanics and they can't get the brakes to misbehave so they can't find the problem. All they did was flush the brake fluid twice and tell me it MIGHT be the master cylinder or the ABS system. My husband got laid off from his job and I am disabled. We can't afford to start fixing everything the mechanics THINK might be wrong with the brakes.

Back in December i purchased a 2003 Impala LS. It has about 103,000 miles on it now. Overall the car runs and drives great. However on very rare occasions I have noticed if I have to slam on the brakes or really break hard I hear a grinding sound. Now I have only heard it maybe 3 times in the time since buying the car and never hear anything under normal braking. I had the brakes checked and was told they didn't see anything wrong, but what might cause this grinding sound I have heard a few times?

In February 2014 I purchased a 2011 Honda CRV. I often travel and am gone for about a week. Every time I come back the rear brake are rusted. They have a loud thumping and grinding sound. I immediately took the car back to Honda dealership (2 time) both times they 'shaved' the roaters. I then contacted Honda headquarters to report the issue. They told me to deal with the dealership and take it to a local mechanic for other opinions. Car Talk will be my second opinion. Honda dealership told me that this is just the way it is. This is my third Honda, I have NOT had this problem before.

I noticed yesterday a sound, like a grinding sound, *sometimes* as I apply the brakes to stop. I'm at 68k. The noise only happens when the brakes are applied so I suspect there is an issue with my brakes again.
Some BACKGROUND info: At around 60k (or 8 months ago roughly), the front pads were replaced after the brakes were squealing and a pulsating brake pedal when stopping. The pads were replaced by a dealer. In addition, both front/rear rotors were turned at the same time. Rear pads had 40% at the time and were not replaced.
Some weeks later the pulsation came back and I went back again and they machined them again. For this current issue I was thinking about taking the car to someplace local (not a dealer) and getting a free brake evaluation of what is going on.
I'm also concerned that all this machining the dealer did to eliminate the pulsation may have decreased the life of the rotors and perhaps they need replacement now.

I thought I'd be free of problems having bought a new Toyota Rav4 in Jan. In June, with less than 3K miles, my husband had a (BIG) fender bender (turns out his meds made him blank out, he was driving at 10-15 mph) (and he is going on 80). Repairs cost over 3K, but I was able to drive it to the dealer. Soon after I got it back a month later, I started hearing a brief grinding noise under the accelerator, at speeds of 20-30 mph. Mostly after I took my foot off the accelerator, once or twice after I took my foot off the brake. This noise sounds like brakes grinding, appears very sporadically and briefly. I took it to the dealer and of course they could find nothing wrong, said everything checks out. They said to bring it back when it's doing the noise. Which it does maybe once a week, for a second or two. sheesh.What to do? I actually want to start all over, I do not want to drive with my ear to the gas pedal. (My husband now only drives in town!)

The brakes on my 2007 Hyundai Elantra make a grinding sound (almost like finger nails on wood) when I have tried to stop in icy conditions. It's also hard to get the car to stop and I end up pumping the brake. A Hyundai dealer replaced the front brakes over a year ago and Adirondack tire replaced back brake pads in the summer. Is the noise part of the anti-lock feature or does it sound like a problem?

We discovered that our 99 mercury Mountaineer had bad rotors. last night I hooked up a trailer and was going to work with a friend move a couch when I heard a loud grinding sound. I turned around and determined it was coming from the wheel. I purchased a new set of pads and started to change the pads. In the process I found a broken sway bar connector. I changed this as well. It still felt bad and there was a sound when I braked.
I took it to pep boys for a free brake inspection. They pointed out that the rotors needed to be replaced. I did not let them do it because I can not afford that right now. The car is a secondary not a daily driver. My wife says we shouldn't drive it at all. I say we can still drive it and expect I will have to replace the brake pads sooner than normal and replace the rotors when we can, later. My wife insists we will do more damage if we drive it as it is. I say what's the difference we need to replace the rotors anyway.

I have a 2004 F150 4x4 Fx4 supercrew with 5.4 engine and 46,000 miles. For the past three weeks now I have a periodic Grinding /scraping sound that seems to be coming from the front passenger's side of the truck. It can come on with light driving and braking in town or start while driving 70 mph down the interstate without even touching my brakes. The thing is I just about always have to come to a complete stop to make it go away. 10 Minutes later it comes again. It's loud enough for everyone around me to start staring at my truck. Sounds like metal scraping concrete and gets deeper as I slow down and when I fully press my brake pedal it goes "curchunk and the sound is gone for a while. I thought maybe my caliper was sticking or maybe the truck is trying to go into 4x4. One friend even suggested me to check the dust cover behind the brake for rocks.

So, last week I got my transmission replaced and they also had to replace the CV axle because it was damaged beyond repair when the Transmission self-distructed. They drove it after all the repairs and said it was driving fine, just that it had a belt squeak.
On my way home (30 min drive) about 10 minutes in, still in the city, my brakes start making a grinding noise and sort of a thump thump thump when I brake which sounds like its coming from the passenger side front, it makes me really nervous. It doesn't sound like any brake grindy noise Ive ever heard before and it wasn't making any brake noises before it broke down. (On a side note: it also made a weird noise maybe the first 3 times I drove it after getting it back and I turned the wheel hard to back out of a parking space, that used to be when I heard the belt squeak but I haven't made it squeak since I got the car back.)
Everyone I talked to said it sounded like it needed new pads so tonight I bought new brake pads and rotors for the front and got everything taken apart. The rotors didn't look bad at all, just some light surface scratches, nothing deep, no warping I could see, and the brake pads look almost brand new. I did notice that the inside brake pad on the passenger side was missing its little metal plate that is usually between the caliper and the pad, so I went ahead and replaced all of the brake pads hoping this lost metal plate was the issue.
I also turned the rotor by hand on each side while the brake pads were off and the only difference I could notice was when turning the passenger side one it made a little more noise almost like it was loose.
I got everything put back together and drove around the neighborhood with my boyfriend in the car to listen, the grinding noise was gone and it seemed to brake really well (never got above 30 mph.) However, on my way to return the rotors to advanced auto (45-50 mph) it started making the thump thump thump noise but without the grinding, still on the passenger side. I can feel it in the gas pedal and now it not only happens when I'm braking, but also any time I let my foot off the gas pedal. The only time I dont feel/hear it is when I'm accelerating.

i have with my Treg. Occasionally, like once every two weeks, when I am slowing down to almost a standstill, i suddenly hear a loudish grinding noise that seems like it was triggered electronically. I seem to think it happens when the auto box is shifting from 2nd to 1st before the car comes to a standstill, but not every time. Obviously when I took it to the dealer it did not happen!

So I just bought a 2004 Ford Focus. I did not drive above 15mph when I tested the car due to the lake effect snow that was occuring. Now that I own the car I have noticed if you try to stop going over 20mph the car starts to stop but last second it lurches forward a little bit. There is also a grinding noise that sounds like its coming from the back and a loud vibration that sounds like its coming from underneath the middle of the car. I'm trying to figure out if it is the brakes, tires or a leak in a brake line (those are all things my dad said it might be).

I hear a grinding noise from tire area when in motion and when stopping and happens only intermittently. I have taken my 06 chevy uplander to 2 auto repair shops and to a chevy dealership repair shop now and all three say they can't find anything wrong with it. shortly after, the noise happened again but now when it occurs the display screen reads... Service ABS system and service Traction system... when i turn the engine off and back on again the warning is no longer there unless the noise occurs then will read both again.

I installed a set of Brake Performance rotors ( slotted ) with premium ceramic pads and have had a bit of strange stuff going on from day one. When I first got them installed there would be a mild grinding or rough feeling when stopping. It got better over the first couple of day but was still there. I also notice a loud whirling or humming noise when I stop from high speeds. I called brake performance and they saids that it may be that the ceramic pad is to hard for the system. It sounded a little odd. The weather in AZ finally hit 77 yesterday so I have been driving with the windows down and have been noticing more of the grinding sound even when the brakes are not pressed.

TRUCK: 2003 F250 S/C Long bed 4x4 7.3 Diesel
PROBLEM: grinding noise in left front when slowing and stopping.
Starts as a howling noise, turns into a grinding as you brake and come to a stop. I feel it in the pedal and as it slows it feels like metal to metal brakes
WHAT HAVE WE DONE: Replaced both front hub assemblies (MOOG)... Replaced dust shields, rotors, calipers, pads as well as all new brake hardware.
At any speed when I brake hard it grinds and howls, I have taken out the 4x4 locking hub assembly and it does not change the situation. I am stumped!

The brakes in my new '05 Treg are really, really touchy, especially when going super slowly (1 mph or less), or stopping completely. I find it almost impossible to bring the entire vehicle to a complete stop without the vehicle "jerking" backwards - if you know what I mean. It's almost like the brakes were being operated by an on/off switch. I got the "nothing can be done, that's how they all are" speech today from my dealer. Any solutions? Different brake pads, maybe?

My vehicle is a 2005 Hyundai Accent GLS with 38,000 miles.
I recently had work done on my rear brakes after having a pretty horrific, loud metal-on-metal grinding/screeching sound. - the pads are still at 60 percent so they did not put on new pads, but they did a rear brake adjustment, shaved the rear rotors, etc.
That horrible sound is gone, but it has been replaced by a low-frequency groan from the rear brakes under hard stopping, from about 10mph down to 0mph. I honestly could not even hear it myself with the radio on but noticed it when coming to a stop without the radio on. It usually stops happening after a couple hard stops, then happens again the next time I get in the car and go somewhere.
To describe the sound, under those exact braking conditions it almost sounds like what driving a car through snow sounds like. Or a shoveling snow sound, minus the sound of the shovel itself hitting the ground. I am not noticing any corresponding vibration or decrease in stopping power.
Not sure if that makes any sense, but it's the best I can do. Could it simply be rust buildup working its way out? We have had a wet, cold, snowy winter and my car is parked outside every night overnight.
