Sonata NF (2006-10) :: Noise Like Grinding Sound When Brakes Applied To Stop
Feb 18, 2011
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.

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.

Is it just me or is this an ABS thing? during a snow storm i was going about 25mph and had applied the breaks and started making a grinding noise... if it is the abs how are you suppose to work with the response time for a quicker stop.

Coming to a left turn signal I was anticipating it turning red on me, and I drove into the turn lane briskly 30mph and then applied brakes as I made a u-turn. It sounded like a cross between dragging the front air dam and metal on metal brake grinding as I made the turn. Stopped immediately and did not scrap the air dam and all front end components checked out, okay. Car is driving just fine now, has only done this once.

Long story..couple months ago while coming home my 08 Sonata 2.4L manual 84,000 miles...started making this grinding noise and would stop when I pressed the clutch in and then sounded like something was grinding near the passenger front wheel.. well I get it home and the next morning my husband and I ride up the road so he can hear it.. was going to take it to the shop but it stopped and ran just fine till the other day.. crank the car and its fine.. once it gets warmed up and a few miles down the road it makes a knocking noise...but only when I let off the gas or idling .. even pressing on the gas just a tiny bit made it stop (even tried in while parked in the driveway with the hood up to make sure the engine wasn't just drowning it out) well I took it to the local dealership today and they said it was the flywheel and that it and the clutch and bearing needed to be replaced..

I heard a grinding noise from one of my rear wheels. After investigating, I saw that the OUTER pad was worn down all the way. I had only driven 15K and it had not been very long so I did not expect this. I also didn't hear the warning tabs as the they are on the inner pad and it had not worn down enough. I checked the caliper slide bolts and they were gliding freely. I checked under the boots and there was still grease in there.
My old pads had only been worn to 30%-50% so I installed those on for now. When I compressed the piston, I had a hard time getting it started and had to apply a bit of force with the C-clamp, but then it compressed without the need for much force. When I put the pads in, it was pretty hard to get them into the clips. the inner one required me to press pretty hard with my hand, the outer one was so tight, I had to use the c clamp to get it all the way up to the rotor.
I'm wondering what the cause may be. Are there some typical causes for why the outer pad may wear faster? I would think if the caliper bolts were stuck, that would do it, but they move freely? could it just be that the pad is too tight on the slider? How might I fix that? I tried filing them down a little but that obviously wasn't enough.
Also, now the pads on the right and left are uneven and the rotor on the right isnt smooth anymore. Should I go ahead and change out the pads and that rotor? Does uneven pads or a rough rotor affect the effectiveness of the brakes significantly? They are the rear brakes so I would think there is less of an impact. I know that uneven pads and a rough rotor will cause them to wear faster, but if I need to replace them anyways, I might as well wait til they wear down more.

1950 cadillac - standard drums on all 4 corners.
I put new wheel cylinders on each drum, and replaced the drivers front hose, as it was clogged. The passenger side I left because it works and doesnt leak. I've cleaned all the brake surfaces, shoes and drums, and bled everything.
When I brake, and only when I brake, the front right makes a grinding noise and the car pulls to the right.
I tried tightening the star wheel today to bring the shoes inward in hopes that would equalize brake pressure up front, but when trying again today, I got that grinding sound still.
There is no scoring or gouges on the shoes, drum, and the inner and outer ball bearings seem fine - round chrome balls with no discoloration, no gouges on the spindles. Granted I don't drive this far at all, especially now that I have this grinding.
How can I really tell if its the ball bearings? It only makes the grind when I am on the brakes.

I have a 2006 Subaru Forester with 115K miles. It's been well-maintained and well-loved.
For the past few months, the brakes have been inconsistently making a dragging/grinding noise when coming to a stop at low speeds (<5mph). It sounds to be coming from the front half of the car - I can feel it vibrating a little near the driver side. We've taken the car in to be looked at three times - each time, the mechanics think they've heard the noise and report there is absolutely nothing wrong with the brake pads or rotors. Twice they reported a shim was out of alignment. After the last shim adjustment, the noise got a little better - instead of grinding, it's more of a dragging sound now. Because the noise is inconsistent, I haven't been able to crack the formula of the conditions that produce it, other than that it only happens as I'm coming to a stop at very low speeds.
Is there something besides the brakes we should be having inspected? Does this sound safe to drive?

A couple of months ago the front driver side of my Sonata started creaking whenever I applied the break. I took it to a local mechanic as well as Hyundai service and after a couple of thousand dollars, it still makes the noise . Both upper and bottom control arms were changed, rotors, pads, brakes, bearings, strut mount, and some other minor stuff that I can't recall...its loud and ANNOYING....

I bought a brand new 2010 Sonata in April 2010. So far I only have 2500 miles on it. The problems I am having are:
1. When I apply the brakes, there is some vibrating sounds coming...
2. The passenger side front tire does not hold air more than 25-26 psi.. If I raise it to 34 or even 32 psi, it drops down to 26 psi within a week and then stops leaking...

I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.

Right this clicking noise is really annoying me now, every time AFTER i brake i hear this click, the faster i stop the louder the click is, also when I am in neutral and suddenly rev its clicks sometimes but rarely, I am thinking it could be a loose exhaust somewhere? Its definitely coming from under my foot area. When I brake cornering it clicks too. Checked my control arms and everything, that's not rattling at all? Need to get rid of this click sound!!

I have only 42k km or 26 k miles. Brake stops but soft. The brake pedal sink if you apply pressure after a stop. Feels like someone open a valve. The pedal go to very low. I am find the stopping power is poor. Brake fluid is brownish. I hope it is not the master cylinder.

So originally I was told it was my front brakes going bad, which was the case. To address the issue, I replaced the rotors and pads awhile back and the noise disappeared for a bit. Fast forward a month or so ago and I hear an on-and-off squeaking noise when the brakes are applied. It does not happen every time. Usually when I ease onto the brakes to a slow stop.
Figuring it could be my pads going bad for whatever reason, I decided to check my brake pads and rotors again. No odd signs of damage on the rotors and by the looks of it there was still plenty of pad left. I then sprayed some brake clean assuming it could be dust but there wasn't much.
I have not touched the drums yet but I'm thinking it could possibly be the drums or a bad bearing? The car is a 2012 with 38k miles which is the reason I'm doubtful of it being a bad wheel bearing. What could it be?

My car sounds like it's dragging something but when I look under it there's nothing there. The sound it makes is comparable to the sound a snow plow makes as its plowing the road. The sound is constant but gets worse when I brake. What could be the cause?

With only 1,800 miles on my 2016 Sonata Limited, the brakes make a high-pitched noise when applied and backing up. I noticed yesterday the noise has also started as I brake for red lights.

My right rear brake is making a grinding noise when the brakes are applied. I took the drum off a couple weeks ago and the shoes are just a bit worn. Just getting into the numbers printed on the side of the shoe material.
I could not see any thing that would be making the metal on metal sound. Are there any wear indicators on the OEM shoes?

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.

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?

I have a 2007 Sonata V6 I bought used two years ago. When I bought it mechanic serviced the rear brakes as the caliper was sticking. Now the rear brakes make a grinding noise when I brake and when I drive the rear brakes make a sound like slight metal on metal contact. I know Sonatas are known for brake problems. Should I replace the rear pads, rotors, calipers (including pins) and if so what brands are decent to buy? I have used rock auto in the past.
My car has about 198,000km on it (123,000 miles).
