Sonata NF (2006-10) :: Grinding Noise From One Of Rear Wheels - Brakes Worn
Jun 1, 2011
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.

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 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).

I took my 2010 Sonata GLS (86K miles) into the shop last Thursday for an alignment and new front brakes since the old ones were on the wear indicators and doing some squealing/squeaking on soft left turns. Got a call from the mechanic who said the rotors were also shot, so I had them replaced as well.
On my normal commute on Monday and Tuesday this week (approx 10 miles, 95% highway), I noticed that when the car was moving at 15mph or less in a straight line both front wheels were making a noticeable high-pitched squeal/squeak, which went away with increased speed and when braking. I figured it might be a break-in issue but when it hadn't improved by yesterday I made an appointment to have the car checked out by the mechanic again today.
Got the car back today and the same sound is still happening, though now it's in the 60mph range and seems to come and go regardless of wheel direction. The mechanic said he took the brakes apart, found no issues but cleaned and lubed everything as a precaution.
I'm starting to wonder if its the bearings that are shot, but the sound hasn't remained constant as I would expect with a bearing issue. All the parts used are under warranty, so the next step I have available here is to have the brakes and rotors replaced.

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.

Recently my 2001 Solara started emitting a scraping noise from one of the rear wheels. Mechanic says its a frozen caliper, and suggested a complete brake job (rotar, pads, etc). My question is, I've got reasonable skills, by buddy has major skills when it comes to working on cars, is that something that a shade-tree mechanic can safely do ? Also, as its a frozen caliper, does that imply I need to replace the caliper, or could it have frozen due to the pads ?

My rear brakes are grinding so I am preparing to replace all pads and rotors. Any special tools or procedures from when they did theirs? Do the rotors have retention screws? Do you have to use a special tool to push in the pistons?

My read brakes have been grinding. I bought new pads to replace them. After pulling the drums I noticed that they were hardly worn. 50,000 miles on the car. They was a bunch of brakes dust in them. Cleaned the dust out and put the drums back on. It was quiet for about 3 weeks, now the grinding is back.

My car came back from the shop yesterday with new brakes and pads and seems to be making some odd noises, both at low speeds and while breaking. I called the shop this morning and they said that this sound was normal for awhile but to come back in a week if it persists. Is this sound advice, or should I be driving my car right back to the shop?

I have 23, 400 miles on my Kia Sportage 2009 and just found out I need to replace both of my rear brakes.They were making grinding noise. Is this a defect? Seems like low mileage to have to replace them?Also my front brakes are down to 50%. Is this a known KIA issue?

I have a grinding noise coming from what I believe are the front brakes. It happens when I apply the brakes and sounds like the brake pad is worn out and there's metal-on-metal contact but when I checked the pads, they are at 80-90% (rears have about the same amount left). I hear it the loudest just before coming to a full stop, from about 20 mph down to stop. I thought it was caused by rust on the brakes but after I wore off the rust, the sound is still there.

My 2006 Sonata has an on again/off again problem with the left rear brakes getting very hot... Took it to my mechanic and of course the problem never manifested itself there and all checked out fine... Got to work last night and I could smell it as soon as I stepped out of the car and and the drum is glowing cherry red...

My son's Elantra is making a strange sound, which seems to be coming from somewhere in the rear, underneath the vehicle (in between the wheels). I can hear it with the car parked, idling. In gear or out of gear doesn't seem to matter. It's not very loud, but it's rhythmic. I checked the engine compartment, but I can't hear it at all up there. I *think* I can hear it while driving, but it's very hard to hear over the engine and road noise while driving.
The sound reminds me of a squeaky pulley, with a period of 1-2 seconds. The car has been serviced recently, and the mechanic said it was in great shape. Mileage is ~50K.

I have a problem with the steering. Sometimes a clicking noise is coming out from the front left side when I sharply turn the wheels or hit the brake. The car was in a local garage today and they couldn't find the problem. 2 mechanics checked the suspension, cv joint, axle, wheel bearing... also 1 of them driven the car and found nothing. Tomorrow I show them the clip below.

Just put on eibachs and car is randomly making a grinding noise when slowly accelerating or braking.. Also noticing a fairly loud clicking noise when going in reverse. The noise isn't consistent and seems to happen more right after startup. I haven't gotten the alignment done yet and was wondering if this could be the problem. Will try and post a video soon.

I just bought a 2006 Sonata LX V6 a few days ago and in almost every way it seems like a great car. My '08 GLS V6 which gave me 150k great miles got totaled in November, which really sucks, but I wanted to find another '06-'08 V6. I noticed when I started it for the test drive that the car made a bit of a grinding noise on start up. I didn't think much of it and figured that the warranty from the dealership would cover any problems.(I probably should've checked earlier, but the dealership's warranty only covers cam and lifter noise and engine failure) After I looked into the issue more, I found out that it is a fairly common problem on the early 3.3's with the timing chain tensioners. I'm pretty concerned based on just the nature of the repairs and the cost I've seen for them.
I'm the third owner so the 5 year/60k warranty is expired, but I know there is a TSB out for the issue. I can't find the TSB anywhere but I've heard to have it repaired the car has to make the noise on start, sit 10 minutes, and make the noise again. If it does, the oil needs to be changed and the test repeated again. Since I'm running Hyundai 5W-20 and an OEM filter already, I tried the test on my own. It made the noise on start, sat 10 minutes, and made it again. It is only for a couple seconds, but it's still concerning to me. I guess what I'm trying to ask is if what I've described is covered under the TSB. I really don't wanna have to worry about something like that right now, so my next question is whether the issue I have is detrimental to the motor. My worst fear would be to have the chain jump a cog on the cam gear and slam valves into pistons.

I just bought a 2007 Sonata V6 (GL or GLS). Before buying the car, the last owner had the rear brakes "serviced" because the mechanic said the brakes were "sticking" - charged the old owner $300 for it. When I am on the highway and I brake, the rear brakes shudder. Do you think the shudder is because the rear brakes are still sticking, or because it needs new rotors?

Need to determine the noise before I took the vehicle in to be serviced. I don't know if I would necessarily describe this as grinding...to me it doesn't sound like metal on metal..but it's not normal.
Only happens on a cold startup, and even then it hasn't been 100% of the time...probably 80% of the time though.

I found this thread, Grinding Sound On Statup but not sure it's the same issue. This just started. Vehicle has 150K miles on it.

Have a '06 V6 GLS w/ approx 105K miles. About a week ago I started hearing a noise. The noise sounds a lot like a brake pad wear indicator, metal grinding on metal. However, the noise does not seem to be related to use of the brakes. The noise only occurs when the car is moving. It is intermittent. Comes from the front of the car. Seems to usually occur when making a sweeping or gentle right turn. Speed does not seem to matter - can be going 20 to 60 mph. Noise will last from less than a second to as much as 5 to 10 seconds and then goes away.
I have taken a cursory look at the crankshaft damper pulley and it appears to be ok...

I have a 2009 Hyundai sonata, 2.4, 5 speed manual, gls, when I press down on clutch whether from a stop or when shifting, I get a loud grinding noise and the radio goes dead at same time!, I know it is the starter attempting to "engage", at least that's what I believe it to be, it also "'starts "from, the "on " position when I press on clutch.

A few days ago, my Sonata 2006 LX started making weird noises when driving at low speeds. The noise comes from the front driver's side area, they are not affected by steering or going over bumps. Usually get less intense when I accelerate or brake. At speeds around 5 mph, the noise is grinding and pretty loud. At higher speeds, it's more like banging and it's frequency increases with the speed. There was no effect other than the noise, but the last day at higher speeds, I can feel with the steering wheel a little vibration sometimes from the banging.
I've been having tough times renting a car during the weekend and I still drive on short distances, but I'm afraid it could be a safety issue or that I can be making things much worse to repair. The noises got worse since the beginning, but I don't think they are getting any worse anymore.
