Golf VI R :: Scraping, Metal On Metal Sound That Diminished A Fair Amount When Brakes Were Warm
May 23, 2012
I picked my R up three weeks ago tomorrow. I took it in this morning because there has been brake noise from day one. The noise was a scraping, metal on metal sound that diminished a fair amount when the brakes were warm. I only got a very brief conversation with the service agent at the dealership this afternoon, and all he told me is that they had to order in new brakes. I don't know if it's just pads, or calipers or rotors or the whole deal! I'll get the whole scoop tomorrow.

At 75K my passenger side rear brakes were making metal on metal sound. I was really surprised as I have always learned that the front brakes take 80% of load and they always go out before the backs. So I took the wheel off and sure enough the pads were metal on metal. Changed everything out. (new rotors). I then went over to the driver side rear brake. Looks brand new. The pistons were barely out. I figured this caliper is bad. (I haven't change yet)
When I drive I can hear a very faint metal on metal sound when I brake. VERY FAINT. So with 75K miles on I figure the front brakes are due. Today I took the wheels off and inspected them. Tons of pad left on both of them. If I didn't know better I would say a brake job had been done very recently. (I've owned the car new so I know they have not had a brake job) However after reading many articles on this site I found a thread where one user said he was changing his front brakes for the first time with 110K on them and the pads still had 10K left in them. So the fact that my front pads are still pristine at 75K may not be a big deal (or not as big as I thought. Also I am not hard on brakes.)
However I'm not sure what is going on. Why would the passenger rear brake be metal on metal at 75K and the three other pads are like new. Is the passenger rear the only one working (or working much harder than the others) meaning the other three are bad? Or is the rear passenger bad and the other three are good? I have a working knowledge of cars but I am by no means a mechanic.

This morning on my way to work, pulling into the parking lot around 20mph. I hear a metal on metal grinding noise. (almost to the sound of a muffler dragging on the ground type noise). Then that disappears for a bit, hear a loud metal clunk then some high pitched sound. All within say 30 seconds. Definitely coming from the back, but can not tell from which side.
Things I've checked in the parking lot:
Nothing hanging low, exhaust seems in-tact
It doesn't look like the brake shields behind the rotors are bent or touching
Sounds still happening if on or off brakes , on or off throttle.
It seemed to happen only at lower speeds. Disappeared once I got up to 50mph
Just took it out for a drive, that loud metal clunk happened when I put it into reverse, drove around, no other sounds. I just don't have a warm fuzzy feeling that this will just disappear.

My wife drives a 2010 Honda Odyssey. Yesterday she told me that last week it started making occasional sounds like metal scraping. I heard it today and it sounds like a chain dragging, or something going on in the wheel. The sound lasts for less than a minute, and is then gone. The sound changes pitch/frequency with speed. It only happens with the car in motion, and only after it's been driving for awhile. It sounds like it's coming from one of the left side wheels.
There are only 36,000 miles on the car. We live in Northern California where the climate is mild and there's never salt on the road. I'm wondering if this model has problems with wheel bearings, or something else.

I hear a metal on metal scraping/screeching sound with the windows down and only when i drive by guard rails and other stuff sound reflects off of. I saw the traveling hub zerk thread and that's what made me think of it. I've zerked every fitting I've seen, but this ones new to me. Problem is I can't even tell witch wheel (if any) it's coming from. It's consistent with speed.

The brakes were sounding like metal on metal. Three wheels in, some of the pads needed replaced but none were worn out. I got to the right rear wheel and the inside pad is worn to the bracket but the outside pad hardly looks worn at all.
I'm already replacing rotors, pads and calipers (I wasn't going to replace the rear rotors or calipers until I got to this wheel). Is there anything else I need to check because of such uneven pad wear?

I have a 2007 hyundai sonata, this car is my daily driver. I put 180 miles on it a day around trip. Currently has 180,200 miles on it. Last Friday on my trip home when i turned right I heard a metal on metal sound. I slowed down went straight and it went away. Talked to a few people and I think it may be the wheel bearing. Even if I hit a road reflector it starts up. It's the front left wheel. Get on the breaks it goes away.
So my question is... Wheel bearing??? And can I replace the whole hub and fix the problem or do I have to try and press the bearing out?

I have a 2003 Toyota Solara 4 cyl. auto. transmission. I recently had the head replaced. Now it is making a metal on metal sound near the drivers side of the engine. It makes the sound during idle, when I change gears, and the sound increases when I rev the engine. What could it be?

I thought i heard this yesterday when i left work but i was tired and said its in my head, THEN i go to leave right now and sure enough its a real sound, you can hear it very well through the front grill and then if you turn the volume up you can hear a ticking sound ever half a second or so, it also speeds up when i was pulling on the throttle cable. And after the truck fully warms up it goes away.......

My 2011 2.4l Sonata made a metal on metal sound suddenly the other day. About 4 days ago, I drove about 2 hours away from where I live, Mostly highway, about 80mph to a go kart race. Got out of the car for a while and came back in and was pulling away to run the store and as i started to approach the first stop sign maybe 500-600 ft from where i was parked, i heard a bad metal on metal sound, came to a complete stop at the sign and it stopped. Went back to the race after driving to the store about 5 miles away.
Got in the car to leave and same thing, just to the stop sign 500-600ft away. Drove home like i said mostly highway, and didn't hear a thing. Today, about 4 days later, I drove to Chicago O'hare airport, about 30min away, and it was fine the whole way there. However on the way back, after about 20-25min, I heard it again. So I came to complete stop as I was forced to by a traffic light as I was taking my exit off the highway, and It started making that sound again. So i came to a complete stop at the light and started moving again when it turned green and couldn't heard a thing.

I have got this noise which sounds like a light skimming of metal on metal. It sounds like a roller (airport baggage) spinning. It can be heard mostly when driving next to a wall or past parked cars. I suspect it being the bearing in either the water pump, idler pulley or even alternator. The car has 330000 kms but it is serviced regularly in which all fluids have been changed over time. I just want to drive through a tunnel and not hear any non harmonic sounds coming from the front.

I have a 2011 Santa Fe AWD Limited. 90,000 miles. I have a strange sound I need identifying. At first I thought the sound was my AC depressurizing, but it's not that. It sounds similar, but has a faint metal-on-metal jingle sound to it, like something is rubbing or something is rotating and intermittently hitting something just slightly. The mechanic went in to change the water pump because it was leaking, and he thought that the water pump when rotating was rubbing because the rubber ring/gasket was failing, therefore making that sound. Not it. Tired rotated and new brake pads put on. Still there. To be clear, the mechanic never said he heard the sound. I just told him about it.
I can hear the sound when I turn the car on and put it in reverse start backing up. I can hear it when I let off the brake (driving and in park), which lead me to believe that it could have been the pressure in the Master Cylinder or ABS. I don't know now because it does it intermittently when I am driving down the road with no brake applied. When I park, I put the car in Park, get off the brake and just listen. And I can hear it. When it is in park it is more rhythmic, with two or three second breaks in between. kshhh kshhh kshhh kshhh. (I hope you like my poor attempts at sound effects.)
Is it the ABS system? Don't tell me it's transmission related. I just bought this car (used at 87,000 miles) and already had the struts done, the water pump and drive belt done. For what it's worth, this car's passenger and back seats vibrate at 60+. Not sure if that has anything to do with this sound, but thought I would mention it. New struts and tire rotation did nothing.

I own a 2010 Toyota Prius that recently developed a metal-on-metal whining scraping sound when moving. It does not make sound when the vehicle is stationary, and it's intermittent - which makes me discount the rock-in-disc-rotor idea (not eliminate it, mind you). It's quite loud when it occurs, able to hear it over the stereo. Luckily I was near work at the time, so I went there - but the shop can't even look at it until Monday evening - so I am a bit panicked.

I have a loose, binding, metal on metal sound on my steering wheel shaft. I have removed the steering wheel, replaced the clockspring, because when I removed wheel clockspring was in pieces and I thought that might be the issue. Guess not, because I'm still having problem. Other than having to remove or replace the whole steering column...

I notice that when I close my door, it actually sounds like metal on metal. Looking closely it doesn't appear to line up well with the latch on the door.

I've been hearing a metal on metal sound coming from the brakes. I checked the pads with the wheel on and they all looked good. The back were replaced before I bought the car back in October. Last night the brake warning light came on, so I brought to my local shop. Longer story short, the inner pad was completely worn out, but the outer's were good.

For the past few months, pretty consistently, whenever I engage the clutch from full stop into first gear (it does it when starting in second gear too; and reverse) there is a pretty obnoxious and loud screeching noise that I would liken to a subway/train braking or just metal on metal grinding situation. When I took the car in to Douglas for an oil change and APR Stg 1 flash, they told me it's just the brakes being cold, etc. After driving the car some more, I really doubt that it's the brakes and I can reproduce this regularly by slowly releasing the clutch and get the noise usually just before the gear engages.
That car has just over 16K on the clock and has never been abused. The clutch pedal feels fine and there is no issue shifting into any of the gears other than the noise. No mods other than the APR Stage 1.

I ease off the brake and i hear this rattle coming from my car, like metal on metal. But really high pitched like something got loose or something. Tick tick tick tick.

I have a '06 F150 King Ranch with a after market lift. I sometimes hear a cracking, metal stress sounding noise from under the right side under carriage, I thought is was my brakes or shocks or something. If I take a right turn down an angle while braking or it happened during a rainy day going straight at a slight downward incline during braking, there's a knocking like pac..pac..pac..pac sound from under my rear or sometimes front passenger side fender well. I've taken it to a brake specialist and had it inspected by a mechanic, but no visible signs of a problem. What this might be? I told my brake specialist to check my anti lock system as the sound is evenly spaced and he said nothing is wrong.

This is finally getting too annoying to ignore. The noise sounds like i'm dragging a piece of metal along the ground whenever i turn right. the sharper the turn, the louder the sound.

I have a 2000 Toyota Solara with 145,000 miles. When I make a right turn, there is a scraping sound like metal against metal. Its not loud or shrieking. Its hard to hear over talk radio. But in the garage I can hear it, and its been getting louder. I haven't changed or replaced the tires in awhile or had any other work done to the right tire since long before the noise started. Is this something serious that requires immediate attention or is it some loose piece of plastic?
