I have an intermittent high pitched squeeling noise coming from the front left wheel-area. It only comes every now and again and it sounds like a high pitched metal to metal. It stops when i hit the brakes and it alternates when i turn the wheel. Dealer said they couldn't find anything wrong with it. It tends to happen in warmer weather. It might do it 4-5 times in one day and not do it for a month. It also only occurs at low speeds, usually when I'm trying to find a parking spot or turning at a red light

Is there anything to grease? Or is it my brake pad? Or is it something entirely different?

 

I am having this exact problem and cant seem to figure out where/what this is. Mine also happens while I am trying to turn into parking spots and stop signs. I'm thinking that its nothing major but every time it happens I wonder what the hell it is!

 

It is extremely annoying. I have no idea. It happened before I put my AS 2.5 on so i know thats not it. Maybe its the breaks??? But wouldn't it happen frequently if it was? I'm baffled

 

I feel the same way.

I've posted this problem on another site and they lead to believe it was brake related... i'm not soo sure that it is tho b/c like you said it only happens every once and a while.

 

On my old 99' F-150 the front brake pads had wear indicators on them. It was basically a small metal bracket the was riveted to the brake pad. When your pads wore down, the metal bracket would drag on the brake rotor producing a high pitched squeal when lightly pressing the brakes, and sometimes while turning. It's whole purpose was to alert you to have your breaks serviced soon because the pads were wore down.

 

When I lightly press the brakes, it goes away...I've thought about changing the break pads but i've only got 24K miles on the originals. I may just pull the pads off and take a look at them although I am completely ignorant on how a brake pad should look

 

X2....

 

hmm...

 

The metal tab would only squeak with light pressure, if you hit the brakes hard, the metal tab will have too much pressure on it in order to vibrate and cause the squeaking noise. If you pull your pads off, you should still have about a 7/16" or so of pad left (approx at 24k miles). There should be NO metal on any part of the pad touching the rotor, and if your pads do have a "wear indicator" on them, take a close look at it and the corresponding part of the rotor where it would touch, see if there is any mark of wear. Also, take note of how much brake dust has accumulated on and/or around the pads, if there is black caked on brake dust, this can also create the squealing noise. And last but not least, take note on if shims have been installed between the brake pad and the caliper, there could be shims, or some stuff that will look like silicone, or nothing at all. It there is nothing at all, then that will also cause squealing. If that's the case and everything looked good and not wore out, then I would clean everything up and put some anti-squeal shims or compound (comes in a small bottle at you auto parts store, usually bright orange in color and I think the name of it is "Disk Brake Quite" and I think it's made by CRC) on them (it goes on the BACK of the brake pad between the pad and the caliper), put it all back together and you should be good.

 

Thanks for the info...If it was my brakes then it would do it everytime...or nearly every time right???

 

Are your trucks both 4x4? Is the noise really loud and sound almost like gears grinding? I had a solenoid go bad in my 4x4 that was trying to engage the 4x4 at one spot but not the other and it made a horrible noise.

 

No its not a grinding noise...I dont use the 4x4 all that often but it works just like it should.
The noise is more like a metal on metal. Like i said above...i dont think its the brake pad because it might do it today and not do it for another month and then 3 times in one day. and only 24 k miles on truck.

 

Just a thought, but with 24k miles on it...is it under warranty? If so, I would take it in complaining about the problem, and if they fix it...GREAT! And if they come back saying that it needs new pads and it will cost $$$, tell them that you won't pay for them to do the repairs and you want another opinion. Then on the way home, stop by the auto parts place and pick up some pads (WAY CHEAPER at the auto parts store) and put them on your self. Most auto parts places will turn your rotors for free if you buy pads from them...

 

I have found that brakes are funny like that... if the pads are just right at the edge of being worn enough for the wear indicator to touch the rotor, then factors like brake dust keeping the wear indicator from vibrating come into affect.

 

When I had my blend door replaced I had them look at it. All the stealership told me was that they could not reproduce the problem. I hate going up there and waiting for 3 or more hours. I rather just pay the money for new brakes to see if thats the problem.
