Car is my '95 GT, all stock suspension. When the car is warmed up, after some driving (like freeway) I get a noise up front when the brake is applied or when I turn the wheel. It's not loud, but you can also feel it in the floor boards, just a bit. I took a quick look around the under side, but found nothing loose or worn. This only happens when warm, doesn't do it when the car is first started, or slow around town driving. Any clues? I'll prob just take it in during the week and have a front end place look it over, but would like to have some ideas before hand. TIA------------------

How many miles? Have you had the front brake pads replaced? Did you resurface the brakes when you did, if you did?Off the cuff, I'd guess your rotors are getting warped. Would you describe the noise as a chirp?

Not a chirp, more of a sound like something is contacting something. The car has 110K...brakes I haven't done yet, the pads have lots of meat left. But would that make the sound at stand still? After it's warm I can put the car in P and just barely move wheel a bit and get the car to make the noise. ------------------

Lots of things about this post leave me scratching my head. To get 110k out of a pair of pads and still have meat on them is rare to say the least. You typically don't get more than 30-60k out of a pair. Then you say that you hear this noise when at a complete stop? What, just pressing the brake pedal causes the noise, while in park? That would suggest maybe a caliper issue. The fact that you still have pads left at 110k, would agree that perhaps there's a caliper issue. Do you have meat left on both sides? Is the noise coming from one side, or both? Does the car pull when you stop (moving along, hit brakes, let go of steering wheel, does it want to change lanes?)

Sorry, should have been specific. I have only had the car a month or 2, so I'm sure the pads have been done since it was new. I meant I haven't had any need to do the brakes in the time I've had it. Anyways, the noise can occur at a very slow crawl, such as stop and go traffic, and the noise while turning wheel (same as the stopping sound) will occur at a complete stop, even with car in P. ------------------

Oh, ok!  I'm with you now. These posts are really hard to diagnose without actually hearing the noise. Fords are notorious for really loud power steering pumps. Any chance that's what you're hearing? You would typically hear that while your turning the wheel at low speeds, although you'll hear it at the turning limits also. Check your power steering fluid and make sure it's full. Might double-check your brake fluid also...hell, check all your fluids! Could also be bearings. When they go they can sound like a lot of things. Anywhere from mild clicking to grinding. Those can be somewhat dangerous to have go on you, so you'd want to have those checked soon. [This message has been edited by GTRocks (edited 05-24-2005).]

Yeah, I will be taking it in this Friday to a shop that I trust and have them check it out...the car needs a bit of an alignment anyway. I just wanted to know a bit of what could cause it before I take it in. Thanks for your help.------------------

disk brakes have a wear bar that will drive you crazy it is a little metal tap that contacts the rotor to say hello I am too low replace me,lol and it makes a screaching high pitch sound.
If you take the wheel off it is ussaully on the top in back of the rotor towards the front, 10 - 11:00 position.
just a thought.

Yup, I'm familiar with that little wear indicator, I remember it from my Dad's Bronco II. It's not a high pitched sound my car is making, just a creaky kinda sound. Hope they can track it down this weekend.------------------

The stock pads on the 94-98 Mustangs and GTs (not sure about the Cobra's as they are different front brakes) do not have wear indicators on them. None of the aftermarket pads for those calipers that I have ever seen had wear indicators on them either (not saying that I have seen them all). It sounds like you ruled that possibility out when you said it can occur with the car stopped. I, like the others, would have to hear the noise to be of more help. Just wanted to clarify on the pads.Scott

Well, took the car in this morning. They found nothing that would cause the noises. They did find the rotors are going to need replacing soon, as well as the control arm bushings having a little play, and alignment will require the cradle to be shifted to correct camber. But nothing that would actually cause the noises it makes, or at least that's what they said. ------------------

 I hate that. They look at you like you didn't really hear it. Sigh.... I assume that means you weren't able to demonstrate for them. Is it sporadic then, I assume? Or they just think it's normal?

It's sporadic, only had it happen 3 or 4 times. Guess I'll just wait and see if the small noise becomes a larger noise, then maybe it'll be easier to diagnose. Thanks.------------------

My 03 makes a thump every once in awhile up front. My wife freaks out, but it sounds to me like a duct door closing or opening with the A/C on. It too is something that happens both at a standstill and moving slow. I think at faster speeds we just don't notice it. I'm curious as to what you find on yours.

Sig, wish I knew what it was, but since I took the car in the car has not done it anymore. They didn't do anything, just what was needed to tell me what the car needed to have done. Still a bit of a puzzling mystery.------------------

Well, the car finally started to make the noise again, conditions when it started: stop and go traffic in warm (85 deg) weather. When I got home my dad turned the wheel side to side while I poked around under the car, heres what I found. It happens when the wheel is turned to the right, the noise seems to come from the area of the rack around the shaft that goes to the wheel, there is a sound similar to a spring being stretch (if that makes sense), all this coming from passenger side of rack. Inside the car it sounds like a groaning sound. Might take it back in, at least I've isolated it to the rack (i think). ------------------
