Ok first let me say I'm not a newbie...I have good common sense when it comes to cars.
My issue is that when I'm driving, I can let my foot off the gas and brake and let it roll and I can hear a squeeking noise going to the movement of my wheels. To me, it sounded like it was coming from the rear.
I took my car to a friend/mechanic and he said that it was my brake pads, they were low. Now what doesn't make any sense to me is that if my pads we're low, wouldn't they make a squeeking noise when I apply brake? I mean, when you don't apply the brakes, they just sit there...so how would it go to the movement of my wheel? I can fully understand if it made the noise while I was applying the brake, but I'm not.
Also, another thing is that I'm braking pretty much the same as when I first bought these, not much less in braking. If you didn't know, I have the Powerslot Rotors (cross drilled) and Performance brake pads. I had them installed earlier this year.
Anyone have any suggestions? Is he right or am I correct?
I really need to know cause in 1 week I'm leaving for Indianapolis so I want to know if I should be careful or not. Thanks for your help.

He is right. The metal backing on your brakes is metal. When they pad gets low the metal starts to rub on the rotor. You can most likely see a ring around your rotor where your pads go. That is the metal of the pad cutting into the rotor.
The pad gets lower and the distance that you have from rotor to pad decreses each time.
That is why when you change brake pads you have to compress the cylinder or else you can't get the pads around the rotor. Hence the reason as to why you have a squeek.
Same as me. LOL

Yes you are so shut up.
Check your bushing things where the rear suspension pivots on the frame. Mine where "gone" and I had that same sound. Drove on that sound for about 6 months no problems, then I replaced them with some junkyard ones and packed that area pull of grease. No sounds seince.
ok...now my question is wouldn't it be away from the rotor when not applied? How would it squeek if it's not touching it. Also, when I apply braking, it doesn't make any noise...the noise actually stops.

Because the pad is so low that the metal has cut into the rotor. Thus allowing for area for the metal to travel. The rotor will wear out before the metal on the pad. There is about less than a millimeter of space between a pad and a rotor. The rotor is not perfectly flat ever but it is damn close. That is why it sqweeks instead of a constant noise.
It sounds off faster the faster you go right?
I'm just not thinking it's the brakes. The problem I had was I had a sweaking noise when I decellerated or made any kind of abrubt manuaver. My bushings (I guess thats what they are) were torn up and gone. The metal on my rear suspension was grinding in the pivot point. When you turn or slow down they are kinda sitting there with very little force in the pivot, the suspension is holding the pressure. When you brake, you car dives forward and the pressure is moved from the coils to the pivot if your bushing there is blown.

Ok. I guess I understand what your saying. Now my question is...do you think I can make the trip to Indy without changing them. I would do it now but low on cash and also I'd have to have them shipped out to me which would take a while to do so. I mean I figure this, on the highway, your not giving it much pressure or really giving any type of braking force. What you guys think? It sounds risky but can I pull it off?

I drove on mine for 6 months to get to work and back and used it at the track. The squeeking is just embarrassing. I'd think you'd be fine. Go get some packing grease and smear that stuff all up in there and it will go away for about 1 week or two as long as water doesn't get up there in it.
Not one to say you will be fine but I guess if you take it easy then there will be no harm in it except that you will need new rotors by the time you get back. They will not be able to be cut down after that. I am gonna replace mine anyways so I don't care how long I go with that noise. I just need to do it within this month.
What is the possibility of something being inside the pads (example: pebble) causing that noise? Also, if the pads were low, wouldn't I experience extreme difference in braking performance?

Slim to none. Yes you will start to experiance less brake performance but this just started right? So the differance in braking performance is not gonna be really noticable just yet.
The steps of disk brake pad death:
There is a little clip that makes the squeek sound, it's attached to the outer pad.
When brakes wear down they first squeek only when braking. This means your getting close, but they're still gonna work the next time you hit the brake pedal. When the caliper is compressed it pushed that clip into the rotor, makeing the squeek.
Drive like that for a while, then they'll start to squeek all the time, except when you are braking. The clip is now close enough to squeek all the time (not enough pad to push it back away). When the brake is applied the clip is squashed, and can't squeek.
After a bit longer, it won't squeek at all. If you're dumb you think some problem magically went away on it's own. If you're smart you know that "magically went away" = "something bad about to happen".
Next you head the grinding. You will also notice it's harder to brake. Not a huge difference, but definately noticable. This is bad.
If you further ignore the grinding it will grind through the rotors. The grind will turn to a clacking-grind as it eats the interal ribs. This is horrible. The car might stop if you try to use the brakes, if you went to church last Sunday.
Eventually you'll get to the point where the caliper is fully extened. It will no longer push against whatever is left, if anything. You will not stop, the brakes will not work at all.
If you're sure it's coming from the back then I think A.15 is right. If you're not sure, it may be your brake pads getting low. If they're still squeeking then you're ok. When they stop you know you waited too long.
CTS, I think your completely right.
At first it sounded like it was coming from the rear but it is coming from the front.
It actually just started a few days ago. I'm trying not to drive my car hard or at all until I have to go to the bash.
My question is, do you guys think that I will last the long trip to Indy...I figure being on the highway, I'm not using the brakes much so they won't wear much. Fortunately I work right up the street so I'm litterally going to stay at home till I go to work or go to places I have to go to.
How long you think it will go for before it stops making the noise?

Go to autozone/oreiley's/pep boys... get some new pads, and put them on (and get your rotors/drums turned if you need to).... brakes aren't something you want to ignore.
Front disc brake pads are easy to change... at most 30 minutes for both
Rear drums take some practice... only do one side at a time (so you can look at the other side to see how it goes back together)... 2 hours tops for the rears
In my experience brakes will easily last a month of squeaking under normal driving conditions. My started to squeak a month ago, I ignored it until I got to the second step (all the time squeaking). It's annoying, but not a problem.
They will stop squeaking ("magically goes away") before you are out of pad.
I would guess that you'll be good to go to the bash. Like you said, you're not doing much braking on the freeway. And they still work perfectly fine while they're squeaking.
Mitch is also right. I can do front brakes in 40 minutes (I'm lazy). Your rear brakes will take longer, especially if no one has taken the drum off for several years (rusts on pretty bad). But I've got a 97 with 87Kmi and I have 1/3 left on my stock shoes (pads are for disk, shoes are for drums). They last forever cause they do next to nothing (note: this is by design).
See the maintenance section for directions if you don't know already. You will need a jack, 3/4" socket, 3/8 Allen socket, and a big screw driver or pry-bar.
that squeaking is just the brake wear indicator on the pad as C.T.S said above. It's just a little piece of metal that sticks out along side the pad that rubs the rotor once the pad gets so low---thus, the squeaking sound.
bottom line---get new brakes.
Well I would change them but you guys have to understand...I have cross drilled rotors. I cant put regular pads on. Also, I'd have to order special pads and rotors and that costs more and it wouldn't get here before I have to leave for the bash.

Standard pads work just fine, they just won't last very long (1/2 the time). Pads and rotors can be mixed and matched any way you want, and will work. Mixing (like we suggested) is a quick fix, and will not last as long. Same with performance pads with stock rotors, you'll create excessive rotor wear.
Nothing dangerous at all, just more expensive in the long term. You can pick up a quick set of pads from napa for $18 if you want it stop squeaking until you order performance pads. If you don't want to spend the $18, live with the squeaking. You should be fine.
How long did the last set of pads last?
Do you have urethane bushing anywhere? Stock bushing are rubber. Urethane bushings would be after-market (usually a flashy color). They will squeak bad if they aren't covered in Teflon-tape or white grease.
I might just do that as a quick fix....I might not. We'll see if I can get someone to help me with it in time before I leave.
No I don't have urethane bushings.

i also have a sweaking noise comming from rear but only when i hit a huge bump ...
