Default unbearable break squeal!

The brakes on my Riviera squeal so bad it'* ear peircing. At everystop I find that people always look over and stare at the car because of how loud the squeal is. I've tried new pads and they made absolutely no difference. It sounds like metal-on-metal contact and it'* gotten to the point that you can hear it inside the car at 55 MPH+ with the radio cranked! (and you'er stopping of course )
it'* hard to hear because of the wind and the recording is bad, but you can hear the squeal on this sound clip. (limited download because of bandwidth limitations.)

please! anybody have any ideas on how to get rid of this? it'* horrible!
btw, this clip was recorded when I was only going 2MPH in my driveway.

So you changed the pads? How are the rotors? Maybe its a bad caliper?

What kinda pads? Ceramic on stock rotors?

I have Raybestos "quiet stop" pads on it. Not so quiet, eh? lol. They're not ceramic but, rather, "organic?" The rotors I'm not sure what they are, but they seem to be in excellent condition. No signs of warpage by looking at it or feel. (no vibration at all when stopping.) I don't know enough about how breaks work to have any real idea of what would cause the squeal. It soudns a lot like the 'worn break pad' warning that you get when your pads are shot, but the pads are new. (replaced them myself)

SOme more info: They only squeal when going forward. If you slam on the brakes the squealing goes away for a while, but comes back very quicly. The squealing only happens during light/moderate breaking (IE. normal braking levels.) They are totally quiet if you are doing hard braking (sound like normal brakes).
If you stop using only the rear brakes (by using the emergency brake) they do not squeal, so it'* definately the front brakes (the only ones I've replaced.)

Are you sure the wear indicator on the pads isn't out of adjustment? That little metal feeler on the front of the pads.

it is very possible that it is.. only problem is that I have no idea how to adjust it and how much.

I have always considered the combination of ceramic or organic with stock rotors a bad combination.

Jason may be onto something...but it sounds to me like a replacement part not a repairable part.

Yeah tell me about it

You can do something about this. Which side does the noise come from? If you think both are bad, then take one wheel off, pull the pads, bend out the feelers slightly, and try that. Maybe some brake cleaner
