changed brakes, still squeaking noise
I just changed my front brakes to the Duralast Gold because they were starting to squeak, and after changing them the noise is still there. It isn't nearly as bad, but I was wondering what might be causing this? It is a 2007 TL-S. The rotors seemed somewhat worn when I changed them, but would that cause the noise or is it possibly the rear brakes?
Also, if it is the rear brakes, can I get the same Duralast pads I used for the front on the back..or do they make brakes specifically for the rear?
Thanks!

Most likely you did not bed them in and this is why they're squealing.
If you did not have your rotors turned, you should bed your new pads in. Bedding in accomplishes three things. 1) I forces the pads to "gas out". 2) It forces the pads to marry or mate to the surface contours of your rotors. 3) It imparts a layer of pad material on the rotors.
Here's what you do when bedding in.
o Find a section of "lonely" highway where the speed limit is at least 55 MPH and use it early in the morning where you are less likely to encounter traffic.
o Make 8-10 hard brakings from 60 to 10 MPH (do NOT stop), accelerating back up to speed quickly for each successive braking. For your first attempt at this, do 8 brakings.
o At around the 5th or 6th braking, you will probably encounter fade. Ignore it and continue with the process.
o When you've completed the braking process, continue to drive the car normally for another 15 minutes, avoiding any use of the brakes at all during this last phase.
If the squealing has not stopped, you may have to do this again. You can see the importance of finding a piece of highway where it is safe to do this. I did this at 6:00am on a Saturday spring morning on a section of four-lane highway 15 miles from my house which was about 20 miles long.
Or you could just live with the squealing and see if it goes away. Here's a link you might find interesting.

Could be the shims were not fully/properly greased.
Front and Back brakes/pads are totally different on the TL-S. You might still find a Duralast pad, but it will be a different part number.

I have the exact problem :(

I have the 07 tl s also, and i have the same problem as yours, it all started when it reached 16 k , first i thought it was the front pads had worn out, so i took it to the mechanic to have the pads replaced , and since there were little grooves on the rotors i had the rotors cut as well. yet that didn't solve the problem. so at 24k , i decided to take it to the acura dealership , and guess what , they said that because i had the pads replaced at some place else with the after market brake pads , they wouldn't fix it for free, they wanted $ 700. even though i have gotten 2 cars from them in the past 5 years. i got the hell out of there......
