Grinding sound just before complete stop

Hi guys. I have a 2004 1500 4x4. I recently replaced my front pads and rotors. After approximately 1 month, my wife commented she heard a grinding sound right before she came to a complete stop at the bottom of a hill. The rear rotors were grooved so I just assumed that it was coming from the rears and didnt think about it a again, until I drove it a week later and after making a few harder stops around town I heard the noise and it was definitely grinding coming from the front end. I looked around, but didnt see anything obvious. I took it to the shop and he took if for a ride. He said he thought something was going to fall off the truck. He pulled the pads and he thought there was a lot of metallic compound in the pads (an issue he has seen before) so they put a new set of pads. One week later it started it again. I let it go for another few weeks and then I replaced the pads and rotors both front and rear. No noise for 4 weeks and then it started again. It only occurs after the brakes get heated up. Not general braking, but more aggressive braking (quick changing light) or coming down a hill. The noise is not there while decelerating, but just at the last moment before you reach a complete stop. Any ideas? The pistons all pushed back into the calipers real easy, so I didn't think it was a caliper problem, but now I am second guessing that. Thanks in advance for the help.

Well it seems to be brake pad related if its going away for a month or so then out of no where returning are you running semi metallic pads or ceramic pads

I am using Duralast ceramic pads from Autozone. Prior to all of this I was using the same thing. When this initially started I had just put on Wearever rotors from Advanced, so I switched back to the Duralast rotors thinking that was the issue, but the noise returned.

I called the Technical Support line for Autozone to see if thy had any thoughts/suggestions and after my description, he nicely said it sounds like this set-up does not work for this truck. He suggested I put on a set of semi-metallic pads.

I never liked the ceramic pads. Bought a set and the one side disinergrated on a hard stop and destroyed a new rotor. This new truck nothing but factory brakes.

This is a pretty old thread, but I wanted to complete it. A few months ago, I finally replaced the front pads and rotors again. This time I used semi-metallic pads from Autozone as the guy from Technical Support suggested. I figured I might as well replace the left front caliper also as I didn't have much faith in switching back to the semi-metallics as the solution. After dealing with the leaking brake fluid around the banjo bolt, the brakes have been working great. I guess I will be sticking to the semi-metallics.

I tried ceramic on my truck and they made way too much noise. I will only use Semi-Metallics on mine.
