I have a 2004 Titan 107,000 miles on it. Recently it started making a thunk kind of noise when I hit the brakes. It only does it onces the brakes have warmed up and when I apply brakes going forward. The sound seems to be coming from the front left of the truck. I took a look at the rotor and pads and they're both wearing beautifuly. I double checked all the mounting hardware and its all tight. Any help would be great, thanks.

Do you have the tracks in the bed with the plastic cover on them? Try removing those and see if you still have the noise. They tend to slide back and forth making the noise you described.
