Jack, does this post relate to the one you put up re the front wheel bearing noises?? You may just have a warped rotor. Does the pedal pulse at all? You should try to eliminate simpler problems before rebuilding calipers. Is the noise from one side or both. A better description of the noise would be helpful..

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
