2000 A6 2.7T brake squeal

[kf21857 at comcast.net]

I bought a can of the 3M brake lube.  It looks like regular anti seize compound but thicker and copper colored.  It didn't help a bit.  If anything it is worse than ever.  Guess I will pick up a new set of pads from the friendly local Audi dealer and see if those work better.  I didn't have the problem with the old pads so it has to be something to do with the material the pads are made of.
