2000 A6 2.7T brake squeal

[Mark R]

Yes.  Use a synthetic, high temp lubricant everywhere two pieces come in
contact with each other (pad backing, pad ears, caliper pins, retaining
hardware, etc.).  The front carriers of the A6 2.7T do not have slider pins,
but the rears do.

I use the lubricant on track driven cars (including my own), but not pure
race cars between insulating titanium backing plates and the pads
themselves.  But it can be used between the insulating plates and the
calipers, as the temps there are typically under 550-600 degrees F.

My experience with the tacky/sticky products is poor.
