We all know that some '05+ S3s have problems with their front brake pistons sticking to their seals and increasing lever travel. My 11/05 production '06 has coated pistons and the brakes are excellent and the lever travel is short and stable. My brother's '05 S3 has uncoated pistons and his lever travel is long and increases after a piston push.
On that basis, I (like many of us) believe the solution is to do something to keep (uncoated) pistons from sticking to their seals. I happened to see the following product at the local Kragen last night:

The Product Data Sheet at the Permatex web site says,
"Permatex Ultra Disc Brake Caliper Lube is a green, environmentally friendly, non-melting, pure synthetic lubricant. It is formulated to lubricate under the most adverse brake conditions, assuring that critical caliper pins, sleeves, bushings and pistons remain lubricated throughout pad life."
This sounds like it will likely solve the brake problems for those with uncoated pistons. Has anyone tried this product? For less than $6, it seems very worth trying.
