Many Audi's have rear brakes that require a special tool to "screw in" the brake piston. This is so that the parking brake will set. You will have to ask around as to where you can acquire this tool. Sometimes, you can get away with using a large adjustable channel lock wrench. Screw the piston in until it bottoms out. Then, replace the pads. (Axxis pads are very good). WHen you have done both sides, pump the brakes several times to reset the pistons. Voila!!
