Hello, I've been tring to change the rear brake pads on my 2001 S6 Avant. It was all going well until I tried to push back the caliper. I used a G clamp which did not work, then I went to Halfords and bought a winding tool which I could also not get to work. I'm worried that because I used the G clamp first I have damaged the piston. Any advice would be greatly recieved such as what direction should the piston be turned, I believe its clockwise. Its also hard to put alot of force behind the rachet when turning the tool as I do not want to damage the brake hose. I have tried it with the caliper off and also with 1 bolt in. A simple job that I'm trying to save money on has turned into a bit of a pain. I have reassembled the car and it all seems fine on the old pads. If anybody has any tips that will be great, maybe the piston can be very stiff? Thanks in advance for any help. Cris
