Hi Guys, I've just swapped the rear disks on my 2000 S4 avant. No problems getting the disk done but I really struggled to wind the pistons back in. I'm wondering if I'm missing something, or if the return is something that can go wrong. I managed the off side but it was really tight. After a short time with it moving we got the new pads in. The problem was the near side that was alot easier to move but didn't retract. In the end we put the old pads back, we didn't get the room to get the new ones in. I thought I'd post on here and see if some of you knowledgeable folk could tell me what my mate and I are missing, apart from mechanical talent obviously. Thanks.
