I am trying to replace the rear brake pads for my g/f 2006 (late model) Jetta but have come into a problem. I have, or so I thought, all the tools I needed from working on my own 03 GTi. But once I got under the car I realized that the only bolts that look as if they are holding the caliper into place are Reverse socket bolts. I have up to a 12mm but that is still to small. Am I even right for thinking this is the caliper retaining bolts? I don't see anything else that holds caliper in place. The only other bolts are keeping the caliper halves together. If it is the reverse socket bolt then what size is it? Looks like a 14mm but no one I have called has one in stock. Suggestions?
