2004 R1200GS, front discs no longer floating due to corrosion of aluminium wheel expanding to fill the gap. Anybody fixed this without buying new discs and fixing bolts? I might try a large socket in my battery drill, switch it to hammer drill and put it over the fixing bolt so it rests on the disc fixing and buzz away for a minute to see what it does to the corrosion behind the disc BUT would like some feedback before I do it in case I have missed something
