Tried to remove the front callipers on my T32 at the weekend (big disc version), so that I can paint them (yes I know you can paint them without taking them off, but that would not satisfy my OCD), but it appears that I needed a fitting that was not in my toolbox. Can anyone confirm if it is a 9mm hex fitting that removes the calliper slider? I know it is a 21mm socket that then removes the calliper hanger, but I just could not get the slider off.
