what size bolt's do you use to rotate your BOBBIN'S :tt2:
Hi I just use a 10mm Allen on a socket seems to do the trick think it depends on how tight they are ..spray some brake cleaner first or wd40 lightly ensure to clean disc afterwards
Kenny
personally I wouldn't put WD40 anywhere near a brake disc
On the GSX1400 the usual method used by owners was a screw extractor inseted and turned by hand or a low speed battery drill.
TBH it is not something I have yet felt the need to do with the GTR.
I'd also be dubious about using lubricant around the brakes, but a bit of brake cleaner might not hurt to ease things up perhaps?
The best way to sort the seizing bobbins is to fit Brembo discs and forget about it.
