Best way to deseize brake disc buttons?

The buttons on both the front discs on my ZX6 have seized up and the discs have no play in them.

So far i have soaked them in brake cleaner, gt85, tried to use the nut and bolt through the button method, soaked them in more brake cleaner and wire brushed them, but still no movement, ive put more gt85 on the buttons and i am going to leave it over night and give it another try tomorrow.

Any one else got any other tips?

Thanks

put a bolt through them and spin them up with a drill (slowly)

I've used grips on the edge of the buttons to turn them (on the inner face of the disc). It might mess up some paint on the carrier which is why I suggest you do it on the inside.

Managed to find a bigger nut and bolt and managed to turn them

Loads of crap came out but discs still don't move, I know they don't move much but they are solid, going to give it another bash again tomorrow
