If your RST still has the correct master cylinder, it will be 25mm, but they are obsolete now and if it's been replaced, it might have been with the 23mm non-RST one.
It probably is the pads. 325mm discs are too big for the RST really and for road use I think you can over-pad them. Try some very tame pads and see what they feel like, not that Green Stuff is that fierce!!
Did you bleed them properly?
