A larger master cylinder bore will
increase pedal pressure. Pedal pressure to move my RAM pressure plate and single disc clutch has always been leg strengthening. Two months ago I replaced my .75" Girling clutch master cylinder, with a .625" Girling. The pedal effort is now substantially easier.
A Google search on the subject of master cylinder sizes will substantiate my statement. Here is one of them.
