Yes
Larger rear cylinders will give more braking effect

Smaller reduces... so if your having lock up issues you reduce... not enough you increase

the biger the bore dia the more fluid it takes to push them out and more peddle trave will be evedent.
you should have a better brakes with the correct size for which ever brakes you are running.

So was there a difference in bore size between the drum front and disc front models? If so, what size was what?

Rear drums with disc fronts had 9/16 wheel cylinders and drums all round had 13/16 or 7/8s from memory
