Is there a better master cylinder than the stock one out there?

 

Better how?

 

Larger pistons/volume.

 

All that does is increase braking effort. How is that better?

 

believe it or not Wannadiesel is correct. But to get back to what you are really asking, I have heard of people using SD ford masters and boosters. How much effort will this take to swap, not sure you will have to search it
