Smaller mc will increase line pressure with the same poundage applied to the pedal. Same force, smaller area receiving It gives the mc more leverage on the same wheel caliper piston.

Or increasing the size of the caliper piston will work as well.

I have increased the caliper on my 115 benz with excellent results. I also did it with my old 71 bronco with excellent results. More power on the brakes with the same or less pushing.
