Our older cars ran 3/4" front and 5/8" rear master cylinders. This can vary depending on what size calipers you have.
The theory is to work out the ratio of piston area between the master cylinder piston and the caliper pistons. The rear calipers are single piston and the front are twin or 4 piston so have more surface area. Oposed pistons calculate as a single piston in area so for a 4 piston calipers you take the total piston area and halve it they are opposed pistons.
When you know those ratios you can then work out the difference in ratios brtween front and rear and adjust the size of the cylinder to get you in the ball park of where they should be for the weight of the vehicle etc.
The balance bar is really just for fine tuning the front rear balance.
