You are simply wrong about wheel cylinder sizes. The fronts are always larger than the rears on cars and light trucks, because the fronts do most of the work. That rule gradually reverses as vehicle weight increases in med/heavy trucks, RVs, etc.
The fact is your plumbing is wrong, and could be dangerous, because the loss of the rear circuit could result in marginal (or no) front braking due to insufficient fluid volume.

I will look into it and if necessary, switch the lines. Thanks Bob. Not trying to argue here, I do not claim to know it all and my experience has been with newer cars. Always thought drum systems used the same size wheel cylinders front and rear. As a side note.. I did loosen a rear brake line and had sufficient braking to stop the car.
