Drum brake vs disc brake dual reservoir MC

I finished up the disc brake conversion... or so I thought...

When I converted to a dual reservoir MC for 11" drums all around, the MC ports were labeled for the front and rear circuits - the rear port for the front brake circuit and the front port for the rearbrake circuit. This made sense to me in that one wanted the front brake circuit to see line pressure first to help activate the bigger front wheel cylinders.

Now with this disc brake conversion, the disc / drum MC has different size reservoirs. The MC ports are not labeled. The rear reservoir has less volume than the front reservoir. Since the disc brake caliper pistons are larger than a drum brake wheel cylinder, does it mean that the larger front reservoir is for the front disc brake circuit?

If so, I need to replumb the brake lines!

 

the larger reservoir is for the disc because of the larger volume used by the disc brakes
