Kisner, I am on board with you not using the booster, it would be nice but I'm sure you could be ok without it.

If you decide to go with the old drum distribution block then you will get equal pressures at the wheels and not give you the best braking and possibly not enough fluid to apply good pressure on the discs. This answers your other question as well, the reservoirs are different sizes because the front discs need more fluid to operate, just compare the piston size in a caliper vs. wheel cylinder.

The front discs are the primary stopping system and need more pressure, so if that is through a dist. block or a adjustable valve they need more than the back drums.
