An ADJ PPV (which it is not) is meant mainly for a DISC/DRUM SWAP.

It would only be used (if needed) on four wheel drum where one has used different year/model wheel end brakes from different vehicles to try and balance the system.

If you are adding a dual rsvr MC to a four wheel drum car with OEM wheel ends, there is no need or benefit (IMO).
