EK1 brake upgrade

[Surrufus]

im planning to upgrade my EK1 CXi rear drums to discs
i know that my current front discs and calipers are the same size as the EK4 equivilants so i dont need to worry about those
the question i put to you fellow ozhonda members is as follows:
do i need to upgrade the EK1 CXi brake master and booster cylinders or are they the same size and capacity as the EK4 units?

You shouldn't need too, but you should change your proportional valve.
