Two wheel cylinder brake question

[Bonham]

Can anyone tell me when you have a two brake wheel cylinders on rear hub, which one has the bleeder? Top or lower one? The way it is now is the bleeder is on the lower wheel cylinder. Although I have a schematic the shows the bleeder should be on the top one and another schematic shows two lines feeding each side so each one would have its own bleeder.

Bleeder screw always gets positioned as high in the system as possible. If you had a upper and lower set of cylinders then the upper one should have the bleeder.
