I'm not sure i fully understand your post, but here goes anyway:

THe Dual master cylinders are sort of funky in that the secondary (for rear brakes) piston is often (tho not necessarily) SPRING loaded to the primary piston. That means that the pressure to the rear brakes could (tho not necessarily) be less than to the front brakes.

U mentioned a "bleed problem" that went away????
I'm assuming the the "bleed problem" u had was problems with bleeding the REAR brakes wheather before or after bleeding the front brakes AND no proportioning valve.

If the bleed problem persists (as i am assuming it to be) then bleed the rear brakes at the wheel cylinder bleeder screws as usual BUT DISCONNECT the line for the front bakes AT THE MASTER cylinder and use a recirculation tube from the master cylinder outlet curving back into the master cylinder reservoir.
