In a defect-free world, no you shouldn't have to do anything.
The only other thing I had time to do was throw a one person bleeder bottle on the rears, looks like there a good squirt out of there but not a lot of fluid in that squirt.
What would cause that? Its like if someone was holding the pedal and I cracked the bleeder it would squirt out but not as much fluid as what the fronts would have.
This is what prompted me to bring this up. If nothing else cures the problem- I think you should look to be sure.
The last statement above could also be taken to mean there was insufficient volume
as opposed to pressure. Like if the MC were a disc/drum unit, having less volume for the rear drum brake cylinders than a disc brake caliper requires.
Who knows- when all's said and done, you may just need a bigger booster.
