When you pump the break pedal you are indeed affecting the vacuum in the system. Remember the booster gets its vacuum from the intake manifold. If in my van I pump the break pedal repeatedly, it affects the idle of the engine to a certain degree.

Bleeding each line at the caliper is you best shot to restoring breaks effectiveness.
