Vacuum help

We installed power disc brakes (under cab) last year. The old flatty doesnt quite have enough vacuum to keep the pedal constantly hard.What kind of secondary vacuum cans do you all use?

I have the same situation and I've been exploring adding a vacuum pump.

Does your intake manifold have two vacuum ports, the one for wipers and a separate one for PB's? The one for PB's is much larger, it's the one pointing straight back.
