Low vacuum motor=low pressure @ rear calipers?

My motor has a large cam and my boost guage tells me Im pulling 10" of vacuum. The brake pedal will not go to the floor when we bleed the brakes and the fluid pressure at the rear calipers seems light. Could this be due to low vacuum? thanks

Re: Low vacuum motor=low pressure @ rear calipers?

could be, your not getting enough assist from the power brakes, so less fluid will move.
