The vacuum assist (booster) makes no difference. If it worked with the drum brakes, it will work with the discs.
When swapping to disc fronts, it's best to use the '69-'72 A-body disc/drum master cylinder. Don't forget to also pull the prop valve from the Buick-on-Chevy brake system and put it on the LeMans. On another note, you can swap out boosters to the '78-'87 10 inch dual diaphragm booster. Better response and pedal feel. Check my web site here.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
