Check the master cylinder and see if the fluid is leaking out the back and into the booster. If you're adding once a week, that's a big leak and should be relatively easy to spot.

I had a 94 Thunderchicken and had the same delema. I hunted for months, finally found out it was leaking from the front left caliper. just a slight drip only when the brakes where pushed firmly. What I had to do was pull it somewhere that you can lay paper down under the tires/ lines ect. and pump the brakes and look for drips/leaks.

Good luck

Sometime when the master cylinder leaks the leaking fluid is sucked into the engine through the vacume hose and you never see any dripping . That's where I would start looking ( the inside of the hose will be wet ) , then if all is ok there pull the tires off and look at the calipers ....But my money ( what there is of it ! ) is on the master cylinder .
