If its really not using any brake fluid, as you wrote, then I'd hold off on
rebuilding the booster.
All the pumping you mentioned sounds like air got into the system, probably
from sitting idle with an empty reservoir. The fact that it got somewhat
better with usage sounds like some of the air worked its way back up the line
and out. Try bleeding it first, thouroughly, to get all air and moisture
out. Then check for vaccuum leaks in the hoses and intake manifold gasket.
An Alpine that's been sitting for a long time WILL need a complete overhaul
of the brake and clutch hydraulics soon enough, but you might as well get
some miles out of what you've got before spending the big bucks on a booster
kit.
