I had the same problem on a 65 Gto were thy power all along ? I was told my master was a manual set up put on the booster and that's why it was so sensitive ? That was. 25 plus years ago so. Only going off memory

try to just remove to vac form the booster one and see what it does ? I cant 100% remember why mine was like that too tap the brakes and all four would lock up. Is the booster for a single vs dual master the same ? is the Booster for a disk vs drum the same ?
