Car stored now running. Had to replace master cyl. Cylinder came off but piston came out of cyl and remains firmly protruding from vac unit. Can't tell what's holding it & do not want to cause damage. Anyone with knowledge of this AC Delco unit ??
That piston is part of the booster. You need to get a shop manual. Will save tons of time in learning & possibly destroying something in the process.
