    Welcome to Motor Vehicle Maintenance & Repair! You replaced which part? The hyrdroboost, or the brake master cylinder? Have you opened the brake lines at all, anywhere along the way? – Pᴀᴜʟsᴛᴇʀ2 Mar 30 '19 at 21:51

Sounds like a air in fluid or a brake master cylinder seal inner issue. Was the correct booster installed also could effect the outcome. Oh I’m sorry I just remembered on some of those older Chevys manually bleeding is not sufficient u have to get in with a scan tool and run an auto bleed in the abs motor. Hope this helps.
