Look up "diagnosing hard brakes." Could be lack of vacuum, check valve, booster. FYI the master cylinder should have been bench bled, if not you likely still have air in the system.

Hello everyone, just to fill you in this van had an extra brake line installed for a trailer towing package. That was the main problem with the braking system. Ounce this line was removed and the brakes re-bled just to be sure everything works fine. Thank you very much for your advice and what to look for. I raise a glass to all of you. Cheers !!!!!
