Power Brake Problem

i have a new problem today and cant seem to figure whats wrong. my 1978 c10 has a booster and never had a problem with them before. yesterday i noticed when i press the brake pedal it went all the way down and didnt seem to grip. release and pressed again and gripped. now today it acts as if it had a lot of air in the lines. it doesnt because i bled the brakes this morning. do you guys have any ideas what could be happening? i dont think its safe to drive as is cuz the pedal will go all the way down without gripping now. any help is appreciated. Thanks.
