All of a sudden i dont have power brakes anymore. They feel like their maual, and I can still drive around but just with no power. I have front discs rear drums. checked brake fluid, checked brake booster. what else could of happened? thanks

Hose from intake to booster sprung a leak,or diaphragm in booster sprung a leak.

Or perhaps either the hose came off or you broke a fitting. That happened to me once....plastic went brittle after awhile.
