Will do WyrTwister. Last night I did pump the brakes with the engine off and the pedal was harder to push as it should. Turned on the engine and pedal goes down. I tried duplicating the problem and no results. Fluid level on the master cylinder is good and no signs of leaks. I did see your post petrified.rabbit but I used a spay bottle with water to check for vacuum leaks. Did find one and fixed it but it was at the PCV valve connection. I soaked the booster hose and the other ones but I couldn't hear anything. I'll report back with my findings with the propane one. I may even try it with carb cleaner. Yesterday I went to Harbor Freight and picked up a vacuum gauge just to measure how much vacuum I am getting off the engine. I might even try to hook it up to the car between the engine and booster and tape the gauge to the windshield. Then I will drive the car around for week. Of course this is if I don't find any leaks and having the same problems after replacing the hoses. There could be a chance that the engine is not producing enough vacuum. So if and when I exhausted all my options then I will install a electric vacuum and tie it to the booster. This is of course the last resort lol..
