non-eclipse related brake question

So my dd is starting to go down hill. I have a 95 accord that is my work vehicle. Under low idle the brake pedal will completely go to the floor, and thats the nly way to keep it from moving is to hiod it. But if you r going 55-60 and around 3k the pedal is firm...is this a booster issue? I have fluid in my MC and no leaks present. I still need to take the wheels off and check the pads but if i recall they were changed recently. Or does this sound more lke air in the lines? I figured not because the pedal is firm when the motor is under a lheavy-medium load, and goes to the floor under low rpm conditions, mainlly 7-800 rpm. I checked the two hoses coming from the brake booster and their is no visible signs of leaks anywhere or cracks. Is their a way to check the brake booster to see if its working properly?

It could be something as little as a vac leak check the hose coming from it to the intake or the check-valve on the booster

how would i know if the valve is bad..would it be stuck in a certain position

its supposed to close to keep a vac in the booster. you shouldnt be able to blow air in i believe. If you have a vac tester you should be able to put a vac on the booster and it hold it.
