cheak your brake fluid level if you keep bleeding eventually it will leak out when it was already low

changed your title. no one was going to come in here because of the old title.

You more than likely have a fluid leak in the rear or in the rear hard lines. Be sure your rear calipers are working and your brake hoses are not ruptured internally creating a bulging of the hose.

How would I check if the hose was internally ruptured?
I tried bleeding the breaks 5 times already, changed the MC and changed a caliper.....

You have to have someone press the pedal while you go around and inspect the hoses. If you replaced a caliper, was it by chance a rear? If it was you need to ratchet it out so the pads contact the rotor by activating the parking brake and releasing it about 50-100 times or you can do it manually at the caliper itself with a wrench or suitable prybar.

Replaced the caliper on the rear drivers side. Had someone sit there and press the peddal. My emerg brake has never worked since I've owned the car, 3-4 yrs. I dont know if it actually works, I dont want to activate my emerg brakes and then they're stuck on; I dont know how to release them if that was to happen:_
The car is up and running now, the brakes work- but they're still spongey. Another question: The car has been sitting for about a year; What could it be that is making the car want to stall? I've had it running on 94 oct gas but it still wants to stall once in a while.
-Thanks

I personally would be looking at the forward O2 sensor on your car then go from there.

does it have a MAF sensor? if so, clean that.
Same with the IAC.
How new are the plugs and wires?
