is it a new master? Did you bench bleed it before installing the lines?

so you bought the car with this problem? Or if not, what did you change? The title of the thread makes it sound like you just did an sn95 5 lug swap and now can't bleed it.
I would start by bench bleeding the master.

make sure the prop valve is set to full + or wide open when bleeding.
a pressure bleeder like a motive pressure bleeder would also make it far easier.

Check to see if the stock prop. valve has been gutted

BOOOOO! My account got closed for good now! The least I could have done is shown some respect and sent an apology letter like a man. Instead, I tried to sneak back in using a fake account like a weasel and got kicked off this free website for good.

the stock prop valve is located below the master, there's a bolt on the front of it, unscrew it and if it's been gutted nothing but fluid will come out, if it hasn't then there's a spring and some other crap that needs to be removed.

probably not, I don't think the stock prop valve restricts flow to the rear line, it just leaves some pressure in that line after you let off the brakes so the drums hold adjustment.
What I think is happening is your lines all have so much air in them that whatever method of bleeding you are trying isn't able to push the fluid past it, you really should try bench bleeding first.
also make sure the bleed screws are facing up on the calipers, sometimes unbolting the calipers and hanging them up higher than the lines helps too.

id open the rears take the bleeder screw all the way out see if you get flow out when you mash the brake before assuming the brake booster is bad. if nothing then move to the next spot which would be right by the fuel filter there is a rubber line that goes from the hardlines on the body to a block that the rubber flexible line is attached to by the rear diff. un do that and try to get fluid pushing out there is still nothing then follow the body brake line to the proportion valve and undo that there...if no fluid come out then to the stock proportion valve below the booster booster last....just my 2cents been there done that......

what part of the bay are you in? Depending on how far you are i might be able to take a look.
If you feel like re-bleeding the whole system, you can undo the lines at the master cylinder and get some plugs at the auto parts store. Plug the two lines and hit the pedal. if it stays stiff, you mc is good, if it goes down then you mc is bad.

additionally, do you know if that is a stock fox mc? if its not a 93 cobra master cyclinder or an sn95 mc, i believe it wont work right since the foxs other than the cobra were all drum in the rear. i could be wrong on this though, that's just what i have heard......

I know who's car that was. You have a 93 cobra master cylinder you have the 3-2 port conversion but I believe you have the stock ppv still there lol. Your boy p hacked that car together...He always had brake issues since he did that 5 lug and he thought bleeding them every so often helped. I remember when I drove that car around the block the pedal hit the floor And he said to pump it. Just do a sn95 booster and master that's what I did to all my foxbody's with discs work great.
