Master Cylinder issues...lol

[hdheritage97]

I have a sort of unique problem with my master cylinder, actualy a couple of problems...lol. I had to take my rear out of the car due to a tire rub problem I was having. Oh yeah, I have an EM car. Anyhow, I was rubbing inside driver/outside passenger on my rear tires. I of course assumed that the fellow I had bought the car from had not located the mounts properly when he relocated them due to his using a custom made Ford 9" IRS setup. I took out the rear, which entailed totaly disassembling it to get it out and I of course had to disconnect the brake lines. It turned out that the trouble wasn't in the mounts at all, but in the body itself and it required some machine work to the rims and the IRS unit to try and solve the tire rub problem. In any case, when I put it back in, I found that I can no longer get any pressure from my master cylinder. I have tried bleeding it with it in place on the car but can't seem to do so. I continue to get air in my bleeder and can't figure out why, and also what appears to be water, but from where or how, I have no idea. To make matters worse, I would just pitch the thing and start over with a new one but I have no idea who makes the damn thing....lol. I have Jag suspension in the front and that was what should have been in the back until the previous owner went with the Ford IRS. Sooooo, I'm thinking maybe it's a Jag unit but of course I can't find a pic of a Jag setup anyplace. I guess my question is this, any ideas why I can't get pressure and I keep pulling air ? and does anyone know of a decent unit that will work in place of what I have ? I am running manual brakes, inboards in the rear with mid size GM calipers, Jag's in the front. The current setup has two seperate units mounting to each side of the brake pedal. Do I have to use this type of setup or can I go to a single piston ? A local parts shop suggested I go with a '74 Corvette unit that's made for manual brakes, it's like $16...lol...but the cost really isn't an issue, I just want to get my car back together before summer comes and goes...lol. Any ideas would be most appreciated.
