Defective MC?

A couple days ago on the Festiva the brake pedal decided to meet the floor. It would hold pressure for a little bit then let go. Master cylinder right? So I went and got another from Autozone. I bench bleed that worthless thing at least twice so far. I probably messed with it 30 minutes to try getting the bubbles gone and finally gave up. What is does is only applies pressure to the front passenger side. I get very little fluid from the rear and absolutely nothing from the drivers front. It's almost like it wants to suck the fluid backwards. Not sure if I should return it or if I'm just not doing it right. I clean the portioning valve and it looks clean. I was hoping to get it done before it snows and gets colder again.. so much for that.

Never mind it's going back.. hell with it. Apparently it sorta common for bad reman's. I just read where one guy got 6 bad ones. I might just upgrade for new!

If you're only getting fluid pressure to, it sounds like 1 of 4 wheels, it's probably not the MC. Getting pressure to the pass. side from makes sense, as it is actually the shortest run from the proportioning valve. I suspect either the valve is bad, or you've got a ruptured line somewhere. Do you see any puddles/wetness under the car after pressing in the pedal a few times?

Leaks no anywhere. Fluid level stayed the same. I'm not getting anything into the lower line into the proportioning valve, just air. If I remember right that one comes from the front that I wasn't getting anything out of.

Finally have brakes! I returned the MC to Autozone and they didn't have another so I got my money back. Went to OReillys had to wait 2 hours but I literally had it installed and bleed in less than an hour after I got it. The OReilly mc is a cardone brand. I could even tell a difference bench bleeding. I could almost party now...
