One of the last things to fix on my omni is the brakes. The car sat for 5+ years and the fluid was black, one of the front calipers was stuck, and the master cyl "crunched" when you pushed the pedal in. So I put on both new front calipers/pads/rotors/rubber lines, replaced the rear wheel cyl, replaced the mc, and when it was all apart i blew out the lines and cleaned the rust out of the prop valve. It's all back together and I bled about 2 big bottles of fluid thru it. I adjusted the rear drums when I had them apart changing the wc. I did not replace the rear drums/shoes/hardware because they were in good condition. All I did to the prop valve was take the sensor off, the two caps on the sides, took the springs out and flushed it out with brake clean. There was a good amount of rust particles in it, but was in otherwise good shape.
Now my problem, I can't get a firm pedal! It goes strait to the floor with no pressure, you cant even pump it up any. I have been over every inch of the system and it has no leaks. I get very good flow out of each corner, and I have bleed it 2-3 times. It really has me stumped. Could the brake booster be bad? Did I fubar the prop vale by taking it apart? I really would like to put a few miles on it before SDAC, but would settle to just drive it there! Any local help would be apreciated, cold beer is waiting.
