95 Cavalier Master Cyl/ABS problems

My RF wheel will not bleed, it has no pressure. Nothing coming out from the master/ABS assembly either. The assembly has 2 bleeders. One in the front, which bleeds normally. The other is on the side at an angle. This one bleeds about a tablespoon once, then it's done. I changed the master/ABS assembly from another 95 and it did the exact same thing. I'm led to believe it's not the assembly, but who knows? Anyone ever have this problem? It's driving me nuts. I gotta deliver pizza in this thing and the only brakes I got is on my LF wheel, and that's only the last 1/4" of the pedal. Thank Ha'Shem it's a 5 speed.

you can get the correct way to bleed abs/module & brake system at autozone.com
it may be trapped air
good luck

Thanks for the tip. I've found several sources for the bleeding process including autozone.com, all are about the same. In the Delco VI system, there's 3 valves. Front for the LF, rear for the RF, and the middle is for both rear brakes. The rear valve is sticking? I think? It's the same on both the assemblies i tried. I'm going to open the valve manually. Anyone experience that before?
