I am in process of restoring my 86 svo. I have replaced all brake components master cyl, prop valve, all lines, rotors, calipers. I can get fluid all the way to the rear calipers but cannot get fluid out the bleeder screws ( russell bleeder screws) I can get fluid out the front brake bleeder screws but nothing out the rear. I know it doesnt make sense but I am hoping someone has a solution.

try a factory bleeder screw. if not loosen your current bleeder enough that fluid should come out by the threads.  that will tell you if you have fluid getting into the caliper and may have a bad bleeder

I ASSume that the two rear BS's (bleeder screws) are pointing predominantly up? If not, you may have the calipers swapped (left one mounted on R/H side and vice versa). If they're oriented correctly and won't squirt any fluid when applying pressure to the pedal, I suggest removing the screw(s) altogether and retrying. If still "no cigar", you'll probably need to remove the caliper(s) to determine if the hole is plugged or whatever is denying the fluid from exiting.

By the brake bleeder kit from Harbor Freight that uses compressed air. The best tool out there for not only bleeding brakes, but flushing the system. The vacuum it creates pulls the fluid through.

Thanks I used a prop valve from national parts depot I think that may be the problem am going to take the line off of that that goes to rear axle and see if getting any fluid. And thanks will go to harbour freight on weekend and get that bleeder kit

Keep us up to date  curious to know what the solution is.   I had a similar issue that one new caliper would not allow me to bleed the brakes on one side. Found the brake bleeder screw was not drilled correctly

I took out the russell bleeder screws put in normal bleeder screws. I found that the prop valve was stuck so as my son was pumping the brakes I was tapping the side of it with a hammer. It recentered its self and I was able to bleed the rear brakes. Wont know if it holds until I get the car running and take for a test drive. ( at least another 6 months) But I will have one hand ready for emergency brake just incase. Thanks to everybody for their help.

You won't need the parking brake to stop as long as the fronts are working.
