When bleeding brakes (new system), do I need to do anything with this hold-off valve?

I've opened it up all the way to bleed the rears. Do I leave it open, close it 1/2 way or close it completely to bleed the fronts?

I'm constantly getting air out the fronts only. Going to bench bleed the MC again (on the car) and try gravity bleeding.

Kind of running out of options on the fronts as I have gone through gallons of brake fluid and keep getting air!

Oh yeah, SSBC disc brakes with new power booster and MC. Original 10" drums out back...

Thanks

Is the bleeder on the caliper on top or on the bottom? I'm not sure if they will mount upside down or not but if that's the case, that would be a problem.

to take care of the front discs the rear adjuster can b anywhere. Prob is where is the air being drawn back in in the front half. Once I had the bleeder screws open too far when bleeding & when helper inadvertently moved the pedal back a slight bit it drew air back in b 4 I closed it & told him to let off the pedal. Yes I'd repeat the bench bleed then RF then LF & check the bleeder screw(s) EDIT sometimes pumping the pedal fast several times & holding it then you opening the bleeder works good to agitate the fluid & get the bubbles up to the top

Thanks, I'll try again with these tips...

Mopar Country, Yes, bleeder screws are correct. I wish they weren't and that would solve it!
