Reset proportioning valve

[charlieathediso]

Hey guys!!! New to the forum! Basically had bad wheel cylinder in rear. Replaced it and now no fluid to the rear. How would I go about re setting the proportion ing valve? Truck is a 78 c10. I heard you have to close the rear bleeders and open the front ones which have pressure and stomp on the pedal to get pressure to the rear? Thanks in advance
