Take the inlet fitting out of the brake valve, there is an orfice right there in the valve and it is not uncommon for it to get a piece of crap in it. On your self adjusters, set them all the way back and make sure the little spring on them will allow screw to turn in one direction only. No need to bleed brake valve, just bleed brake themselves, run a plastic tube from brake right back into the oil filler and push the pedal, should get a good flow, 1 gal a minute. If you have a TA on tractor and it works ok in direct drive your pressure at mcv is good. If no TA you may need to put a gauge on mcv, should have maybe 240 psi to 270.
