I'm changing the the 3rd gen power steering and hydroboost to 4th gen setup. My question is related to the brake master cylinder ports. The 3rd gen has the larger fitting toward the front and the 4th gen has the larger fitting towards the rear. Are the front and rear brakes lines fed from the front and rear ports on the on the 3rd and 4th gens, or are they the opposite of each other? I have the cut the lines and change the fittings and I'd like to put the lines from the 4th gen master to their intended brake control path.

Maybe someone here can help. Feed rollers moving too slow in forward, but fine in reverse. Tachometer controlled Solenoid is good. Hydropressure is good at the pump. Feed control valve and mainshaft looks good except for the Detent spring valve. The travel isn't hindered, and it holds position fine, but it's a little corroded, and so far that's the only thing I've found wrong with it. I'm trying to source just the detent, but so far no luck. I can get the whole block but it's 800 bucks. I don't want to spend that unless I know that the issue. So far I've found no fluid bypass anywhere. Unless there an issue with a hose lining, or something I'm not thinking of. I've pretty much narrowed it down to the valve block. Since the travel looks good, I'm not sure the detent is the problem. Fluid doesn't reach that part of that shaft.

My cousin took the photo. But we're both stumped.

2006 5.9 4x4 g56 mega cab. I bought it in 2014 with 172k from the original owner. He put a clutch in it before I bought it and that was the only real repair he ever had to do. It was a dually but i switched the wheels out after a few years. Living in the mountains is not ideal terrain for a dually. I had to replace the injectors at 300k and still have the original lift pump. I've also replaced the clutch at 400k. Other than normal wear and tear (ball joints, alternator, ac, u- joints, etc.) I've only done oil and filter changes . It's been a great truck and has paid for itself many times over. If someone offered me what I paid for it, I'd turn them down. I'll probably never let it go and just be buried in it one day. I guess it's time to order a high mileage club badge.
