My 1971 J-4600 currently has drums front and rear on 5-lug Dana 45 and Dana 60 axles. I'm considering removing the entire brake system and replacing everything with disc brakes all around, stainless lines and a hydroboost conversion to get rid of my vacuum booster. I'm planning to go with BJs for the front kit and TSM for the rears.
I'm hoping for some opinions on proportioning valves. If I'm reading correctly, the junction under the driver's feet my FSM calls the "front tube tee" will need to be replaced with a prop valve that will work with the discs. Would it be better to go with a later model prop valve that will handle this function automatically? (I'm planning to install new, not a part from the boneyard.)
Or would it be easier or more effective to install an adjustable proportioning valve instead? And do I understand correctly that if I use one of those adjustable valves like the ones BJs sells, the front and rear lines would then be completely separate, with the primary outlet from the master cylinder routed to the front and the secondary to the rear?
I haven't done a brake project this involved before, so I'm just trying to get it all straight in my head before I start ordering parts and taking things apart.
