Which FZJ80 master to buy
I need some help from you guys that have done a rear disk brake conversion. I recently done a conversion on my runner and for the most part, they work pretty good. Problem is, my pedal doesn't build pressure till about half way down. At that point it firms up pretty good. Go for a second pump and it's perfect I'm pretty sure the rear caliper pistons are pulling in slightly. I believe a residual valve will take care of my problems here.
My dilemma, I can't find a valve. I found many 1/8 npt valves but no adapters that will convert to m10x1.0 inverted. I found one valve that fits m10x1.0 bubble but in my experience bubble flares are a bear to seal.
My second option is an FZJ80 master cylinder that apparently has a residual valve built in. Unfortunately information on these things seems to be very inconsistent. From what I understand, abs trucks had rear disc and non abs had drums. Apparently some had residual valves front and rear and some didn't but no real indication of what is what. Plus everybody says to use a non abs cylinder but they are apparently the ones with drums which doesn't make sense to me.
Can anybody clear this up for me before I pull the trigger on a new cylinder? Currently I'm looking at part# 47201-60540 which is listed for a 94 FZJ80 non abs USA truck. If anybody knows a source for a regular valve and/or fittings to work too that would be great. I think I would prefer to go that route instead as the 4runner master otherwise works fine.

I am just getting into learning about the 80 series Land Cruisers so I don't know.
If you haven't already, check out the 80 series section on IH8MUD. They will most likely know the answer. https://forum.ih8mud.com/forums/80-series-tech.9/
If you do find your answer, please post it here!

Yeah, Ih8mud is where I've been spending most of my time lately. That's where the majority of the information I have is coming from but it's all still been pretty indefinite.

And I intend on doing a write up once I get everything squared away. I still gotta get the pedal feel and the parking brake fixed up. I got the parking brake working right now but its a pretty hokey method. Gotta make a custom cable.
