Nice work!- I haven't touched the brakes on my 72 Blue 4x4, but I need to eventually...
I wanted to get the body mounts worked out first - done.
At some point I will check on the brakes - the PO 'fixed' them prior to driving it to me from Columbus (some 200 miles or so) - so it is stops - just takes a bit of time to do so...so I know it needs checked.
The PO replaced the booster, MC (with the wrong one - not for front disk), and a rear wheel cylinder.
I am not looking forward to snow here at all - I will likely be moving my 'garage cars' into another storage place for the winter to work on the 72 4x4 this year while the snow flies in my garage.
Keep going with the updates - even small steps towards the finish line get you closer than not doing anything at all.
