I've been working on the brakes on the "new" FC-170. What a mess! :-)
When I pushed on the brake pedal, all five brake cylinders (4 wheel and the master) leak, the rear brake hose swelled up to about 1-1/2 times normal diameter and the 3/16 inch brake tubing along the rear axle oozed at several places where it rubbed against the U-bolts.
For grins I decided to weigh the dirt that I scraped off of the left rear brake drum/backing plate. 1lb, 7oz. In a way, the grease all over everything was good...all the nuts & bolts came loose without any difficulty.
The drum and backing plate are sitting in some cleaner.
The master cylinder looks clean, smooth and does not appear to have been honed.
The wheel cylinder is about .010 "oversize" already and has a huge rust pit about 1/2 the length of the wheel cylinder that is about .030 deep.
The brake fluid in the cylinder was more like gravy than brake fluid, so the pristine condition of the master cylinder bore is kind of surprising.
Once the brake drum can be handled without gloves, I'll see how much it has been turned down.
My first inclination is to get the Jeep so it will stop, get it to steer, get it to run [it runs, but I need to hold the choke closed with a screwdriver until I get the choke cable lubed up] and then drive it around awhile to get to know it....and then [when the bank account is up to it] pull the cab & bed off to work on it "seriously".
