The remains of the fluid in the brake master was similar to wax. The remnants in the clutch master was lumpy like curdled milk.
It would seem engineers in the late 60's - early 70's either didn't yet appreciate, or care about dis-similar metals. I have been surprised at the number of parts where aluminum and ferrous metals are in contact, and therefore have very advanced corrosion. The cap to this assembly is a good example. The body of the cylinder is cast steel, the cap is aluminum, and (had) a steel stiffener plate sandwiched between it and another layer of thin aluminum above. Luckily, the resulting corrosion worked its way outward rather than inward, so the primary cap is still in decent shape.
I also finally got the pedals off the floor and wire brushed.
I have been scratching my head on this one for some time. There are four set pins that hold the assembly to the floor, but the pins (due to mushrooming of the heads) can only be driven one way - towards the firewall, which sits only 2" away. I drove the pin that limits the rotation of the whole assembly in as far as possible, then cut it off flush and drove it through the rest of the way with a punch. At that point, I was able to rotate the pivot shaft and drive the remaining pins out the way they went in.
