Non-silicone brake fluids are an incredibly efficient paint stripper.

No it's not normal-they should be dry. Is that brand new or NOS. I had
the same problem with a Triumph master which was NOS (£90.00!!) and was
worse than the old one.

Doubt it. The master pushrods have a heimshperical or tapered ends. They
can work slightly out of alignment. I suspect the seals may be (a) aged
beyond use, (b) badly fitted or (c) replacements of poor quality and/or
the wrong composition.

Sounds ok but I would add a thorough clean off with panel wipe or
standard thinners before painting. Brake fluid creeps into all places
and seems able to hide in the pores of the metal.
Hope this helps you,
