I have nearly the same problem on my V2C. 2 seasons ago I noticed
something dripping from the vent hole in the bottom of the fuselage.
Until then mybrakehad been rock hard. Inspection showed that yellow
brakefluid was leaking from the master cylinder and gum had formed
around the master. Fluid probably 14 years old. I could not find a
revision set and decided to buy a new Magura master (from the
motorcycle store, used on many BMWs). Instead of a 20mm master, I got
a 16mm master.
The 16mm master should only give a bit more travel. Re-installed and
had the same described spongyness. Took the Cleveland caliper apart
and observed significant corrosion on the caliper, less on the piston.
Sanded carefully a bit, installed new O-ring and re-mounted. Still the
spongyness, even after pumping a pint of new clean fluid both ways (up
and down).
Part of the problem is that the piston retracts a bit upon release of
thebrakehandle, instead of taking new fluid from the master
reservoir to fill the void.
I need to do more work before the season starts

Question to Bumper:
Can the brass liners and anodized piston be retrofitted ?
Where ?

Good luck with the brakes. *You may want to look at replacing thebrakeline. *The one SH used was disintegrating & thebrakeworks much
better after replacing it with a stainless braided unit. *The Hot Rod
crowd has great sources.
