A bit of research suggests that initial pumping of master cylinder may have damaged the piston rubber if there was some corrosion in the section of the bore that is not swept under ormal use.

Probably need master cylinder kit, but need to lightly hone the bore before putting in new rubber.

I have a hone down here... if you want to use it and do the job down here give me a call.

Dont open bleed nipple too far, it only needs a quarter to half a turn open.

It roughly goes like this....

Fill master cyl,
Pump, pump, pump then hold lever down,
while holding down,
Crack open bleed nipple,
Pressure should squirt out,
Nip up brake nipple.
Release lever. Check fluid level.
Repeat
The brave may not live long, but, the cautious do not live at all.
