James, I've replaced my master cylinders a couple of times. There's not much
to them. Most likely the leak is a a pipe union or where the plunger enters
and exits the unit. I tried to rebuild my cylider the first time around. It
took a lot of effort and it still didn't work properly after I finished. So
I bought a rebuilt unit from Faspec in Portland, Oregon for around $79.00.
It had a new brass rebushed sleeve and has worked great. I replaced the
clutch master cylinder while I was at it also. Really, the worst part of
this job is the fact that it can be rather messy, working with brake fluid!
I was told to only use Castrol GT LMA brake fluid in the system. At one time
I used the silicon fluid and my system developed problems after about a
year. I don't know for sure that the silicone fluid caused the failures, but
it was suspect. Since using the regular fluid and restoring the master
cylinders I have had no problems (about 3 years now).
