Hi Richard,
        I sent my m/c off to a reputable (I thought ) rebuilder for a =
complete rebuild and installed it back installed it in the TR6.  As I =
recall it worked fine for a short time and then on day I was puling out =
of the garage and the brakes totally failed.  The TR6 rolled int my P/U =
truck dented the door, and pushed in the front o the Tr6 hood. A very =
expensive afternoon. I sent the m/c back to the rebuilder as I had time =
to kill while the body shop fixed the TR6.  They rebuilt the m/c again =
gratis and I reinstalled it.  After about 8 months the m/c started to =
fail again, but slowly=E2=80=A6 I replaced it with a new Girling and it =
has gone several seasons working fine but now I=E2=80=99m getting the =
slow sinking pedal. Before replacing it again I am going to replace the =
seals myself.
          Although I=E2=80=99ve had good luck with several rebuilt =
components including starters, carburetors, shocks, and distributers,  =
I=E2=80=99ll never send a master cylinder to a rebuilder again.
        Best,
        Bob
