I think a little creative use of heat-shielding might help both problems on
both cars.  I was really, really surprised at how hot the MC was getting on
my car as a result of the radiator cooling fan.  A few good heat soaks like
that and any internal problem with the MC is going to be magnified.  If you
look at an '87 5KCSTQ, you'll see that there's a lot of heat shielding and
ductwork all over the place, but this is one of the locations where the heat
from the rad. fan is directed almost straight at the brake master cylinder.
I think a little creative venting and shielding might help it live longer --
maybe a small duct that pulls cool air in along with the fan, and a shield
that deflects the blast a little.  It shouldn't take much, and as long as
the rest of the underhood temperature-management hardware is working I can't
imagine it'll hurt anything.
