Hal,
Well, it is made from cast aluminum, as are your wheel cylinders, disc brake
cylinders, master cylinders, and servo. It is true that the surface can pit
from corrosion, as can the old cast iron type, mostly from moisture absorbed by
the hydraulic fluid.
I don't know what your friend has, but very few cars come with stainless
sleeves, and most other materials suffer from moisture in the system, which can
be prevented by regular flushing, and the correct Castrol LMA fluid. Some use
synthetic fluid, with pro's and con's too lengthy to discuss.
It is a financial, rather than technical, decision. If the walls are not so
badly pitted that a honing will clean up the surface without excessive material
removal, then it is a relatively inexpensive fix. New units, however, are still
available for all but the disc brakes and the servo, although replacement
servos from Lockheed are available at around $300.
A better design solution is the use of brass or stainless sleeves for the
bores. This can run about $65 per bore (sleeve only), and is available from a
number of sources:
