Bruce,
After Stainless Steel Brakes stopped offering them I found that Andy
Kress of Performatek had the proper set up. I say that because it
matters where the rubber seals are carried as to whether the cylinder
is brass or the piston is Stainless. The rubber needs to run on
something that wont rust because the rust will destroy the rubber.
Andy does not sell pistons separately as far as I know. But he has
the right parts, is accessible, knowledgeable and is involved in the
Alfa community.
White Post can do any kind of restoration and they are good. However,
when I last inquired about stainless and brass they felt there were
multiple approaches. I don't agree with that approach but still have
(Saab) parts headed their way for rebuilding.
Finally, machining pistons is not difficult. I don't think you would
have to look too far to find a machine shop to do one in stainless.
Looks like a job just past lath 101 to me.

Subject: [alfa] Replacement brake caliper pistons
Does anyone know of a source for new brake caliper pistons for ATE
105 brake
calipers? I tried the usual sources; IAP, Vicks, Centerline, Alfa
Parts,
etc. without success. SS units would be very nice.
Thanks,

Agreed that caliper pistons are not beyond lathe 101. IF you have a
lathe, and happen to have some around, Ti is a whole lot nicer material
than even SS for caliper pistons.
However--machining ANYthing out of Ti is in a category more like lathe
305, as it's rather nasty stuff to cut on. Rake angle, speed, feed, etc.
all have to be JUST right, and it's not really a job for a 'hobby' grade
machine tool.
