Reply to "Early Goose rear Calipers from Fiat Dino?"

Any good machinist with a lathe can duplicate the plated mild steel pistons from 304 or other stainless steel, thus removing pits from rusting cutting the seals from your list of problems. For some reason, Euro brake calipers- including Ferrari and Porsche- nearly always use plated mild steel for their caliper pistons, while everyone in the US including aftermarket use stainless steel since 20 years ago. Curious...
As most know, I use aluminum ATE 2-piston calipers once on 911-S front ends, in the rear of our Pantera, and lost a seal from a pitted piston 5 or 6 years ago. Took a few days to make & replace all the pistons; rebuild kits are available but not pistons. Some refurbishers will acid-strip old pitted plated pistons, then touch-up weld, grind to size and re-plate with fresh chrome or nickel. VERY pricey!
