Princess 4 pot calipers

[KKson]

Just won a knackered pair of Princess calipers on flea so was going to send across to Bigg Red in Worcester for a rebuild and electroplate. Standard new pistons or stainless? £30 in it. Any one have any views? And yes I know they're a pain to bleed......

Stainless in mine.

When I rebuilt mine many years ago AP sold me a set of aluminium pistons.
I've never had any problems bleeding them - I change the fluid every year - use an Easybleed. I flush through all 4 nipples on each caliper, although that probably isn't strictly necessary.
