I'm rebuilding the rear Girling calipers on my '79 244, but the pistons are scratched and marked and need replacing. The rest of the calipers are OK.
They are 38.1mm diameter x 28.8mm height.
I think they are Volvo part number 685331, or Protex 090P0022.
Seems these are available from the USA but anyone know if there's somewhere in Australia to buy these at a reasonable price? I've seen $140 per piston which is just a bit rich.
Alternatively I've seen FCP Euro have complete rebuilt aftermarket calipers by Centric for cheap, wondering if this is an option (even paying the core charge is still a good deal).
