6 pot caliper rebuild observations
Got these at a good price and I am undertaking resealing them.
The smallest pistons in both calipers were the toughest to remove.
The dust seals were all shot. ...nothing new.
The anodising is slightly worn through ..all on the same 'face'. You can't feel it with a finger nail and in each bore it is only outboard of the oil seal. So I am not too worried about it. I shall replace dust seals though to try to extend the life on the castings .
All the ceramic pucks are in good shape. One came off the pistons whilst trying to remove from three caliper.
Anodising on all pistons is like new.

There is a caliper rebuild thread with lots of good info. It's about PCCB, but AFAIK red and yellow are the same basic caliper under the paint.
