I thought I had taken pics right after anodizing but apparently not. Next step is to remove the anodizing over the PORSCHE lettering. These are sand cast and machined so even though this was done at the factory when first made, this proved more challenging than I anticipated.

Tools used. The pneumatic pen spins at 56,000 RPM. An amazing little tool.

Taped up and started filing away. Very uneven surface on this particular half.

After a little work and then cleaned up with the wire brush on the pen.

Finally time to get the seals and scraper rings in. Tumbled/polished the pistons and then lubricated the seals with Sil-Glyde, worked perfectly, I used a bearing press disc with some duct tape to press them in place. The pistons are stepped to reduce contact with the pads which reduces temperature transfer from the pads to the fluid. Front calipers, the step is on the lower side, rear calipers the step is on the top side.

All done.
