Re-Anodizing Alloy S Calipers

[jkolk]

Does anyone have experience getting this done? How do you get the guide pin out the fits up in behind the piston?

Or does anyone know a shop that will refinish them?

It would be interesting to see if this is possible. I don’t
think the calipers were originally anodized. Yes, there
was a very thin coating (similar to on a Fuchs alloy
wheel but thinner). That coating rapidly changed from
clear to a light amber with heat and age.

If your goal is to reproduce exactly the correct finish,
there are 911s with un-molested original finish calipers.
You could do a great service by investigating and
publicly documenting this.

Here is one I imaged last week.



Clearly it has had the surface cleaned.

This is new old stock

Bill,

WOW

What I’m used to seeing in service were probably coated with either a paint (laquer?) coating like the Fuchs or the Tectyl “one-season” undercoat that Porsche sprayed everywhere under the 911.

NOS spare parts almost certainly weren’t coated with anything.

If I were judging Manhattan, I would expect to see degraded original finish and coating (or likeness) for a close to perfect score.

Best,
Grady
