Vintage 911S Caliper Restoration Thread

Well they're clearly 69-71. I don't there is any other difference you could rely on, so I reckon you're safe using those on your 69.

Yay

Expect them soon for a resto Eric

Clyde,

few pics of early calipers i have, you can check differences, i dont think that the digit stamped is a date ;-)

Not worried about vintage, but was curious as to the significance, if any, of those stamped numbers. I sourced these back in the mid-eighties. There are also smaller markings as seen below.

Sherwood, you should use SC pads with the Ti backing plates. Those are Carrera pads.

The very small numbers on the nose should be the forge number. If you look really close you will see... a fox as in "Fuchs" being the forger. I believe the square with the numbers inside is the mark of the final inspector or line. There are no real date correlations I've seen with those numbers.

I like OliveR's first picture. It shows(L to R) an early 69, late 69/early 70 and a later 70 with the circles without the "X". It also shows how different all of these S-Calipers are from various workers. Some had a more shaved (industrial belt sander) top and some had hardly any sanding at all. After the units came out of the forging, the workers used the belt sanders to remove the flashings and rough edges. A short industrial polish and they were off to the machine shop and anodizer.

Clyde, you're looking at late 69/early 70 for those calipers. Sorry John, 1971 would have a circle in the top with an "X" stamped in the circle.

Cool. And the X means the later pistons right?

Eric,
Those are A caliper pads, thinner friction material than S pads. Yes, to fit our Ti Brake Shields (TBS-1) in the S caliper.
