ATE Front Caliper ID Help Needed - wrong size rebuild kit!

[Topher39]

I just got into rebuilding me front calipers on my 1969 w115/220 - They are ATE Calipers, I thought they were original to the car, but now I don't think so. I purchased a rebuild kit, careful to get the ATE and correct year. The metal Dust Shield for the piston fits but the rubber dust shield is a bit too large for the fit to the caliper itself, and the inner square O ring is too large for the interior of the caliper - UGH

The only numbers on the ATE Caliper is a large "14" and the number 43 on one side and the number 164 on the other. The Piston Diameter is 57mm

I would like to get the correct rebuild kit - any help is appreciated

A picture of the calipers might help - perhaps someone can identify them for you?

However google came up with this for the search term

"Mercedes ATE caliper piston diameter 57mm"

Does any information in that web page help?

Thanks for your feedback. I ended up contacting ATE and a customer service rep from Europe called me back within an hour. They told me a specific rebuild kit to use for the caliper. Rock Auto is great but on the rebuild kits (of which they have many) are not always correctly labeled for a specific application.
