Anyone help me with Part numbers for S3 caliper bolts
« on: April 21, 2023, 04:24:43 pm »
Hi all,

As in the title really, i recently purchased a set of rebuilt s3 calipers, and everything is good, except for the four bolts that hold the two halves of the caliper together.

I checked on etka, but cant find the part number for those bolts, only for the caliper itself, and the seals and pins.

Any ideas?

Do you mean RS3? S3 had iron sliding calipers. 2 Halves implies 4 pots. Should be standard cap head hex bolts.

No individual part number for them. They look like a standard torx cap head bolt though, should be able to find them at a hardware store.

Hmm single piston, so not sure maybe off some different model? For 345mm disks. I said 2 Halves but I guess three parts..

Possibly, if that's the case I may just clean up and reuse the ones I have, just need to get rid of the surface rust..
