I'm replacing the buna rubber AN o-rings in my brake calipers with Viton-A rings. I have purchased V75 and V90 rings. Based on an examination of nitrile (buna) specifications, the original rings have a "hardness" of 70, i.e., approximately equivalent to the Viton V75 rings.
Anyone have any experience/recommendations with which hardness to install?
Cheers,
Vac
