Hi All-

Re:>I plan on changing out to the higher temp synthetic transmission fluid
Quote:
discussed here (Mobil 1 Synthetic ATF) and in addition will change
over to the Viton O-rings

Doing research leading to having some brake seals custom made for a different aircraft I discovered that Viton seals are not as durable as nitrile in reciprocating applications. This is, of course, precisely the situation with the brake piston / cylinder seal. I can't quantify the degradation of seal longevity with a switch to Viton, but the folks that make them will 'fess up if the right questions are asked.


FYI-

===========================

This is absolutely true, but the emphasis is on the word "reciprocating". A reciprocating application would be on a cylinder rod seal in your master cylinder or a motorcycle front fork tube, where there is substantial motion. Engineering is about making valid tradeoffs.

In the case of the caliper piston it moves only slightly in normal application and retraction, basically rolling the O-ring elastically.  This is also the reason for using the lower 75 durometer Viton.
