Hey All

At the risk of prompting a calamari thread ......... :D

I know there are two diameters 30 & 31 mm. Are there different thicknesses too ?

My RGS clutch is loosing fluid past the slave cylinder even after fitting a new O ring.

The new O ring looked to be of a smaller thickness.....  :-\

Silicon grease IIRC - sachets that come with Brembo caliper and master cylinder repair kits, for example. I usually have some left over, so it's handy to keep for the occasions when a little smear on your rubbers could make a big difference.... :D
 
The "correct grease" is an interesting topic. The Brembo rebuild kits have a little envelop of grease, but I don't recall ever seeing a description of its use in that multi-language instruction page that accompanies the kit.  Just what should you do with it?  I've been told that hydraulic bits should be wetted with hydraulic oil only, but then what's the grease for?
 
and anyway the clutch slave cylinder is not like a caliper with a square section hydraulic seal, it is just an "O" ring, I think that the only items in it that Brembo made were the piston, and the dust seal, so not realy even a Brembo item?

Lawrence,

You actually read all that stuff??  :o :D

I liberally coat all components with the supplied grease before stuffing everything back together.  Quickly dissolved by brake fluid once in use.

I could imagine that the grease would be perfect for conserving the rubber bits, ie, for exhibition bikes without fluid in the braking system (bevel Ducatis in their glass cases...).
