I used SRAM DOT grease on the piston seals when 1 lever got sticky.
I have some from Avid, the package is so big it will last me 1000 years if not more.
The left blue circle area is outside of the actual hydraulic system, so I'd guess clean it well then use a light oil
Thanks, I went for the same oil I use on my chain. By the way, the ball joint pointed by the arrow is also outside the hydraulic system :nerd:

Yeah I meant the seals on the piston after that. Hayes told me a dab of grease on the end of the ball joint. I used DOT grease because it was close but I'm sure something else would work too, like Slick Honey.

Do any of you with Dominions have squeaky levers?
When 1 of my levers was getting sticky, it was also a bit noisy. I replaced the bearings first, then greased the ball end, and finally cleaned and greased the piston seals. The last one did the trick - there was a tiny bit of grit stuck on one of the seals.

Has anyone tested Cura 4s with the new-ish FCS lever? They claim it increases leverage and some reviews indicate it provides more power along with being slightly longer, but I can't seem to find much info aside from the NSMB review. Anyone know how much it changes the leverage and if it's a big improvement?

Also, if anyone wants to add Intend Trinity to the spreadsheet: they claim 17mm pistons, 9.5mm master, and mechanical leverage of 7.3 with overall of 46.78:1. I haven't verified on mine, though.

Yes, I had this problem on one set. I don't think I ever solved it, instead I put them on my wife's bike and it helps me keep track of her in the woods :D

Joking aside, I seem to recall Hayes telling me you could remove the lever and lightly grease the pivot. I never tested that, though. I definitely remember how irritating it was, so you aren't alone. Maybe call Hayes and see what they suggest.

I'm not really annoyed by it, but yeah I'll message them and see or just lube pivot.

I was flicking them out of habit yesterday, and a buddy was looking around asking if anyone else can see the bird chirping nearby :rofl:

Hayes CS is really quick to respond in my experience.
