Is my clutch slave cylinder leaking?

[sterminare]

'24 ST 18,000mi

Did a little inspecting today and found what looks like weeping around the clutch slave cylinder. A bit of black muck that feels oily on my fingers (red arrows). And the boot looks discolored, and I scratched off the yellow tint with my fingernail (yellow arrow).

Brake fluid reservoir is at max fill line.

Can't tell if this is leaking brake fluid picking up dirt or if it's just grease coming from under the boots during actuation. Or am I just being a hypochondriac

It looks like a little dust is just sticking to some residual grease, I think you’re fine. You can pull the rubber boot off the end of the slave cylinder (at the yellow arrow) and see if there’s any wetness inside, that will confirm one way or the other.

Not in my opinion.

If you put your car under the magnifying glass in this way, you'll discover many things that are completely normal.

Those have a lot of sticky grease applied at the lever arm. Looks fine to me.
