What are the signs of a failing clutch slave cylinder?

[98OrientBlue]

Looking back at my notes, my first clutch went out suddenly while driving due to a failed slaved cylinder. That was 8 years and 67k ago. Not wanting to repeat that again, I wonder, are there signs of a failing slave cylinder?

I'm not getting any slippage on the clutch itself, but when I have the pedal depressed, usually in stop and go traffic, I can feel a slight "tremor" in the pedal as it goes between 1/2 and fully depressed. It's hard to describe the feeling: sort of like a grinding feeling coming through the pedal. It is pretty light; nothing overly alarming.

My first clutch went out at 102k, so this one isn't quite there yet. Any thoughts?

Thanks!

A failed slave will leak, really no other failure mode except perhaps to seize up. If it doesn't leak and moves freely it's good.

is it a new thing youre feeling? as the clutch mechanism is hydraulic, and vibrations end to end will be felt thru the complete system. could be master cylinder, clutch fork, etc.

I'm not sure if it's a new thing; maybe I just notice it more, just due to how many miles are on it. Thanks, I'll keep an eye on the brake fluid reservoir.
