Clutch MC leak, why?
I just overhauled (3 months ago) both the master and slave cylinders because the master was leaking, I was having trouble getting into 1st, and the fluid was all dark (someone on here told me that was a result of the rubber getting old and contaminating the fluid).
Shortly after I noticed a small leak in the same area as before (above clutch pedal). The leak has become a lot worse lately, so much so that I'm going to have to bleed the line. The fluid is dark also which really confuses me because the rubber should be new and not deteriorating.
What is causing these leaks in both the new and old cylinder mechanisms? (I did not buy new cylinders, just the spring mechanisms) Would an incorrect pedal height create a leak? Maybe the pedal is coming back too far allowing the plunger to dislodge from the cylinder slightly and leak??? Also, why is my fluid dark again? I ran enough clutch fluid through the lines the first time I bled it, that there shouldn't be this much residual rubber floating around in there. Please help! I drive this thing 25 miles each way to work in traffic. I gotta get this clutch straightened out. Thanks.

My clutch m/c leaks as well. It leaves a stain on the floor and my left foot! Anyway, I have been told that the brake fluid darkens as it gets old and collects moisture. I think you should just replace the m/c with a new one. They're pretty cheap and not worth driving yourself crazy over.

I agree. If you need your truck to go back and forth to work every day then just buy a new cylinder. I think that master cylinders are suppose to be honed when rebuilt, but I am not sure. Does anyone know that for sure?

if you just replaced the rubber and didnt clean the bore the same issues are likely to reoccur. use 400+ grit wet/dry on the inside, not to remove material but to create a fresh path for the cylinder to travel in.
id just get a new one though.
