Hello List, 2 years ago I replaced both my master and slave cylinders with new ones from DMC houston. About 6 months ago I noticed my master cyliner leaking by my foot, and the clutch fluid decreasing. I purchased a new master cylinder from grady, and a new slave cyliner from specialtauto, so i would have them on hand and waited until christmas break (now) to change cylinders. I just changed the slave cylinder, and started on my master cylinder, I noticed the fluid in the master cylinder resivoir has turnned to a black jelly. There is quite literally 1 inch of just black thick gel mush in the resivior. I had changed fluid when I changed cylinders previously and used valvoline synpower (DOT 4). Was this the cause of my premature failure? Had I waited too long to change the fluid (2 years)? I have the SS braided clutch line, and a fuel grade line that runs from the resivoir to the master cylinder, so I would not suspect contamination from the hoses. I went and bought 2 bottles of valvolineABS (exceeds DOT 3 and DOT 4 standards) fluid, but I am not sure I want that fluid in my clutch system now. Do other people use this fluid for their clutch system? Thanks Joe P. VIN 17167 6808 [Non-text portions of this message have been removed]
