Guess I had a right to be concerned!!! Took my Z out of winter storage last week. Clutch system was fully bled last July with Motul RBF600. Clutch reservoir was at the max mark and fluid was clear when the car was put in storage. Checked the fluid today after having driven 3 times for a total of about 150 miles (mainly highway) and noticed the fluid was a greyish colour. Fluid was still at the max mark in the reservoir and pedal pressure was normal. Decided to bleed the system. After running about 400 mL of new fluid through the system, the grey colour still remains. The pics show the fluid that was collected. (It appears blacker than it actually is in the pics). Car history is as follows:
Car has 12K miles on it. Clutch fluid has been changed at least twice per year. Have always used Motul RBF600. Always have been easy on the clutch.
Replaced the stock CSC with the Z Speed HD CSC 3 years ago when car had about 3K miles on it. Also installed the insulated clutch hose. (The CMC was changed at the same time as recommended by Z Speed).
Replaced the stock clutch pedal assembly with the RJM pedal assembly shortly after installing the HD CSC.
Replaced the stock CMC with the RJM HD CMC last year when car had about 10K miles on it.
All was well until today. Now I'm a bit stumped since I suspect that if the CMC had failed, I'd see a loss of pedal pressure … and if the CSC had failed, I'd see a loss of fluid. However, neither has occurred.
Anyone have any thoughts? I plan to contact Joe at Z Speed and Ryan at RJM to see what they think. Such a PITA.
