I know you talk about it in the past but no firm answer....My clutch expansion tank in front is always overfilled after an hour drive. Some of you are suggesting in previous post (here or renntech) to replace the clutch slave cylinder other are talking about the accumulator or even both. As per repair manual there is a test to do for the accumulator which is: 1. Cold start engine (accumulator temperature approx. 20°C) and let run for approx. 20 seconds
(accumulator is full).
2. With the engine switched off, depress the clutch pedal repeatedly until an abrupt rise in pedal resistance
against your foot can be felt (accumulator is empty). While doing this, count the number of depressions
carried out up to the point of the rise in pedal pressure!
3. If the number of times the pedal was depressed is over 35, the accumulator is −arrow− faulty and must be
replaced!

I did it on my car and no difference even after 100 depressions of the pedal. Can you check on your car if this test is valid and let me know. Because I don't understand why a faulty accumulator can cause fluid migration. To me an accumulator is an inline reservoir who provide a sudden surge protection on the hydraulic system or extra fluid under pressure (bladder type)in case of hydraulic system failure . At least on the aircraft that I am working on...

Thanks for your help, info and replied, J.P.
