Vibration of rod to slave cylinder pressure loss fluid degrade?

[clutch3227]

Let me rephrase the question.

I have a stick shift car and the clutch fork Is rapidly vibrating attached to a push rod which touches a hydraulic piston inside the slave cylinder... After a few hours the car is unable to shift smoothly anymore because the clutch fork has less travel....

The car never had this problem of fluid degradation until just after the pressure plate was replaced and the oscillation was discovered... Of course if you replenish the fluid It shifts normally again for a few hours. The clutch master and slave cylinder have been replaced with many different brands. I don't know if there was an oscillation previously. The fluid level is never lower in the reservoir.

Can a vibration rapidly degrade the maximum pressure of break fluid?

Typically "many brands" use the same company to rebuild them and just put their name on the box. That company sets up a line and everyone else subcontracts to them. Probably the clutch or throw-out bearing has failed as well.

There is nothing wrong with the fluid.

The throughout bearing and clutch plate are wobbling.
