Deperate for help, replaced master clutch cylinder, than replaced slave master cylinder, even after bleeding system, the clutch pedal will eventually in a couple of minutes hit the bottom, will replacing the clutch damper help, what is its purpose, can it be bypassed, and what else could be causing this problem.

Hi there,

Thank you for the donation,

The clutch damper is just a device that helps remove any shock loading from the hydraulic system, I have never known of one to give this problem, but there is alway the first time. I would be more inclined to suspect that the new master is faulty, this dose happen, the hydraulic system is very basic, the master displaces fluid the moves the slave piston, if there is a leak in the slave it will be wet under the boot, if the master is by-passing internally, the piston will drop as fluid by pases the pressure seal with out any external leakage.

I don't think that there will be any, I have not done this myself, but just considering the system, I don't think that if anything you may a slightly different feel in the pedal, but the pressure and through should be the same.

Hi there,

Thank you for the great feedback, did you bypass the damper? What effect did it have on the feel of the clutch and did it help with your initial problem.

Yes I have bypassed it, but you were right about the initial problem, it is still the same as before, so I will put a new master clutch cylinder in and leave the damper bypassed. And see how that works. Thanks
