Cipi, The almighty Shazam wrote something useful on this. Apart from the system being prone to water ingress, and needing regular bleeding, another factor can cause the clutch to "go away" after hard use. The clutch pushrod pushes against a bearing in the pressure plate. If the bearing is not spinning perfectly, the pushrod can spin in its tunnel. When it spins, to gradually pushes the piston in the slave cylinder back in its housing so, the next time you use the clutch - nada. A few pumps on the lever helps to get it back into position, but this is not easy when your braking for a hairpin and trying to change down at the same time. It is worse with an aftermarket slave cylinder, because the travel of the pushrod is reduced. BTW - I run a 998, and this is a recurring problem for me too. Good luck sorting it - I'm considering a Thorsten mechanical conversion. Spin |
