Clutch judder - mscott
My car has a hydraulic clutch and this has started to judder on take up. I know that judder can be due to contamination of the clutch plates with oil, but have noticed that the level of clutch fluid in its reservoir has fallen a little. So my question is; could clutch fluid leak from somewhere to cause clutch judder?

Thanks

Yes , renew the clutch slave cylinder. The seal on the front of the slave cylinder can go and the fluid will eventually find its way onto the gearbox input shaft and clutch. This also allows air to drawn back into the system. The clutch can judder for 2 reasons, 1. Fluid onto the input shaft cleans it and drys it , this causes the clutch friction disc to stick on the splines , 2. Air is drawn back into the hydraulic system, this can be temporarily be cured by bleeding but this will not solve the problem. The only solution is to renew the cylinder and hope that the clutch plate isn't sticking on the shaft, otherwise it will be a new clutch!
