Is it normal for the slave cylinder to leak brake fluid from the bellows when it is removed from the clutch fork? THis is the 2nd time it has happened to me. The first time was when I changed the clutch around 20,000 miles ago & the 2nd was just now after rebuilding the gearbox as the input shat bearing had gone. Each time I didn;t notice the leak until I was re-attaching the clutch slave cylinder. It's as though leaving it hanging around causes it to leak out of the bellows. I would expect a new cylinder to last longer than 20K. I did however notice this time what I thought was an oil leak near the sump. I now wonder if it actually is brake fluid driping down! It doesn't appear to hve used any fluid though.

Thoughts appreciated. I will be buying another slave cylinder!

Hi

It shouldn't leak.

Did you press the clutch pedal before reattaching the slave? I don't think you would :roll: , but that can blow the piston out of the cylinder and cause a leak.

It would be best to replace it.

I know it should last longer than 20k, but you found it in time and saved problems later.

I didn't press the clutch but I also didn't consider that I could have pulled or knocked the shaft out as I had to leave the slave cylinder dangling while taking the gearbox out. Maybe in future I need to tape or cable tie the rod in!

I will investigate the failed part when I get time which will be the weekend now! In fact I may still have the original one too which I can have a look at too.

I tend to keep the broken/replaced parts (as long as they are small) as they are handy for reference!

You can't pull the piston out! pulled the bellows off to have a look. Must be crappy quality parts or they seal wears due to the angle the clutch fork sits........
