I have just put my 748 back on the road, and the clutch slave cylinder started to leak. When I put the new seal in I noticed that the fluid and cylinders were dirty, presumably having worked its way through the slave cylinder.

The new seal is working fine, so far, but I notice that despite cleaning and purging the system thoroughly the fluid in the master cylinder resevoir is dirty again. However I was in DKs showroom yesterday and they had several 748/996's in stock, and I noticed that most of them had dirty fluid too!

So the question is the dirt a factor in causing the system to leak, and is dirt ingress normal? Finally is there anything that can be done to reduce it?
