Hi all, OK I'm using an early coffin type Master Cylinder, my original cylinder marked as 93 had begun to leak and was generally well weathered, so I've bought a second hand one marked 98 and looking in better condition although there was a bit of a residue inside the reservoir. Having tried out the replacement I found it has no pumping effect, I tried pumping fluid back through the system to bleed out the air, but still nothing. Has anyone any suggestions? or experience of replacing the seals (assuming kits are available) I'm guessing there must be a circlip maybe under the rubber gaiter? All assistance gratefully accepted, as I'm a bit frustrated with it at the moment, Bitza.
