The replacement cylinder came in the mail. It doesn’t have a rod so I assume I am supposed to re-use the one I have. I wonder if the rod simply pulls out of the cylinder? I can’t really tell with the new one because the rubber boot hides everything.

Also, do I need to drain the system down at the slave cylinder or can I just remove the fluid from the reservoir and not end up with a geyser erupting under my dash before I can plug the lines?

My car does not have a separate clutch reservoir but instead uses the brake reservoir. I think I figured out which of the tandem brake reservoirs feeds the clutch cylinder.

I haven’t had much luck finding any step by step directions for this. I once rebuilt the master brake cylinder on a Triumph Spitfire but that was 30 years ago.
Any help or links or diagrams would be great, thanks!
