Elan S4 clutch

Operating the cylinder with pedal and brake line disconnected will help isolate whether you do or don't have a master cylinder problem

Thanks Roger,
That's about the same size as my original pushrod. Unfortunately I was finding gear changes rather notchy when clutch was adjusted correctly as per the workshop manual.
I found Brian's measurement and drawing very misleading which led me to fitting an adjustable rod several mm longer than your own measurement.

Based off of the new information about a notchy gearchange from your other topic, I'd investigate whether the slave pushrod is adjusted correctly and change the master pushrod back to the original one.
