Question
Sorry Barrie but I probably wasn't clear on my first question ,,,, I am not replacing my slave cylinder but replacing my 1973 midget clutch master cylinder, any tricks to bleeding it ?

Thanks

Answer
Hi Steve.  If you are only changing the clutch master cylinder, you should not need to bleed anything.  The only time you need to bleed the system is if the slave cylinder has air in it.

So long as the pipe to the slave cylinder has not completely drained, when you fill up the master cylinder, any air in the pipe will rise to the top and vent through the master cylinder.  Leave it to settle for a minute or two, then operate the clutch a few times, and then top it up again.
