I am currently rebuilding my mini, however I am unsure whether or not to service the clutch master cylinder whilst it is off or leave it as is? Is it a case of ‘If it isn’t broke, don’t fix it’ or should I be replacing the seals regardless?

If, and that might be a big if, you can find good quality seals I would do it now. Because if you don't do it now you might have to do it shortly after the car is back on the road. And that's not a fun job in my experience.

That’s what I was worried about… the seals are currently the original seals so I know the quality is good but if I buy a service kit will the seals be as good? Or do I just leave as is and hope?

The kits we stock are genuine AP rather than aftermarket

If changing the master cylinder, it is wise to fit a new flexible hose to the slave cylinder plus a new slave cylinder as well.

The factory advice is to re-rubber the clutch (and brake) hydraulics every 3 years or 40,000 miles. While it's off, may as well overhaul it.

I have recently changed the clutch master cylinder due to a fault which turned out to be the flexible hose. I am about to change the brake master cylinder, which is sensible as I have a single line system (Mk.1 Cooper 'S') and it's a well used rally car.
It's very easy and not expensive, except for fitting the clevis pins (worst job on a Mini?) I use an R-pin on the clutch clevis, but a proper split pin on the brake clevis pin.
In fact I have moved to the latest plastic masters.

Ok perfect, thank you all, I will overhaul it whilst it’s off!

MASTER CYLINDER CLEVIS PIN REMOVING AND FITTING TOOL
"A handy little tool for removing and replacing the master cylinder clevis pin. Sloped leading edge helps the tool to get behind the pin head for removal and the spring top stops it from falling into the bulkhead and holds it in place for replacement."
