Leaking brake fluid, what is the location?

[foxhole]

Looking at the evidence of a leak but not much fluid coupled with the statement of losing a considerable amount, it sounds like it will be leaking into the footwell.

A very common failure.

I'm not ruling out that pipe but it's not my 1st choice

Yes caused a leak into footwell as it runs back thru bulkhead but was hidden by carpets soaking it up .
Needs better photos.

Is it the short hose to master cylinder, failed on a friends car was a simple replacement with a snap on hose connection at each end.

What’s the name of that hose?

If it is causing a leak in the footwell, does the slave cylinder and clutch need to be changed?

Edit
I see yours is a 2013 car so I would not have thought you'd have general deterioration yet. I was thinking it was much older.

Would it be this part?

I would suggest it is least likely to be the hose, much more likely the slave cylinder leaking, and where the pedal push-rod enters. The pipe is steel, apart from the lower end, where there is a flexible section. Changing either master, or it's pipe, does not involve any slave replacement, or any work on the clutch itself -rather there is a self-sealing quick release joint, which allows the master + upper section of pipe to be replaced, avoiding the need to bleed the hydraulics.

The slave cylinder leaking would be leaking into the footwell?

What I will do for cost efficiency is

1/ Change the pipe
If no joy
2/ Change the master cylinder
If no joy
3/ Change slave and clutch

Thing is, I could feel the leak with my finger from the pipe at connection with master cylinder so seems like there’s definitely an issue there - even if it be a missing seal

What do we think? Reasonable approach?

You obviously do have a leak at the master. If you also suspect a leak at the slave, check under the clutch bell housing, for fluid. There is always a deliberate gap there, to allow fluid to escape - check it is dry.

The only way to know, is to engage the Mk I eyeball!
