Leaking brake fluid, what is the location?

[Old Salt]

He is still losing fluid and needs it fixed. He has no idea where the leak is but Ford do. Let them fix it and he can get on with his life.

Loss of fluid from the clutch system, should not affect the brakes - both use the same reservoir, but the clutch master fluid, is tapped off much higher than the brakes.

Yeah so brakes haven’t been affected I just get notified to at brake fluid level is low. I think the pipe going from master cylinder to salve cylinder is leaking as per pictures. When I get it I will check it and see if the seal is on etc. I feel that is the issue. To be continued..

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.

Update: so I took the pipe that was suspected to be leaking. I thought maybe the seal wasn’t put it but the seal was there and while handling it I lost it.
Put the pipe back in, loosened the bleed nipple and started pumping the clutch. The pipe from the master cylinder was obviously leaking because the seal wasn’t there anymore, the bleed valve was also leaking. But under the footwell there was a leak as per video.. what’s going on here?

Can't make head nor tail from that picture

Was it leaking from the pushrod area ?

Never mind, it’s all leaking from the joint of the pipe and master cylinder I figured, need to either replace the top of the pipe or maybe the whole master cylinder.. to be continued

I had a leaking clutch master cylinder on our old Golf this year so I replaced it. That also had a stiff plastic pipe feeding it with fluid from the master cylinder reservoir. After I had fitted the new master cylinder, I couldn’t get a good seal on the pipe and it kept leaking. A new pipe was £20 and there was no guarantee that that would work as I used a pattern part cylinder and I suspect the inlet was slightly thinner than the original so I just chopped a ten inch section from a piece of rubber hose and used that. My mate said brake fluid would make it swell up like a slug with salt on it so as a test, I dropped a 1” section of the same hose into a jug with some brake fluid in it and I check it now and then. It’s fine.

Ford advised me to change the master slave and clutch. When I asked them where the leak was they basically said they didn’t know

But they showed a picture of the area? Same area as you show ?

They showed the footwell, I’ve driven the car since and put paper in the footwell completely dry, they don’t know what they’re doing

Ok. They know it can only be the supply, the master cylinder, the feed or the slave cylinder.

I think they know where to look and what to do.

Is this the footwell ?

No, maybe didn’t explain properly

Ahh, Ford dont know what they are doing!
